Hemaokang Steel (Shandong) Co., Ltd., established in 2025, has rapidly become a reliable supplier of high-quality steel products in the global market. With an annual export value of US$50 million to US$100 million and a dedicated team of 51–100 employees, we are committed to delivering superior materials to clients across North America, South America, Europe, Asia, Africa, and Oceania. Our Galvalume AZ150 Galvanized Steel Coil (also known as Aluzinc coil) combines the strength of steel with the corrosion resistance of aluminum-zinc alloy coating, offering exceptional durability and performance for a wide range of applications.
This product is manufactured using premium DX51D grade steel substrate, coated with a precise 150 g/m² (AZ150) aluminum-zinc alloy layer through a continuous hot-dip process. The result is a material that outperforms traditional galvanized steel in terms of corrosion resistance, heat reflectivity, and formability. Available in thicknesses from 0.5 mm to 2.0 mm and widths from 600 mm to 1500 mm, our Galvalume coil is ideal for roofing, wall cladding, home appliances, automotive parts, and industrial structures.
Backed by ISO9001 quality management system certification, our production process ensures consistent quality, tight tolerances, and excellent surface finish. Each coil undergoes rigorous inspection to guarantee compliance with international standards such as EN 10143, JIS G3312, and ASTM A792. Whether you need standard or customized dimensions, we have the flexibility to meet your specific requirements.
Key Features & Technical Specifications
- Superior Corrosion Resistance: The aluminum-zinc coating (55% Al, 43.5% Zn, 1.5% Si) provides up to 2–4 times longer service life than conventional galvanized steel in most environments.
- Excellent Heat Reflectivity: The metallic surface reflects up to 75% of solar radiation, reducing heat buildup in buildings and lowering energy costs.
- Good Formability & Workability: DX51D grade ensures excellent bending, stamping, and profiling capabilities without cracking or peeling.
- Surface Options: Available with chromate passivation, oiling, or skin-pass treatment to enhance anti-rust properties and improve paint adhesion.
- Customizable Dimensions: We offer precise slitting and cutting to meet your required width and length, with coil inner diameters of 508 mm or 610 mm.
- Wide Application Range: Suitable for roofing sheets, wall panels, gutters, downspouts, automotive components, HVAC ducts, and electrical enclosures.

Frequently Asked Questions
-
What is the difference between Galvalume and galvanized steel?
Galvalume uses an aluminum-zinc alloy coating (55% Al, 43.5% Zn) which provides superior corrosion resistance, especially in acidic or coastal environments. It also offers better heat reflectivity and durability compared to traditional galvanized steel. -
Can this coil be painted or coated further?
Yes, the surface can be treated with a primer or paint. Our standard chromated or oiled surface prepares the coil for further coating. We recommend using a compatible paint system for best adhesion. -
What is the typical lead time for orders?
Lead time depends on quantity and customization. For standard sizes, we usually ship within 15–20 days after order confirmation. Custom orders may require 25–30 days. Please contact us for exact timelines. -
Do you provide sample coils for testing?
Yes, we offer free samples (shipping cost may apply) for qualified buyers. Sample size is typically 1–2 meters of full width coil, or a small cut piece. Contact our sales team to arrange sample delivery. -
What certifications do you provide?
We are ISO9001 certified. Each shipment includes a mill test certificate (MTC) showing chemical composition, mechanical properties, and coating weight. Additional certifications can be arranged upon request. -
Is the coil suitable for outdoor use?
Absolutely. Galvalume is specifically designed for outdoor applications such as roofing, wall panels, and gutters. Its corrosion resistance and UV stability make it an excellent choice for long-term exposure. -
What packing options are available?
Standard packing includes anti-rust paper, plastic film, steel strapping, and plywood pallets for sea freight. We can also customize packing for inland transportation or special requirements. -
Can I order thickness or width outside the specified range?
We can produce limited quantities outside the standard range, depending on the mill's capability. Please inquire with our technical team for feasibility and minimum order quantity.
