Q345B cold drawn square tube

Q345B cold drawn square pipe has good stability and is a composite structure. The epoxy resin coating center is reinforced welded steel pipe. The combination of this structure allows the steel pipe to have better stability. The pipe is not only not easy to corrode in the face of various corrosive media, but also has a relatively stable expansion coefficient, so the cold drawn square pipe is not easy to deform after use and can effectively extend the service life of the pipeline system.
