Key Advantages of Our ASTM A755 PPGL Coils
1. Certified Quality & Market Compliance
International Access: Fully meets market entry requirements for North and South America.
Strict Testing: Each batch undergoes rigorous testing for T-bend flexibility, impact resistance, and MEK rub to ensure consistent quality.
Project Ready: Ideal for EPC contractors and exporters requiring documented compliance with international material standards.
2. Superior Dual-Layer Corrosion Protection
The synergy between the substrate and organic coating provides industry-leading protection:
Aluzinc Substrate: The 55% Aluminum-Zinc alloy coating provides a self-healing sacrificial barrier, offering 2 to 6 times the corrosion resistance of traditional galvanized steel (GI).
Barrier Coating: Our pre-painted layers (Polyester, SMP, or PVDF) act as an impermeable shield against moisture, salt spray, and industrial pollutants, significantly lowering maintenance costs.
3. High Thermal Reflectivity & Weatherability
Heat Resistance: The Galvalume base withstands temperatures up to 315°C (600°F) without surface discoloration, reflecting heat to reduce cooling costs.
UV Protection: Engineered to resist chalking, fading, and cracking under intense UV radiation and thermal cycling. Our ASTM A755 coils maintain their vibrant color and structural integrity for decades.
4. Efficient Processing & Versatility
Formability: Designed for high-speed roll forming and deep drawing. The coating remains intact even during complex bending or stamping.
Turnkey Solution: Pre-painted in a controlled factory environment to eliminate on-site painting. This reduces construction time, minimizes environmental pollution, and ensures a perfectly uniform finish every time.

FAQ about PPGL
1.what is ASTM A755 Galvalume Coil
ASTM A755/A755M is a standard for pre-painted metal sheets and strips established by the American Society for Testing and Materials, covering pre-painted steel coil products with a hot-dip aluminum-zinc (Galvalume) steel substrate. Galvalume is a 55% aluminum-zinc alloy coating applied to the surface of cold-rolled or hot-rolled substrates through a high-temperature hot-dip process, forming a dense aluminum-iron-silicon-zinc alloy layer that provides far superior atmospheric corrosion resistance compared to ordinary galvanized steel.
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 is the difference between PVDF and SMP coatings on ASTM A755 PPGL?
PVDF (Polyvinylidene Fluoride) offers maximum chalking and fading resistance, ideal for extreme sun exposure. SMP (Silicone Modified Polyester) provides higher scratch resistance and hardness at a more cost-effective price point for commercial projects.
5.Does your ASTM A755 Galvalume meet the T-bend test requirements?
Absolutely. Our ASTM A755 PPGL coils pass the 0T-2T bend test without cracking or peeling, ensuring excellent formability for standing seam roofs and wall panels.
