Ppgi Hot Dipped Pre Painted Color Coated Galvanized Steel Coil

Color-coated coils use hot-dip galvanized steel coils as the substrate, and the color-coated steel coils are first surface pretreated, then coated with one or more layers of liquid coatings by roller coating, and finally baked and cooled. Coatings used include polyester, silicon modified polyester, high durability, corrosion resistance and formability. 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. Galvanized steel, PPGI, is coated completely with zinc. While Galvalume steel, PPGL is coated with aluminum, zinc, and a small amount of silicone. email: sales@ whatsapp: 8613964085002 The spray paint structure generally consists of five parts. 1) Topcoat: block the sun and prevent ultraviolet rays from damaging the coating; when the topcoat reaches the specified thickness, it can form a dense shielding film to reduce wa
