Advantages of hot galvanized steel pipe compared with stainless steel

　　Hot dip galvanizing steel is a kind of steel with hot galvanizing layer obtained by immersing ordinary carbon steel or low-alloy structural steel in molten zinc bath, which is mainly used to prevent atmospheric corrosion of steel. Compared with stainless steel, if it is used to prevent atmospheric corrosion, the biggest advantage is low price. Generally, stainless steel components are made by cutting bending welding, depending on the thickness of stainless steel plate, Because of the cost, we usually don't use thick steel plate. So the mechanical strength is relatively poor.

　　ASTM A53 Hot DIP Pre Galvanized Stainless Steel Pipe is generally galvanized after welding of profiles, and it can also be made by welding steel plates and then galvanizing, but it can be made very solid without too much money. Generally, manufacturers don't care how much materials they use. So stainless steel is not as good as hot-dip galvanized steel
