Flat Rack Shipping Container

For project cargo, heavy machinery, and out-of-gauge freight, a flat rack shipping container provides the open-side and top-loading capability that standard enclosed containers cannot offer. Cargo such as long steel pipes, generators, tracked vehicles, pressure vessels, and prefabricated structural steel can be loaded from the top, side, or rear using cranes, forklifts, or hydraulic trailers. This flexibility is especially valuable in oil and gas, wind energy, construction, mining, and military logistics where large indivisible loads are common. The 20ft Flat Rack Container is engineered with a reinforced steel base frame and strong end walls, making it ideal for dense, compact cargo that needs a small but rigid platform. The 40ft Flat Rack Container extends the same structural design across a longer deck, allowing transport managers to handle longer beams, multiple palletized units, or oversized equipment with fewer securing complications. Unlike standard dry containers, these units have no fixed side walls or roof, so over-height and over-width cargo can often be shipped without extensive dismantling. The flush floor design and recessed lashing points also reduce snagging hazards and speed up cargo securing. The main technical parameters are listed below to support accurate route planning and safe load distribution.

• External dimensions: 20ft model 6,058 mm length × 2,438 mm width × 2,591 mm height; 40ft model 12,192 mm length × 2,438 mm width × 2,591 mm height
• Tare weight: approximately 2,700 kg for 20ft; approximately 4,200 kg for 40ft
• Maximum gross weight: 45,000 kg for both sizes, subject to road and port limits
• End walls: fully welded high-tensile steel frame, available in fixed or collapsible design
• End wall height: 2,591 mm standard; custom heights available on request
• Floor construction: 28 mm–30 mm thick steel deck with anti-slip profile; marine-grade plywood or wood flooring optional
• Lashing rings: recessed D-rings rated from 2,500 kg to 5,000 kg each, located along side rails and end rails
• Corner castings: ISO 1161 compliant, compatible with standard twist locks and lifting equipment
• Fork pockets: two pairs per side, sized for standard forklift tines during empty handling
• Surface treatment: zinc-rich primer with marine-grade topcoat; hot-dip galvanizing optional
• Documentation: valid CSC plate, ACEP information, and latest inspection report included

Every Flat Rack Shipping Container is fabricated from high-tensile Corten steel for the main rails, corner posts, and floor cross members, which delivers excellent resistance to corrosion, impact, and fatigue under repeated heavy loads. The side rails are reinforced with full-length plate sections to handle concentrated point loads from tracked vehicles, steel coils, or transformer feet, while the end walls can be folded down when units are positioned for compact return transport. During production, each unit is dimensionally checked, weld-inspected, and subjected to a floor load test before the CSC data plate is attached. Buyers can specify additional lashing points, higher end walls, removable stanchions, side brackets, or special coating systems to match project-specific requirements. All units are compatible with standard container spreaders, terminal tractors, and twist-lock securing equipment, which simplifies handling at ports, depots, and remote job sites. The open-platform layout also makes it easier to inspect the floor, verify lashing ring condition, and perform routine maintenance between shipments. For offshore and highly corrosive environments, hot-dip galvanizing is available to extend service life and reduce the need for frequent recoating. Manufacturers typically apply a two-pack epoxy primer and a marine-grade topcoat as standard, with additional stripe coats on welds and edges. After final inspection, the container is marked with gross weight, tare weight, net weight, and CSC approval details in line with the latest IMO/ILO/UNECE requirements. This open-platform approach supports safe, repeatable cargo handling and gives freight forwarders and project owners a practical platform for difficult over-dimensional moves. Transport planning is further simplified by the container's standard ISO footprint, which matches the same corner casting spacing used on standard dry and reefer units. This allows flat rack platforms to be stacked, secured, and transferred with the same equipment already available at most container terminals. For shipments that involve partial disassembly of machinery, the open deck provides a clean, accessible surface for chain and strap placement without the need to work inside a confined box.
