This aluminum zinc steel coil is a hot-dip coated product with an alloy composition of 55% aluminum, 43.5% zinc, and 1.5% silicon, delivering corrosion resistance that exceeds galvanized steel in most atmospheric conditions. The coating weights range from 30 to 275 g/m², providing tailored durability for roofing, cladding, and structural applications where longevity is critical. Supplied in widths from 750 mm to 1250 mm, the coil is available in multiple RAL colors to meet architectural and industrial design requirements.
The material combines the barrier protection of aluminum with the sacrificial protection of zinc, making it ideal for environments with high humidity, temperature fluctuations, or industrial pollutants. Typical applications include agricultural buildings, industrial sheds, and residential roofing, where the alloy’s self-healing properties prevent red rust formation at cut edges. Standard industry practice for this grade includes a minimum yield strength of 220 MPa and a tensile strength of 300 MPa, with elongation typically exceeding 20% for formability.
Buyers in the construction and automotive sectors source this coil for its lightweight yet durable properties, which reduce structural load without compromising strength. The product is traded internationally under standard export packaging, with each coil secured on wooden pallets and wrapped in waterproof material. Common trade terms for bulk orders include FOB Ningbo or Shanghai, with lead times averaging 20 to 30 days depending on order volume and custom color requirements.

Before ordering, verify the exact coating weight and width specifications to ensure compatibility with your project requirements. Request the supplier’s mill test certificates to confirm the alloy composition and mechanical properties, as these are critical for structural and aesthetic performance. Check that the RAL color codes match your design standards, as variations can occur between batches.
Confirm the Incoterms offered by Nantong Gaoya Steel Structure Co., Ltd., with FOB Ningbo or Shanghai being common for bulk shipments. Clarify lead times, which typically range from 20 to 30 days, and ensure packaging meets your handling and storage needs. Discuss payment terms, as suppliers often require a 30% deposit with the balance due before shipment for first-time buyers.
Conduct quality checks upon receipt, including visual inspection for coating uniformity and dimensional accuracy. Request third-party inspection if the order volume justifies it, particularly for large construction projects. Ensure all documentation, including packing lists, commercial invoices, and certificates of origin, is provided to facilitate customs clearance in your country.
