A cargo container is manufactured using mash seam welding or CO2 laser welding technology. Automatic welding replaces the multiple sheets of corrugated steel used for the side and roof panels with continuous coils of steel, resulting in lower material costs and reduced material handling. A single horizontal mash-weld or CO2 laser weld seam is needed to produce each panel, which are produced by joining two side-by-side sheets at their inner edges. Press and die assembly forms reinforcing ribs. Each panel has four straight welding edges, which enable automated welding. The cargo container includes a frame assembly made of tubular beams.
