Packaging steel strip plastic CaoRao belt type profile type of channel steel belt cross section shape of two surface has three respectively shouldered and three grooves, the outer surface of the inner barrel turning first be in conformity with the type of channel steel belt shape of spiral groove, on special machine tool steel strip coil by the electric heating. Steel strip contraction after cooling, can ensure each layer with steel belt. Each layer of the both ends of the strip welding on Jane. On each meshing grooves between each layer of steel belt, which can absorb a part of the axial force formed by internal pressure. Type CaoRao belt requires both the belt fit closely, and to make each type of channel steel belt mesh each other, so the channel steel with special machine tools have higher accuracy; Steel strip by a dedicated rolling mills, high technical requirements, and because a one-way round belt, forcing the container when the internal pressure to produce torque, is often caused by tripping, and axial strength even container axial fracture accident may happen.
