Aluzinc steel coil, also known as aluminum zinc magnesium or ZAM coated steel, represents a premium metallic-coated steel product engineered for superior long-term corrosion protection. This advanced material combines the sacrificial protection of zinc with the barrier protection and heat reflectivity of aluminum, resulting in a coil that significantly outperforms standard galvanized steel in harsh environments. As a leading aluzinc coil factory, ChinaCNU Steel produces high-quality coils that are ideal for demanding architectural, industrial, and agricultural applications where durability is critical. This page details the specifications, benefits, and competitive pricing of our Aluzinc coils, exported globally from our facility in Qingdao.
Our Aluzinc steel coils are manufactured to meet stringent international standards, offering a versatile range of dimensions and coatings to suit various project requirements. The table below outlines our standard production capabilities.
| Grade | Thickness (mm) | Width (mm) | Coating Type / Mass | Standard |
|---|---|---|---|---|
| DX51D, DX52D, DX53D | 0.15 – 2.0 | 600 – 1250 | Aluzinc (AZ150, AZ200) / ZAM | ASTM A792, EN 10346, JIS G3321 |
| S280GD, S350GD | 0.3 – 1.5 | 800 – 1200 | Aluminum Zinc Magnesium | EN 10346 |
| SGCC, SGCH | 0.18 – 1.2 | 700 – 1100 | AZ100 – AZ180 | JIS G3321 |
The exceptional corrosion resistance and thermal properties of Aluzinc steel coil make it the material of choice for a wide array of industries. Key applications include:
Selecting ChinaCNU as your supplier for aluminum zinc magnesium coated steel ensures you receive not just a product, but a reliable partnership. Here are the key reasons to work with us:
The price for Aluzinc (AZ) or ZAM coated steel coil varies based on daily raw material costs, coil dimensions, coating mass, and order volume. Our quotes are provided on an FOB Qingdao port basis, which offers you transparency and control over final shipping logistics. For the most accurate and competitive factory price, we encourage you to contact us with your specific requirements for a free, no-obligation quote typically delivered within 24 hours.
Aluzinc steel coil, specifically the aluminum zinc magnesium type, provides 2 to 4 times better corrosion resistance than standard galvanized steel. The aluminum component offers superior barrier protection and heat reflectivity, while the zinc provides sacrificial protection at cut edges. This makes ZAM coated steel for roofing in coastal or industrial areas a far more durable and cost-effective long-term solution.
For standard specifications, our production and preparation lead time is typically between 15 to 25 days after order confirmation and receipt of deposit. This efficient timeline is a key advantage of sourcing directly from a trusted Aluzinc coil factory in China like ChinaCNU Steel, ensuring your supply chain remains predictable.
We offer secure and flexible international payment terms, primarily by Telegraphic Transfer (T/T) or Letter of Credit (L/C). Standard terms involve a 30% deposit with order confirmation and the 70% balance before shipment. We work with buyers to establish mutually agreeable and secure payment methods.
To ensure our coils arrive in perfect condition, we use robust export-standard packing. Each coil is wrapped in waterproof paper, securely strapped with steel bands, and mounted on wooden pallets or in wooden crates. This method protects the aluminum zinc magnesium coated steel from moisture, handling damage, and corrosion during long-distance sea freight.
