Pre-Galvanized Cold Rolled Welded Steel Pipe

Our pre-galvanizedcold rolled welded steel pipe has greatly enhanced corrosion resistance. It is made from our galvanized widesteel strip with the outer wall and welding seam being zinc plated. The zinc coating can be thickened up to 275g/㎡upon request of customer. A typical application of our product isto make the engineering components and light industrial products that arerequired to have pretty high corrosion resistance. Using our product to transferthe low pressure non-corrosive fluid is also a good idea.
