Galvanized square tube is a type of hollow, square-shaped metal tubing that has been treated with a layer of zinc on its surface to enhance its corrosion resistance and durability. The galvanized square tube is usually made by processing cold-rolled or hot-rolled steel sheets and then subjecting them to a galvanizing treatment to prevent corrosion caused by oxidation on the surface of the tube.
Galvanizing pipes is a fundamental process in the metalworking industry that significantly enhances the durability and lifespan of steel and iron components.
The galvanizing pipe is applying a protective zinc coating to steel or iron. The composition of zinc coatings is crucial for performance. The main phases include:
