Metal anti-corrosion panels use steel plates as the substrate, and composite anti-corrosion functional films on both sides, also known as film-coated panels or film-coated tiles, are a new generation of anti-corrosion factory roof materials developed by Himei Metal. The main feature of the anti-corrosion coated board is that it will not rust or leak in various corrosive environments. The construction of the anti-corrosion coated board is the same as that of ordinary color steel plate. It can suppress any tile shape and fix it on the steel structure purlin with anti-corrosion screws.
