This kind of steel tube is through cold drawn process with special profile mould by seamless steel tubes or welded steel tube.

Application:

Shaped seamless steel tubes are widely used in various structural parts, tools and mechanical parts.

Compared with round tubes, shaped tubes generally have larger moments of inertia and section modulus, and have greater resistance to bending and torsion, which can greatly reduce the structural weight and save steel.
