PPGI Pre-Painted Galvanized Steel Coil 1200mm Width with 150g/m² Zinc Coating and ≥2500h Salt Spray Resistance
PPGI (Pre-Painted Galvanized Steel Coil) is manufactured using cold rolled steel or galvanized steel as the base material. Through surface pretreatment and continuous roller coating, followed by baking and cooling, these coils offer lightweight construction, aesthetic appeal, and superior corrosion resistance. Ideal for construction, shipbuilding, automotive, appliances, and electrical industries, PPGI supports steel-for-wood substitution, efficient construction, energy conservation, and pollution prevention.
