PPGI / Prepainted Steel Coil
PPGI (prepainted galvanized steel coil) is produced by coating high-performance organic paint on hot-dip galvanized steel substrate. Combining metal strength, anti-rust performance and decorative colors, prepainted steel coil is the most popular material for roofing, wall cladding and decoration.
Standard Specifications
Thickness: 0.15mm – 3.0mm
Width: 800mm – 1500mm
Coating: top coat 20μm + primer 5μm
Paint system: PE, SMP, HDP, PVDF
Color: full RAL colors and custom patterns
Coated galvanized steel coils refer to double-protection steel materials with zinc layer plus organic coating. This upgraded coated galvanized steel coil greatly improves weather resistance, acid and salt spray resistance, suitable for harsh outdoor and coastal environments.
