Custom Shaped Cold Drawn Seamless Tube

The custom shaped cold drawn seamless tube is widely used in a variety of structure, tool and mechanical part. Compared with round steel pipe, it generally has larger moment of inertia, section modulus and the strength of bending and torsion, which can reduce the structural weight and save steel largely.
