Prepainted PPGI Corrugated Steel Sheet with SMP Coating for Wall Cladding

Galvalume substrate: 55% Al, 43.5% Zn, 1.5% Si hot-dip coating provides barrier protection plus sacrificial edge protection, better than ordinary galvanized steel in many outdoor environments.

Full RAL color system: standard RAL Classic colors and custom color matching by sample supported for architectural consistency.

Multiple paint systems: PE for general use, SMP/HDP for better weather resistance, PVDF for coastal, industrial and high-UV areas with longer color retention.

Typical AZ150 coating: AZ50-AZ150 g/m2 aluzinc coating options, AZ150 being a common roofing choice for balanced corrosion resistance and cost.

Corrugated strength: wave profile increases rigidity and spanning ability, common wave height 18-35mm, pitch 76-130mm depending on profile.

Lightweight roofing: 0.3-0.8mm base thickness commonly used, panel weight around 4-6kg/m2, reduces structural load and installation cost.

Weather and UV resistance: PVDF systems can offer 15-25 years of exterior service, salt spray resistance commonly 500h+ for PE and 1000h+ for PVDF.

Heat reflectivity: light-color PVDF or PE coatings help reflect solar heat and reduce cooling load in warehouses and factories.

Easy fabrication: panels can be cut-to-length, punched, bent, seamed and roll-formed without damaging the coating when correct tools are used.

Export-ready supply: MTC available, SGS/BV inspection supported, PVC film + waterproof paper + steel strapping + wooden pallet packing for sea freight.
