AL-Zn

Welcome to our high-performance AL-Zn Alloy Coated Steel series, globally recognized as Galvalume (GL). This advanced steel product is continuously hot-dip coated with an alloy consisting of approximately 55% Aluminum, 43.4% Zinc, and 1.6% Silicon.

This unique metallurgical composition creates a dual-protection mechanism: the zinc provides excellent sacrificial galvanic protection, while the aluminum barrier ensures exceptional long-term defense against rust and atmospheric corrosion. Compared to traditional galvanized steel, our AL-Zn steel delivers significantly longer service life, outstanding heat reflectivity, and remarkable oxidation resistance, making it the ultimate choice for extreme environments.

Custom Processing & OEM Solutions: We provide highly flexible, made-to-order manufacturing to perfectly match your project’s technical specifications:

• Custom Coating Weight: We strictly control the AL-Zn coating mass (from AZ30 to AZ150+) to suit your specific environmental exposure and budget requirements.
• Anti-Fingerprint (AFP) Treatment: We offer clear or tinted (blue, green, yellow) Anti-Fingerprint resin coatings to enhance surface durability, improve roll-forming performance, and prevent handling stains.
• Precision Slitting & Flatting: Master coils can be custom-slit into precise narrow strips, or leveled and sheared into flat steel plates according to your CAD dimensions.
• Roll Forming (Roofing Profiles): Ready to build? We can profile the AL-Zn coils into various corrugated roofing and wall cladding sheets, providing ready-to-install construction materials.

Key Industrial Applications: Thanks to its unmatched durability and heat resistance (withstanding temperatures up to 315°C without discoloration), AL-Zn steel is essential in the following sectors:

• Architecture & Construction: The premier material for commercial roofing, wall cladding, rainwater gutters, and pre-engineered steel buildings requiring a long lifespan.
• Home Appliances: Ideal for the internal backplates of ovens, microwaves, and toasters due to its excellent thermal reflectivity and high-temperature oxidation resistance.
• HVAC & Ventilation: Widely used in manufacturing spiral ducts, ventilation components, and air conditioning outer casings.
• Electrical & Infrastructure: Providing extreme weather resistance for outdoor electrical cabinets, switchgear enclosures, and telecommunication tower components.
