The 40-foot flat rack container by Captain Container is specially designed and manufactured to transport heavy and oddly shaped cargo that may not fit into standard containers. Its folding ends provide flexibility for storage or transportation without any payload. When empty, collapsible end flat rack containers can be stacked on top of each other by simply placing both end walls down. The flat rack is constructed using high-quality steel, which offers excellent corrosion resistance and strength to withstand harsh weather conditions during sea transportation.
