Platform Shipping Container

For freight forwarders and project cargo managers, the 20ft Platform Container is a core piece of equipment when moving goods that cannot be loaded through standard container doors. This open-deck unit is designed to handle oversized, heavy, or irregularly shaped cargo such as industrial machinery, pipes, generators, steel beams, and prefabricated structures. The platform design eliminates side walls, roof, and end doors, allowing top, side, and rear loading by crane, forklift, or roll-on equipment. Built around a high-tensile steel base frame, the 20ft platform container offers dual forklift pockets and ISO corner castings, making it compatible with standard intermodal handling systems. Operators can secure cargo with recessed lashing rings spaced along the side rails and end rails, reducing movement during transit. The absence of fixed enclosures also reduces tare weight compared with enclosed containers, which can increase the allowable payload for dense shipments. This flexibility makes the 20ft platform container a preferred choice for ports, construction sites, mining operations, and oil and gas projects.

The Platform Shipping Container is manufactured with a robust frame made from weathering corten steel, which provides excellent resistance to corrosion in marine and industrial environments. The deck surface is available in either 28mm pressure-treated marine plywood or a steel plate option, depending on load type and duty cycle. Cross members are spaced to distribute point loads evenly, while the main rails are reinforced to resist bending under concentrated heavy cargo. Each unit includes four ISO 1161 corner castings that allow standard twist-lock stacking, chassis mounting, and lifting by spreader or crane. Lashing rings are welded into the side and end rails at regular intervals and are rated for substantial tie-down forces, allowing operators to comply with international cargo securing regulations. Forklift pockets are integrated into the base frame to permit empty repositioning without requiring special handling gear. The finish is typically a primer and marine-grade topcoat, with optional hot-dip galvanizing for extended service life in wet or salty conditions. This open platform design is particularly effective for cargo that exceeds standard container width or height, as long as the load is within the platform footprint and properly secured.

20ft Platform Container Technical Parameters

Key Design Features and Build Materials

• Main frame: High-tensile corten steel side rails and cross members with anti-corrosion treatment.
• Deck options: 28 mm pressure-treated plywood or 4 mm steel deck plate, both rated for heavy point loads.
• Corner castings: ISO 1161 compliant cast steel corners for stack, lift, and secure chassis mounting.
• Lashing points: Recessed D-rings welded into side and end rails, spaced approximately every 1,000 mm along the perimeter.
• Forklift pockets: Two through-pockets on the base frame for empty repositioning; optional side pockets available.
• Finish: Marine-grade primer and topcoat, with optional hot-dip galvanizing for offshore use.
• Stacking: Designed for stacking up to 8 high when loaded and up to 12 high when empty in select configurations.
• Compliance: CSC, ISO 1496/5, and ABS/GL type approval available upon request.

Typical Cargo Applications

• Heavy machinery and excavators
• Steel coils, beams, and pipes
• Transformers and generators
• Precast concrete elements
• Wind energy components and tower sections
• Boats and oversized vehicles

Loading and Securing Recommendations

• Always distribute load evenly across cross members to avoid concentrated stress points.
• Use chains, tensioners, and corner protectors rated for the total mass and expected acceleration forces.
• Secure cargo to lashing rings using ISO 1161 or equivalent fittings for reliable restraint.
• Check the load plan against the deck's maximum point load before loading.
• Confirm that the transport mode (road, rail, or ship) can accept over-width or over-height cargo.
