AZ30-AZ150 prepainted galvalume steel, also known as PPGL steel or color-coated galvalume steel, is a versatile corrosion-resistant and decorative metal material for industrial construction, home appliance manufacturing, warehousing, logistics, and other applications. It combines the exceptional corrosion resistance of an aluminum-zinc coated substrate with the diverse aesthetics and functionality of a color coating.
Product Forms
As a professional supplier of prepainted galvalume steel, Wanzhi Group operates production lines and processing lines to offer customized PPGL steel solutions in multiple specifications. For use as raw materials in manufacturing, our prepainted galvalume steel comes in diverse forms including coils, sheets, strips, and more.
Prepainted Galvalume Steel – Coils
The most fundamental form of PPGL coil offers maximum flexibility and cost-effectiveness for deep-processing factories. Coil form facilitates transportation and storage, making it ideal for large-scale, continuous production lines. Customers can perform slitting, cross-cutting, or forming operations according to their equipment and production requirements. It is widely used in applications such as architectural wall and roof panels, and appliance casings, effectively reducing raw material costs and waste.
Prepainted Galvalume Steel – Sheets
Prepainted Galvalume Sheet: Roll-formed from prepainted Galvalume coils, these sheets are suitable for cutting and stamping applications such as appliance panels, electrical enclosures, and partition wall panels.
Prepainted Galvalume Profiled Sheets: Advanced forming equipment directly processes prepainted Galvalume sheets into specific waveforms (e.g., corrugated sheets, floor decking) or shaped panels. These profiles facilitate installation, significantly reducing on-site construction time and costs.
Prepainted Galvalume Sandwich Panels: Featuring prepainted aluzinc sheets as outer layers with polyurethane, rock wool, or polystyrene insulation cores. This composite panel integrates thermal insulation, heat resistance, fireproofing, and aesthetic appeal, making it an ideal cladding material for industrial buildings, cold storage facilities, and commercial structures.
Prepainted Galvalume Steel – Strips
Using precision slitting equipment, we cut wide prepainted galvalume coils into narrow strips of specific widths as required by customers. This form is primarily used in applications demanding precise width specifications, such as lighting fixtures, ceiling grid systems, furniture edging, and small components.
Prepainted Galvalume Steel – Packaging
Beyond diverse product forms, we offer specialized packaging solutions. For long-distance maritime transport or harsh environments, we provide reinforced waterproof and rust-proof packaging to ensure products arrive intact at global customers’ doorsteps.
- Coils: Utilizing moisture-proof paper, galvanized iron sheets, steel corner protectors, and high-strength steel strapping to secure coil shape, preventing unraveling or impact damage during transit.
- Flat/Shaped Sheets: Employing wooden or steel pallets with protective paper or plastic film between sheets. The outer layer is covered with galvanized iron sheets to effectively prevent scratches. Secured with steel strapping for moisture and dust protection.
