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

An open side container is a shipping container with doors that run the full length of one or both long walls, instead of the solid steel side panels on a standard box. Open those doors and you can load and unload straight from the side, along the whole 20ft or 40ft length. That single change solves the biggest limit of a normal container: you no longer have to feed everything in through the end doors.

How the door system works

The side doors are bi-fold, hinged panels that fold back like an industrial version of a folding wardrobe door. Each panel can swing between about 180 and 270 degrees, and you can open one section or the whole side at once. Common layouts are:

  • Full open side with no centre post.
  • One centre post with two doors.
  • Three posts with four doors, for more rigidity.

Even with the whole side opening, the container stays weather-tight when closed. Rubber gaskets, multi-point locks and drainage channels keep water out, and the sealed unit handles wind of roughly 150 km/h.

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.

How it is built

An open side uses the same industrial materials as a standard container, with reinforcement to make up for the missing fixed wall:

  • Corten weathering steel for corrosion resistance.
  • Reinforced frame members to keep the box rigid without the solid side.
  • 28 mm marine-grade plywood floor.
  • Heavy-duty forged steel hinges and zinc-plated hardware.

What open side containers are used for

The full-length opening pays off wherever end-door access is slow or impossible:

  • Construction sites storing long structural materials.
  • Warehouse and distribution overflow with side-loading docks.
  • Retail pop-ups, event spaces and exhibitions.
  • Agricultural equipment and supplies.
  • Military and emergency logistics.
  • Conversions into offices, studios, cafes and garages, where the ready-made opening is a head start.

What is an open side container used for? 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. Contact Infinex for availability and pricing through our services page or contact us directly to discuss your requirements.

Advantages and trade-offs

Advantages

  • Full perpendicular forklift access from the side.
  • Loading and unloading roughly 30 to 50 percent faster than end-only boxes.
  • Room for long or awkward cargo a standard door cannot take.

Buying or hiring an open side container in Singapore

As a container supplier in Singapore, INFINEX sources open side containers new and used, for sale and lease. Tell us the size, condition and how you plan to load, and we will match the right unit. Browse the full open side container range, or see ISO standard containers if a standard box will do.

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.
