Al-Zn-Mg alloy coated steel is a new type of high corrosion resistance coated steel.
Product origin:
China
High-aluminum zinc-aluminum-magnesium
New type of highly corrosion-resistant coated steel plate
Zinc aluminum magnesium plate
Corrosion resistance mechanism
Product advantages
If under the same environment, the lifespan of Al-Zn-Mg steel products (with high aluminium content) can be increased by 1/3 longer than that of galvalume with the same coating, and it is more suitable for the marine and livestock environments.
Ten-week cyclic Q-Fog test (Q-fog CCT)
After 10 weeks of cyclic corrosion comparison experiments, there was no obvious change on the surface of the Al-Zn-Mg samples (AM150 gsm and AM100 gsm), a little red rust appeared on the surface of the galvalume sample (AZ150 gsm), and a large area of rust appeared on the surface of the galvalume sample (AZ100 gsm).
Eleven-month marine environment exposure
After 11 months of marine environment exposure experiments, there was no obvious change on the surface of the PPAM (AM50 gsm) sample, while salt frost appeared locally on the surface of the PPGL (AZ50 gsm)sample.
Fourteen-month outdoor acid rain environment exposure
After 14 months of exposure to outdoor acid rain environment, there was no obvious change on the surface of the Al-Zn-Mg samples (AM150 gsm and AM100 gsm), but the surface of the galvalume sample (AZ150 gsm) began to rust, and the surface of the galvalume sample (AZ100 gsm) had been rusted over a large area.

Shinmade's Pre-Painted Galvalume Steel Coils are specially designed to meet the diverse needs of modern construction. Featuring excellent corrosion resistance and strong adhesion of paint, PPGL coils are the ideal choice for exterior building components such as roofing systems, wall panels, industrial warehouses, and prefabricated house structures. Our coils are suitable for both residential and industrial uses, combining aesthetics with long-term durability in harsh environments.
CRC Full Hard Specification： Thickness: 0.06 -2.0 mm. Width：750-1320 mm General inner diameter：508 mm Max.outer diameter：2000 mm Max.weight：26000 KG Standard：JIS G 3141
Shinmade offers PPGL steel coils in a variety of coating systems to suit different project needs. Our coils are available in PE (Polyester), HDP (High-Durability Polyester), SMP (Silicone-Modified Polyester), and PVDF (Polyvinylidene Fluoride) finishes. Each system is designed to withstand specific environmental conditions—from general weathering to high UV and chemical resistance. Whether you are designing urban infrastructure or rural housing, we help you choose the right coating for the job.
At Shinmade, we supply PPGL steel coils that deliver long-lasting performance under extreme weather conditions. The galvalume substrate provides superior protection against rust, while the top paint layer enhances both UV resistance and surface finish. Whether you need materials for coastal buildings or high-humidity environments, our PPGL coils ensure structural integrity, vibrant colors, and resistance to fading, chalking, and peeling over time.
Galvalume is a coating consisting of zinc, aluminium and silicon that is used to protect the metal from oxidation. And it would be less likely to rust than normal galvanized steel. These products are mainly used in the outdoor metal facades, panels and roofing.
Shinmade's PPGL coils not only offer high mechanical strength and formability but are also an environmentally friendly solution for green construction projects. With recyclable content and low VOC coatings, our products align with global sustainability standards. Whether used in eco-friendly housing or industrial zones with green certifications, Shinmade PPGL steel supports long-term energy efficiency and reduced maintenance costs.
