US Patent 7854577 Freight container

The freight container is constructed with relatively thin sidewalls of relatively high-strength steel, permitting thinner corrugations. This results in a greater internal width for the container, while still having an external width not exceeding the nominal 102″ or 2.6 meter national and international standards. By forming the sidewalls of sufficiently high strength materials, the sidewalls may be constructed to have a thickness not exceeding one inch each, thereby providing a nominal internal width of 100″ for the container. This permits the placement of U.S. standard pallets having lengths and widths of 56×44 inches in an alternating array, with each pallet group forming a square of 100″ on a side. In this manner, a total of twenty-four pallets may be placed within the freight container.
