GB/T 12754 PPGL Coil – High-Performance Colour Coated Galvalume Steel
Core Advantages of Our GB/T 12754 PPGL Coils
1. Engineered for Long-Term Corrosion Resistance
Precision Substrate Coating: We strictly follow the standard’s requirements for Aluzinc (AZ) coating weight and adhesion. This ensures the base steel remains protected against rust even in high-humidity and industrial environments.
Salt Spray Endurance: Our products are tested to withstand extensive salt spray corrosion tests, proving their durability for outdoor roofing and cladding applications.
2. Consistent Quality Control & Mechanical Strength
End-to-End Inspection: From raw material testing to the final product, we implement the standard’s inspection rules for impact resistance, T-bend flexibility, and film hardness.
Zero-Defect Goal: The standardized judgment criteria ensure that every batch of PPGL coil delivers the same high level of performance, minimizing waste during your manufacturing process.
3. Highly Flexible Customization & Material Options
As per GB/T 12754 classifications, we offer a wide range of options to suit your specific project needs:
Diverse Substrates: Choose from Cold-Rolled (SPCC), Hot-Dip Galvanized (GI), or 55% Al-Zn Galvalume (GL).
Premium Coating Systems: Options include Polyester (PE), High-Durability Polyester (HDP), Silicon Modified Polyester (SMP), and Fluorocarbon (PVDF) for maximum lifespan.
4. Full Quality Traceability & Certifications
Transparent Supply Chain: Every shipment is accompanied by a Mill Test Certificate (MTC) containing detailed chemical analysis, mechanical properties, and coating thickness data.
Quick Issue Resolution: Our traceability system allows for rapid sourcing and feedback, ensuring total peace of mind for international importers and distributors.

FAQ about PPGL
1.what is GB/T 12754 Galvalume Coil
GB/T 12754-2019 is the current Chinese national standard for “Color Coated Steel Sheets and Strips.” Here, Galvalume Coil typically refers to color-coated coils (PPGL) with a hot-dip aluminum-zinc alloy (55% Al – 43.4% Zn – 1.6% Si, abbreviated as AZ) as the base material, offering double protection from both the aluminum-zinc layer and the organic coating.
2.Are you a manufacturer or a trading company?
We are a factory with over 10 years of sales experience
3.How do you guarantee the quality?
1) Sourcing only from top-tier, certified mills.
2) Conducting our own rigorous in-house QC checks.
3) Providing a formal Mill Test Certificate and our quality warranty for every shipment.
4.What color options are available for GB/T 12754 Colour Coated Galvalume?
We offer a full range of RAL K7 colors and customized patterns (wood, brick, camouflage). Our GB/T 12754 compliant coils ensure color consistency (ΔE ≤ 1.5) across different batches.
5.How does the Aluzinc coating weight affect the lifespan of the PPGL?
For GB/T 12754 standards, we provide AZ30 to AZ150 coatings. A higher AZ coating (e.g., AZ150) significantly extends the service life, especially in high-humidity and industrial areas.
