More Details About Jianglin Stainless Steel Rectangular Tube
Stainless steel rectangular tube manufacturing main steps
- Step1, Material Preparation: Stainless steel plates are selected to meet rigorous standards, ensuring the material’s strength and a defect-free surface.
- Step2.Slitting and cutting: Stainless steel sheet coils are slit to specific widths to serve as the base material for further forming.
- Step3.Welding and Forming: Sheets are welded into round tubes using argon arc welding or plasma welding, with weld seams carefully treated for quality and consistency.
- Step4.Extrusion and Shaping: Round tubes are shaped into rectangular cross-sections through cold rolling or extrusion using precision moulds.
- Step5.Surface Treatment: Finished tubes are polished, brushed, or hairline-treated to improve appearance and enhance corrosion resistance.
