What Is an Open Side Container? Complete Guide to Specs, Uses and Pricing

Loading cargo through the narrow end of a standard shipping container is one of the biggest frustrations in logistics. Forklifts struggle with long loads, workers waste time arranging items single-file, and oversized materials simply do not fit through a 7-foot-wide door.

The open side container solves these problems by placing full-length doors along the long wall. In this guide, we cover what an open side container is, how the doors work, standard dimensions, real-world applications, pricing, and how it compares to other container types. Infinex can source open side containers for projects across Singapore in both new and used condition.

What Is an Open Side Container?

An open side container (also called a full-side access container, side-opening container, or side-door container) is a modified intermodal shipping container with bi-fold doors along one or both of its long walls instead of the conventional solid steel panels.

While a standard container only has cargo doors on the short 8-foot wall, an open side container opens up the full 20-foot or 40-foot length of its side wall. This gives operators the ability to load, unload, and access cargo from the side rather than being restricted to end-loading only.

The bi-fold doors are made from the same corrugated Corten steel as the rest of the container. When closed and sealed, the unit remains wind-tight and water-tight, just like a standard box. Structural integrity is maintained through a reinforced top rail, reinforced corner posts, and carefully engineered hinge systems.

Open side containers are built to ISO standards and are compatible with standard container handling equipment. They are available in both 20ft and 40ft lengths, in standard height (8ft 6in) and high cube (9ft 6in) configurations. For a full breakdown of sizing, see our container sizes guide.

Understanding the mechanism, design variants, and opening options will help you choose the right configuration. Bi-Fold Door Mechanism Each door panel is made up of two hinged sections that fold against each other when opened, similar to a closet bi-fold door but built to industrial standards. The doors swing open between 180 and 270 degrees, and when fully opened, the panels fold flat against the adjacent wall or corner post, leaving the entire side opening completely clear. Each panel rides on heavy-duty hinges welded to vertical posts, designed to support 150 to 250 kg per panel while withstanding repeated opening and closing cycles. Doors can be opened individually or all at once, giving you flexibility for partial or full access. Door Configurations Full open-side (no centre post): Two large bi-fold assemblies meet in the middle. When opened, the entire wall is clear with no vertical obstruction. Best for very long or wide items. One-post/two-door: A single vertical centre post divides the side into two openings, each with its own bi-fold assembly. Adds structural rigidity while providing generous access. Four-door/three-post: Three vertical posts create four equal door sections. Highest structural strength, commonly chosen when stacking is required. Most open side containers also retain the standard end doors, giving you dual-access capability. Weatherproofing and Security Despite having an entire wall that opens, open side containers are engineered to be fully weather-tight when closed: Rubber gaskets: Continuous seals along every door edge, post junction, and threshold create a water-tight barrier Multi-point locking: Cam-action lock rods engage at the top, bottom, and middle of each door frame, with high-security padlock hasps Drainage channels: Door tracks and bottom rails direct water away from the interior Wind rating: Closed and locked units meet the same wind resistance standards as conventional containers, typically rated for sustained winds up to 150 km/h https://app.envato.com/search/photos/3e91e6b3-9ae2-4f67-a910-615e4992888f?itemType=photos&term=Open+Side+Container&sort=relevance Open Side Container Dimensions and Specifications Below are the standard dimensions for the most common open side container sizes. Exact measurements may vary slightly between manufacturers. 20ft Open Side Container (Standard and High Cube) Specification 20ft Standard 20ft High Cube External Dimensions (L x W x H) 6,058 x 2,438 x 2,591 mm 6,058 x 2,438 x 2,896 mm Internal Dimensions (L x W x H) 5,898 x 2,350 x 2,390 mm 5,898 x 2,350 x 2,690 mm Side Door Opening (W x H) 5,758 x 2,280 mm 5,758 x 2,585 mm End Door Opening (W x H) 2,340 x 2,280 mm 2,340 x 2,585 mm Tare Weight 2,550 to 2,800 kg 2,750 to 3,050 kg Maximum Payload 21,500 to 24,000 kg 21,000 to 24,000 kg Cubic Capacity 33.0 to 33.2 cbm 37.2 to 37.5 cbm 40ft Open Side Container (Standard and High Cube) Specification 40ft Standard 40ft High Cube External Dimensions (L x W x H) 12,192 x 2,438 x 2,591 mm 12,192 x 2,438 x 2,896 mm Internal Dimensions (L x W x H) 12,032 x 2,350 x 2,390 mm 12,032 x 2,350 x 2,690 mm Side Door Opening (W x H) 11,832 x 2,280 mm 11,832 x 2,585 mm End Door Opening (W x H) 2,340 x 2,280 mm 2,340 x 2,585 mm Tare Weight 4,200 to 4,800 kg 4,500 to 5,200 kg Maximum Payload 26,000 to 28,000 kg 26,000 to 28,500 kg Cubic Capacity 67.3 to 67.7 cbm 75.8 to 76.3 cbm Construction and Materials Open side containers use the same industrial-grade materials as standard shipping containers, with additional reinforcement to compensate for the opening side wall. Corten steel (weathering steel): Walls, roof, floor frame, and door panels are fabricated from Corten steel, which forms a protective rust layer that shields the underlying metal from corrosion. Ideal for containers exposed to rain, salt spray, and tropical humidity. Reinforced frame: The top side rail, corner posts, and bottom side rail are all reinforced with heavier gauge steel sections to maintain load-bearing capacity after removing the solid wall. Marine-grade plywood flooring: 28 mm thick, treated with insecticide and fungicide, rated to support forklift traffic and heavy point loads. Forklift pockets: Standard ISO-spaced pockets built into the base for lifting and repositioning. Heavy-duty hardware: Forged steel hinges designed for tens of thousands of cycles. All lock rods, handles, and cam keepers are zinc-plated or galvanised. Multi-layer coating: Zinc-rich primer, intermediate epoxy coat, and marine-grade polyurethane topcoat for long-term corrosion protection. Advantages of Open Side Containers Full forklift access from the side. A forklift can approach perpendicular to the container and place pallets anywhere inside without driving through a narrow 8-foot corridor. Faster loading and unloading. Multiple workers or machines can operate along the open side simultaneously. Side-loading can reduce handling time by 30% to 50% compared to end-loading. Oversized cargo capability. Items wider than the 7 ft 8 in end door can be loaded through the side opening, which stretches up to 38 ft 10 in on a 40ft unit. Reduced cargo damage. Items can be placed directly into position rather than being dragged or tilted through a narrow door. Easy access to all cargo. Every item is immediately reachable from the side, making inventory management and partial unloading far more practical. Outstanding conversion potential. The full-length opening is perfect for large windows, folding walls, serving hatches, or roll-up shutters, making these containers ideal for customised solutions. Storefront and display capability. When opened, the container creates a natural covered shopfront. The roof provides shade and rain protection while the full interior is visible. Weather-tight when closed. Rubber gaskets and multi-point locks ensure the container is fully sealed, meeting the same standards as conventional containers. Strong resale value. Limited supply and strong demand mean open side containers hold their value well. https://app.envato.com/search/photos/1325f9a0-18cb-4bc5-bef3-f56045e3edf1?itemType=photos&term=Open+Side+Container&sort=relevance Disadvantages of Open Side Containers Higher purchase cost. Open side containers cost approximately 1.5 to 2 times more than a comparable standard container due to complex door engineering and reinforced framing. Heavier tare weight. The reinforced frame and bi-fold doors add 200 to 500 kg, slightly reducing maximum payload capacity. Limited availability. These are a specialty product with limited production volumes. Lead times for new orders are typically 8 to 14 weeks. Used open side containers are particularly scarce. Lateral clearance required. The bi-fold doors need 600 to 800 mm of clearance to swing open, which can be a constraint in tight spaces. Reduced stacking capacity. Most are rated for 3 to 5 high stacking when empty, compared to 6 to 9 for standard containers. Always check the CSC plate. Door maintenance. Hinges, lock rods, and gaskets require periodic lubrication and inspection, especially in coastal or tropical environments. Open Side Container Uses and Applications Construction sites. Side-loading allows teams to store and access timber, steel beams, pipes, scaffolding, and heavy equipment without tight end-door manoeuvring. Multiple trades can access different sections simultaneously. Browse our range of products suitable for construction. Warehousing and distribution. Open side containers serve as flexible overflow storage during peak seasons. Side access makes pick-and-pack operations faster and enables proper first-in, first-out inventory rotation. Retail pop-up shops and events. When opened, the container transforms into a sheltered, branded retail or food-service space. Lockable when closed for overnight security. Ideal for markets, festivals, product launches, and trade shows. Agriculture. The side access is useful for loading large hay bales with a tractor-mounted loader or storing equipment too wide for standard doors. Military and emergency services. Side-loading enables rapid deployment and distribution of supplies, equipment, and field infrastructure in time-sensitive operations. Modular conversions. The pre-engineered full-length opening saves significant fabrication costs compared to cutting and reinforcing a standard container wall.

How Open Side Container Doors Work

The door system is what sets the open side container apart. Understanding the mechanism, design variants, and opening options will help you choose the right configuration.

Bi-Fold Door Mechanism

Each door panel is made up of two hinged sections that fold against each other when opened, similar to a closet bi-fold door but built to industrial standards. The doors swing open between 180 and 270 degrees, and when fully opened, the panels fold flat against the adjacent wall or corner post, leaving the entire side opening completely clear.

Each panel rides on heavy-duty hinges welded to vertical posts, designed to support 150 to 250 kg per panel while withstanding repeated opening and closing cycles. Doors can be opened individually or all at once, giving you flexibility for partial or full access.

Door Configurations

  • Full open-side (no centre post): Two large bi-fold assemblies meet in the middle. When opened, the entire wall is clear with no vertical obstruction. Best for very long or wide items.
  • One-post/two-door: A single vertical centre post divides the side into two openings, each with its own bi-fold assembly. Adds structural rigidity while providing generous access.
  • Four-door/three-post: Three vertical posts create four equal door sections. Highest structural strength, commonly chosen when stacking is required.

Most open side containers also retain the standard end doors, giving you dual-access capability.

Weatherproofing and Security

Despite having an entire wall that opens, open side containers are engineered to be fully weather-tight when closed:

  • Rubber gaskets: Continuous seals along every door edge, post junction, and threshold create a water-tight barrier
  • Multi-point locking: Cam-action lock rods engage at the top, bottom, and middle of each door frame, with high-security padlock hasps
  • Drainage channels: Door tracks and bottom rails direct water away from the interior
  • Wind rating: Closed and locked units meet the same wind resistance standards as conventional containers, typically rated for sustained winds up to 150 km/h

An open side container is used for any application that benefits from full-length side access, including construction site storage, warehousing, retail pop-up shops, agricultural storage, military logistics, and modular building conversions. 2. Can an open side container be shipped by sea? Yes. Open side containers are built to ISO standards and can be shipped on container vessels, trailer chassis, and rail. Ensure the doors are properly secured and sealed according to carrier requirements. 3. Are open side containers waterproof? Yes. When all doors are closed and locked, the rubber gaskets and multi-point locking system create a weather-tight seal meeting the same standards as conventional shipping containers. 4. Can I stack open side containers? Yes, but with reduced capacity. Most are rated for 3 to 5 high stacking when empty. Always check the CSC plate on the specific unit for its approved stacking weight. 5. Can the side doors be removed? Yes. The bi-fold doors are mounted on bolt-on hinges and can be removed if a permanent full-side opening is desired. This is commonly done for conversion projects. 6. Do open side containers have end doors too? Most open side containers retain the standard double doors on the short end wall, giving you dual-access capability. Side-only models (no end doors) are less common. 7. Can I convert an open side container into a shop or office? Absolutely. Open side containers are among the most popular choices for container conversions. The full-length opening provides a ready-made shopfront, display area, or large window opening. Infinex offers customised container solutions for fit-outs of all types. 8. How quickly can I get an open side container in Singapore? New one-trip containers typically have lead times of 8 to 14 weeks. In-stock units can often be delivered within 3 to 7 business days.

Construction and Materials

Open side containers use the same industrial-grade materials as standard shipping containers, with additional reinforcement to compensate for the opening side wall.

  • Corten steel (weathering steel): Walls, roof, floor frame, and door panels are fabricated from Corten steel, which forms a protective rust layer that shields the underlying metal from corrosion. Ideal for containers exposed to rain, salt spray, and tropical humidity.
  • Reinforced frame: The top side rail, corner posts, and bottom side rail are all reinforced with heavier gauge steel sections to maintain load-bearing capacity after removing the solid wall.
  • Marine-grade plywood flooring: 28 mm thick, treated with insecticide and fungicide, rated to support forklift traffic and heavy point loads.
  • Forklift pockets: Standard ISO-spaced pockets built into the base for lifting and repositioning.
  • Heavy-duty hardware: Forged steel hinges designed for tens of thousands of cycles. All lock rods, handles, and cam keepers are zinc-plated or galvanised.
  • Multi-layer coating: Zinc-rich primer, intermediate epoxy coat, and marine-grade polyurethane topcoat for long-term corrosion protection.

Advantages of Open Side Containers

  • Full forklift access from the side. A forklift can approach perpendicular to the container and place pallets anywhere inside without driving through a narrow 8-foot corridor.
  • Faster loading and unloading. Multiple workers or machines can operate along the open side simultaneously. Side-loading can reduce handling time by 30% to 50% compared to end-loading.
  • Oversized cargo capability. Items wider than the 7 ft 8 in end door can be loaded through the side opening, which stretches up to 38 ft 10 in on a 40ft unit.
  • Reduced cargo damage. Items can be placed directly into position rather than being dragged or tilted through a narrow door.
  • Easy access to all cargo. Every item is immediately reachable from the side, making inventory management and partial unloading far more practical.
  • Outstanding conversion potential. The full-length opening is perfect for large windows, folding walls, serving hatches, or roll-up shutters, making these containers ideal for customised solutions.
  • Storefront and display capability. When opened, the container creates a natural covered shopfront. The roof provides shade and rain protection while the full interior is visible.
  • Weather-tight when closed. Rubber gaskets and multi-point locks ensure the container is fully sealed, meeting the same standards as conventional containers.
  • Strong resale value. Limited supply and strong demand mean open side containers hold their value well.

Loading cargo through the narrow end of a standard shipping container is one of the biggest frustrations in logistics. Forklifts struggle with long loads, workers waste time arranging items single-file, and oversized materials simply do not fit through a 7-foot-wide door. The open side container solves these problems by placing full-length doors along the long wall. In this guide, we cover what an open side container is, how the doors work, standard dimensions, real-world applications, pricing, and how it compares to other container types. Infinex can source open side containers for projects across Singapore in both new and used condition. What Is an Open Side Container? An open side container (also called a full-side access container, side-opening container, or side-door container) is a modified intermodal shipping container with bi-fold doors along one or both of its long walls instead of the conventional solid steel panels. While a standard container only has cargo doors on the short 8-foot wall, an open side container opens up the full 20-foot or 40-foot length of its side wall. This gives operators the ability to load, unload, and access cargo from the side rather than being restricted to end-loading only. The bi-fold doors are made from the same corrugated Corten steel as the rest of the container. When closed and sealed, the unit remains wind-tight and water-tight, just like a standard box. Structural integrity is maintained through a reinforced top rail, reinforced corner posts, and carefully engineered hinge systems. Open side containers are built to ISO standards and are compatible with standard container handling equipment. They are available in both 20ft and 40ft lengths, in standard height (8ft 6in) and high cube (9ft 6in) configurations. For a full breakdown of sizing, see our container sizes guide. https://app.envato.com/search/photos/0eb3cb14-fd6f-44ce-b3dc-915d3b4ac1ad?itemType=photos&term=Open+Side+Container&sort=relevance How Open Side Container Doors Work The door system is what sets the open side container apart. Understanding the mechanism, design variants, and opening options will help you choose the right configuration. Bi-Fold Door Mechanism Each door panel is made up of two hinged sections that fold against each other when opened, similar to a closet bi-fold door but built to industrial standards. The doors swing open between 180 and 270 degrees, and when fully opened, the panels fold flat against the adjacent wall or corner post, leaving the entire side opening completely clear. Each panel rides on heavy-duty hinges welded to vertical posts, designed to support 150 to 250 kg per panel while withstanding repeated opening and closing cycles. Doors can be opened individually or all at once, giving you flexibility for partial or full access. Door Configurations Full open-side (no centre post): Two large bi-fold assemblies meet in the middle. When opened, the entire wall is clear with no vertical obstruction. Best for very long or wide items. One-post/two-door: A single vertical centre post divides the side into two openings, each with its own bi-fold assembly. Adds structural rigidity while providing generous access. Four-door/three-post: Three vertical posts create four equal door sections. Highest structural strength, commonly chosen when stacking is required. Most open side containers also retain the standard end doors, giving you dual-access capability. Weatherproofing and Security Despite having an entire wall that opens, open side containers are engineered to be fully weather-tight when closed: Rubber gaskets: Continuous seals along every door edge, post junction, and threshold create a water-tight barrier Multi-point locking: Cam-action lock rods engage at the top, bottom, and middle of each door frame, with high-security padlock hasps Drainage channels: Door tracks and bottom rails direct water away from the interior Wind rating: Closed and locked units meet the same wind resistance standards as conventional containers, typically rated for sustained winds up to 150 km/h https://app.envato.com/search/photos/3e91e6b3-9ae2-4f67-a910-615e4992888f?itemType=photos&term=Open+Side+Container&sort=relevance Open Side Container Dimensions and Specifications Below are the standard dimensions for the most common open side container sizes.

Loading cargo through the narrow end of a standard shipping container is one of the biggest frustrations in logistics. Forklifts struggle with long loads, workers waste time arranging items single-file, and oversized materials simply do not fit through a 7-foot-wide door. The open side container solves these problems by placing full-length doors along the long wall. In this guide, we cover what an open side container is, how the doors work, standard dimensions, real-world applications, pricing, and how it compares to other container types. Infinex can source open side containers for projects across Singapore in both new and used condition. What Is an Open Side Container? An open side container (also called a full-side access container, side-opening container, or side-door container) is a modified intermodal shipping container with bi-fold doors along one or both of its long walls instead of the conventional solid steel panels. While a standard container only has cargo doors on the short 8-foot wall, an open side container opens up the full 20-foot or 40-foot length of its side wall. This gives operators the ability to load, unload, and access cargo from the side rather than being restricted to end-loading only. The bi-fold doors are made from the same corrugated Corten steel as the rest of the container. When closed and sealed, the unit remains wind-tight and water-tight, just like a standard box. Structural integrity is maintained through a reinforced top rail, reinforced corner posts, and carefully engineered hinge systems. Open side containers are built to ISO standards and are compatible with standard container handling equipment. They are available in both 20ft and 40ft lengths, in standard height (8ft 6in) and high cube (9ft 6in) configurations. For a full breakdown of sizing, see our container sizes guide. https://app.envato.com/search/photos/0eb3cb14-fd6f-44ce-b3dc-915d3b4ac1ad?itemType=photos&term=Open+Side+Container&sort=relevance How Open Side Container Doors Work The door system is what sets the open side container apart. Understanding the mechanism, design variants, and opening options will help you choose the right configuration. Bi-Fold Door Mechanism Each door panel is made up of two hinged sections that fold against each other when opened, similar to a closet bi-fold door but built to industrial standards. The doors swing open between 180 and 270 degrees, and when fully opened, the panels fold flat against the adjacent wall or corner post, leaving the entire side opening completely clear. Each panel rides on heavy-duty hinges welded to vertical posts, designed to support 150 to 250 kg per panel while withstanding repeated opening and closing cycles. Doors can be opened individually or all at once, giving you flexibility for partial or full access. Door Configurations Full open-side (no centre post): Two large bi-fold assemblies meet in the middle. When opened, the entire wall is clear with no vertical obstruction. Best for very long or wide items. One-post/two-door: A single vertical centre post divides the side into two openings, each with its own bi-fold assembly. Adds structural rigidity while providing generous access. Four-door/three-post: Three vertical posts create four equal door sections. Highest structural strength, commonly chosen when stacking is required. Most open side containers also retain the standard end doors, giving you dual-access capability. Weatherproofing and Security Despite having an entire wall that opens, open side containers are engineered to be fully weather-tight when closed: Rubber gaskets: Continuous seals along every door edge, post junction, and threshold create a water-tight barrier Multi-point locking: Cam-action lock rods engage at the top, bottom, and middle of each door frame, with high-security padlock hasps Drainage channels: Door tracks and bottom rails direct water away from the interior Wind rating: Closed and locked units meet the same wind resistance standards as conventional containers, typically rated for sustained winds up to 150 km/h https://app.envato.com/search/photos/3e91e6b3-9ae2-4f67-a910-615e4992888f?itemType=photos&term=Open+Side+Container&sort=relevance Open Side Container Dimensions and Specifications Below are the standard dimensions for the most common open side container sizes.

Corten steel (weathering steel): Walls, roof, floor frame, and door panels are fabricated from Corten steel, which forms a protective rust layer that shields the underlying metal from corrosion. Ideal for containers exposed to rain, salt spray, and tropical humidity. Reinforced frame: The top side rail, corner posts, and bottom side rail are all reinforced with heavier gauge steel sections to maintain load-bearing capacity after removing the solid wall. Marine-grade plywood flooring: 28 mm thick, treated with insecticide and fungicide, rated to support forklift traffic and heavy point loads. Forklift pockets: Standard ISO-spaced pockets built into the base for lifting and repositioning. Heavy-duty hardware: Forged steel hinges designed for tens of thousands of cycles. All lock rods, handles, and cam keepers are zinc-plated or galvanised. Multi-layer coating: Zinc-rich primer, intermediate epoxy coat, and marine-grade polyurethane topcoat for long-term corrosion protection. Advantages of Open Side Containers Full forklift access from the side. A forklift can approach perpendicular to the container and place pallets anywhere inside without driving through a narrow 8-foot corridor. Faster loading and unloading. Multiple workers or machines can operate along the open side simultaneously. Side-loading can reduce handling time by 30% to 50% compared to end-loading. Oversized cargo capability. Items wider than the 7 ft 8 in end door can be loaded through the side opening, which stretches up to 38 ft 10 in on a 40ft unit. Reduced cargo damage. Items can be placed directly into position rather than being dragged or tilted through a narrow door. Easy access to all cargo. Every item is immediately reachable from the side, making inventory management and partial unloading far more practical. Outstanding conversion potential. The full-length opening is perfect for large windows, folding walls, serving hatches, or roll-up shutters, making these containers ideal for customised solutions. Storefront and display capability. When opened, the container creates a natural covered shopfront. The roof provides shade and rain protection while the full interior is visible. Weather-tight when closed. Rubber gaskets and multi-point locks ensure the container is fully sealed, meeting the same standards as conventional containers. Strong resale value. Limited supply and strong demand mean open side containers hold their value well. https://app.envato.com/search/photos/1325f9a0-18cb-4bc5-bef3-f56045e3edf1?itemType=photos&term=Open+Side+Container&sort=relevance Disadvantages of Open Side Containers Higher purchase cost. Open side containers cost approximately 1.5 to 2 times more than a comparable standard container due to complex door engineering and reinforced framing. Heavier tare weight. The reinforced frame and bi-fold doors add 200 to 500 kg, slightly reducing maximum payload capacity. Limited availability. These are a specialty product with limited production volumes. Lead times for new orders are typically 8 to 14 weeks. Used open side containers are particularly scarce. Lateral clearance required. The bi-fold doors need 600 to 800 mm of clearance to swing open, which can be a constraint in tight spaces. Reduced stacking capacity. Most are rated for 3 to 5 high stacking when empty, compared to 6 to 9 for standard containers. Always check the CSC plate. Door maintenance. Hinges, lock rods, and gaskets require periodic lubrication and inspection, especially in coastal or tropical environments. Open Side Container Uses and Applications Construction sites. Side-loading allows teams to store and access timber, steel beams, pipes, scaffolding, and heavy equipment without tight end-door manoeuvring. Multiple trades can access different sections simultaneously. Browse our range of products suitable for construction. Warehousing and distribution. Open side containers serve as flexible overflow storage during peak seasons. Side access makes pick-and-pack operations faster and enables proper first-in, first-out inventory rotation. Retail pop-up shops and events. When opened, the container transforms into a sheltered, branded retail or food-service space. Lockable when closed for overnight security. Ideal for markets, festivals, product launches, and trade shows. Agriculture. The side access is useful for loading large hay bales with a tractor-mounted loader or storing equipment too wide for standard doors. Military and emergency services. Side-loading enables rapid deployment and distribution of supplies, equipment, and field infrastructure in time-sensitive operations. Modular conversions. The pre-engineered full-length opening saves significant fabrication costs compared to cutting and reinforcing a standard container wall. Architects use these for offices, studios, cafes, garages, and modular homes. Explore Infinex customised container solutions for conversion options.

Below is a guide to current pricing in the Singapore and Southeast Asian market. Condition 20ft Price (USD) 40ft Price (USD) New (one-trip) $6,500 to $9,500 $9,500 to $15,000 Refurbished $5,000 to $7,000 $7,500 to $11,000 Used (good condition) $4,000 to $6,000 $6,000 to $9,000 40ft high cube open side containers sit at the upper end of these ranges due to additional material and higher demand. Used open side containers are significantly harder to find than used standard containers. When available, check the condition of doors, gaskets, hinges, and locking mechanisms carefully, as these components experience the most wear. Check our used container inventory for current availability. Why Open Side Containers Cost More The higher price reflects complex bi-fold door engineering, heavier structural reinforcement, specialised hardware components, lower production volumes, and additional quality control testing for door alignment and gasket sealing.
