Cold Rolled Square Tube material is cold rolled carbon steel strap with wall thickness 0.6mm to 2.0mm. When cold-rolled steel strap is heated to the annealing temperature, the surface color will turn black due to high temperature contact with air, which is called black stripping. The physical properties become soft, which is convenient for further welding to make steel pipes. The common hardness is 57HRB, and it can also be reduced to different hardness as needed.
