Product Description
Seamless or Welded Octangon Steel Pipe GB/T 3094 Cold Drawn Tube 10# 20# Q195 Q235 Q345
Octagon Steel Tube is mostly seamless tube or welded tube, produced according to the Chinese Standard GB/T 3094, which is a standard for cold drawn shaped steel tubes.
Octagon Steel Tube is widely used in structural parts, tool and machinery parts. And the barrel compared to stainless steel Pipes generally have a greater moment of inertia and section modulus, flexural torsional greater capacity, can greatly reduce the structural weight, saving steel.
