PPGI/PPGL prepainted galvanized steel coil

 Overview PPGI is pre-painted galvanised iron, also known as pre-coated steel, coil coated steel, color coated steel etc., typically with a hot dip zinc coated steel substrate.The term is an extension of GI which is a traditional abbreviation for Galvanized Iron. Today the term GI typically refers to essentially pure zinc (>99%) continuously hot dip coated steel, as opposed to batch dip processes. PPGI refers to factory pre-painted zinc coated steel, where the steel is painted before forming, as opposed to post painting which occurs after forming. Galvalume Steel:alloy protection, long-term protectionWith 55% aluminum, 43.4% zinc and 1.6% silicon alloy coating composed of gold ratio, a three-dimensional protection system was constructed by molecular structure optimization. In the salt spray filled coastal areas, acid rain frequent industrial heavy pollution areas, its corrosion resistance life can reach 2-4 times of the traditional galvanized steel plate; In the face of 250℃ high te…
