Sanhe Steel is a professional manufacturer and supplier of Galvanized Steel Profiles in China. Galvanized pipes are welded steel pipes made from hot-rolled or cold-rolled steel strips or steel pipes, which are treated with galvanization to form a zinc protective layer. Their main functions are to prevent rust, resist corrosion, and extend service life. They are widely used in water supply and drainage, gas, fire protection, structures, wiring, and other engineering projects.
