Product Description
Galvanized rectangular tube is a hollow strip, also known as flat tube, flat square tube or square flat tube (as the name implies). Galvanized pipes are widely used in pipelines for transporting fluids, such as oil, natural gas, water, gas, steam, etc. In addition, they are light in weight while resisting bending and torsion, so galvanized pipes are also widely used in the manufacture of mechanical parts and engineering structure. It is also commonly used to make conventional weapons, barrels, shells, etc. Galvanized has stronger protective effect and strong corrosion resistance. The entire structure is made of zinc, which forms a dense quadruple crystal that forms a barrier on the steel plate, which effectively prevents the penetration of corrosive agents. Corrosion resistance protected by a zinc barrier. Zinc forms an insoluble oxide layer and acts as a barrier protection when the zinc sacrificial protective layer on cut edges, scratches and coatings wears away.
