Prepainted Aluzinc Steel Coil, Prepainted Galvalume Steel Coil (PPGL)
Standard: ASTM/JIS/GBT/EN etc
Thickness: 0.12mm ~ 2.0mm
Width: 600mm ~ 1800mm
Shanghai Metal Corporation is a leading Prepainted Aluzinc Steel Coil, Prepainted Galvalume Steel Coil (PPGL) manufacturer and supplier.
Prepainted Aluzinc Steel Coil, also known as Prepainted Galvalume Steel Coil (PPGL), is a composite metal material consisting of a cold-rolled steel substrate, a 55% aluminum-zinc alloy coating, and a factory-applied organic paint layer. It is primarily used in construction for roofing, wall cladding, and sandwich panels, as well as in the manufacturing of home appliances like refrigerators and air conditioners. This product specifically addresses the need for enhanced durability in harsh environments by combining the superior corrosion resistance and high-temperature tolerance of the aluzinc substrate with the UV protection and aesthetic versatility of the pre-applied paint. Consequently, it effectively solves issues related to rapid rusting, paint peeling, and high maintenance costs associated with traditional uncoated metals, providing a long-lasting, low-maintenance building and manufacturing material.
If you want to know more about our steel products or Prepainted Aluzinc Steel Coil, Prepainted Galvalume Steel Coil (PPGL) price please feel free to contact us, we will reply you within 24 hours.

1. Superior Corrosion Resistance
Combines aluminum's barrier protection with zinc's sacrificial protection, lasting 2-3 times longer than standard galvanized steel. This significantly reduces long-term maintenance and replacement costs in harsh environments.
2. Exceptional Heat Reflectivity
Reflects up to 70% of solar heat radiation. This helps maintain cooler indoor temperatures, directly reducing air conditioning energy consumption and utility costs.
3. High-Temperature Stability
Maintains coating integrity at temperatures up to 315°C. It safely withstands high-heat industrial applications like oven casings and chimneys without degrading.
4. Excellent Formability
Features superior paint adhesion that prevents peeling or cracking during bending and stamping. This ensures high manufacturing yields and reduces scrap rates for fabricators.
-
1. Industrial Roofing & Cladding
Suitable for large-span factories and warehouses. The Al-Zn coating resists rust and reflects solar heat to reduce cooling costs. Recommended Structure Al-Zn AZ150 with PVDF/HDP topcoat.
2. Coastal Construction
Suitable for marine environments. The aluminum oxide layer acts as a robust physical barrier against salt spray corrosion. Recommended Structure Al-Zn AZ150 with PVDF topcoat and 2/2 backcoat.
