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.

FAQ
What is the difference between Aluzinc and standard Galvanized (GI) coil?
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.
What is the typical lead time for an order of Aluzinc coils?
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.
What are the payment terms for international buyers?
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.
How are the coils packed for export shipping?
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.
