Product Description

Product Introduction

Aluminum zinc alloy coated stel is composed of 55% aluminum, 43.4% zinc and 1.6% silicon. The corrosion resistance of aluminized zinc steel coil is mainly due to the protective function of aluminum. When the zinc is worn, the aluminum forms a dense layer of alumina that prevents the corrosion resistant material from further eroding the interior.
