Cargo containers made from corrugated FRP sheets are the lightest and the toughest containers. A concealed structure with two back doors and a top is totally leak proof. This weighs 1/3rd of the container if made in steel. A well designed structure is sturdy and 100% repairable. Less weight hence fuel average increases also life of the vehicle incleases. Extra payload, fill more, earn more. Rust proof. As FRP material being itself an insulater, the temperature in the container will remain less compared to steel. FRP wind deflector (wind cutter) is provided to the container which gives a aerodynamic shape to the vehicle thus cutting off wind resistance and running smoothly which ultimately increases fuel average. The wind deflector can also be used as a mini storage space.
