GB/T 3094 Cold Drawn Square And Rectangular Tubes

Introduction of GB/T 3094 square and rectangular tube

GB/T 3094 square and rectangular tube is made through cold drawn process. The inner and outer surface is smooth, without burrs, and has high dimensional accuracy, which can meet high precision and high quality requirements of construction industry. Due to its the cross-sectional shape and uniform wall thickness, there will be no significant thermal deformation or cracking on its surface during cold processing, avoiding defects that may exist in other processing methods. In addition, GB/T 3094 square and rectangular tube has high strength and excellent corrosion resistance, and good impact performance under low temperature, which is suitable for various harsh environments.
