Galvalume Steel Pipe Tube Galvalume weld Steel Tube GL pipe tube
The corrosion resistance of "galvalume steel pipes" is mainly due to the protective function of aluminum. When the zinc is worn, the aluminum forms a layer of dense alumina that prevents the corrosion-resistant material from further corroding the interior. There is a test was carried out under the premise of hot-dip galvalume steel sheets and galvanized steel sheets of the same thickness, plating layer and surface treatment method. Aluminized zinc has excellent corrosion resistance than hot-dip galvanizing, and its service life is 2-6 times that of ordinary galvanized steel.
