PPGI & PPGL Product Categories

PPGI – Prepainted Galvanized Steel Plate / Coil

• Substrate: Galvanized steel (GI)
• Coating System: PE / SMP / PVDF
• Paint Thickness: 10–35μm (top) / 5–20μm (back)
• Zinc Coating: Z30–Z275 g/m²
• Width Range: 600–1250mm
• Colors: RAL color system or customized
• Common Applications: Roofing sheets, wall cladding, household appliances, metal doors, light steel structures

PPGI steel sheets are widely chosen for projects requiring cost efficiency and stable appearance, especially in standard roofing and cladding applications.

PPGL – Prepainted Galvalume Steel Plate/Coil

• Substrate: Al-Zn coated steel (GL)
• Al-Zn Coating: AZ30–AZ150g/m²
• Paint System: PE / SMP / PVDF
• Heat Resistance: Better than PPGI
• Corrosion Resistance: 2–4x longer than GI in many conditions
• Applications: PPGL roofing sheets, solar panel structures, marine buildings, industrial warehouses

PPGL coated plates and coils are commonly supplied for projects exposed to higher humidity, heat, or corrosive conditions, such as coastal or industrial zones.
