The floor construction of the box trucks for sale combines structural integrity with operational versatility. Standard configurations feature 3mm-thick hot-rolled steel flooring, quenched and tempered to 350HB hardness, capable of withstanding 8,000 kg/m² static load. For electric models like the Futian Auman, an aluminum-magnesium alloy composite floor is optional, reducing weight by 40% while maintaining equivalent load capacity (6,500 kg/m²). The floor surface is treated with a non-slip polyurea coating (R11 slip rating), resistant to oil, chemicals, and abrasion, with embedded steel T-track channels (100mm spacing) for securing cargo restraints. In refrigerated variants, the floor incorporates a 50mm insulated layer of polyurethane foam, thermally broken to prevent cold bridging. Underneath, cross-members are constructed from high-strength steel (yield strength ≥ 550MPa), spaced at 300mm intervals to ensure uniform load distribution. For custom floor solutions—such as composite wood laminates for light cargo or stainless steel finishes for food-grade applications—consult our materials specialists for detailed specifications and load-bearing calculations.
