Product introduction

　　The Al-Mg-Mn roof is lighter because the density of aluminum in many metal elements is relatively small, but the strength of aluminum magnesium manganese alloy is relatively high. The Al-Mg-Mn roof panel has high strength and corrosion resistance due to its composition, special processing and heat treatment. In addition, the Al-Mg-Mn roof also has the ability of antirust, because the outer layer of aluminum can form an oxide film, so as to prevent metal corrosion, acid and alkali resistance are better.
