Process of Pre painted GI Sheet
Pre-painted GI Sheet consists of a substrate, a primer and a topcoat. The GI Sheet is pre-treated and then roll coated with an organic coating, cured and cooled to produce a painted steel sheet that conforms to the international standards of ISO, ASTM, JIS, EN, etc. The GI Sheet is then coated with an organic coating, which is applied to the substrate by a roller.
Galvanized steel sheet cleaning (degreasing, pickling) → surface passivation treatment.
Roller coating technology: front and back double-sided synchronous coating, speed 100-200m/min, precision ±1μm.
Baking and curing: Segmented oven (preheating → curing → cooling), PVDF needs high temperature above 230℃.
Cutting.
Molding.
Covered with protective film or coated with anti-rust oil.
