Stainless steel is resistant to chemical corrosion, air or water and other weak corrosion media. Stainless steel covers ordinary stainless steel and acid resistant steel. cold rolled weathering steel coil Q235NH, Ordinary stainless steel is generally not resistant to chemical corrosion, while acid resistant steel is generally stainless. The use of stainless steel is mainly to maintain the original appearance of the building for a long time.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the cold rolled weathering steel coil Q235NH steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of cold rolled weathering steel coil Q235NH seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
