Se-Chang Steel Co., Ltd supplies Alu-Zinc alloy coated steel (GA), a product of a continuous hot dip process with a coating composition of 55% aluminum, 43.4% zinc and 1.6% silicon. This Galvalume variant delivers superior corrosion resistance and heat reflectivity, making it a premium alternative to galvanized steel for demanding environments. The material is offered in thicknesses from 0.40 mm to 2.30 mm and widths from 800 mm to 2300 mm, with a minimum order quantity of 20 to 25 metric tons per 20ft container.
The alloy’s high aluminum content (over 80% in the coating layer) ensures it withstands prolonged temperatures up to 315°C without discoloration or oxidation, while its heat reflectivity reduces energy consumption in applications like HVAC ducting and roofing. The spangle finish is a delicate light silver, suitable for decorative use, and the material’s workability matches that of galvanized steel, with enhanced resistance to fine cracks in the coating layer. This product is widely used in roofing, cladding, automotive panels, and industrial applications where durability and energy efficiency are critical.
Buyers typically source this material for coastal and high-temperature environments, where its corrosion resistance outperforms traditional zinc-coated steel by three to six times. The product is exported in standard steel packing: coils in horizontal or vertical configurations, sheets as per customer order. Trade terms include FOB Busan, with payment options such as T/T advance 20%, L/C at sight, or L/C 90 days from B/L date. Delivery is scheduled within 45 to 60 days from L/C or the mill’s option, and all shipments adhere to export standards for steel.

Before ordering, verify the exact thickness, width, and coating composition to ensure compatibility with your project’s specifications. Confirm that the supplier can provide material test certificates (MTCs) for the batch, detailing the chemical composition and mechanical properties of the base steel and coating.
Logistics details to confirm include the packaging method (coil or sheet), delivery lead time (typically 45 to 60 days from L/C), and Incoterms (FOB Busan is standard). Discuss payment terms such as T/T advance or L/C options, and ensure the supplier can accommodate your preferred shipping and insurance arrangements.
For quality checks, request samples for visual inspection of the spangle finish and dimensional accuracy. During production, insist on third-party inspection for coating weight, thickness tolerance, and heat resistance tests. Documentation should include MTCs, packing lists, and compliance certificates for industry standards like ASTM A792 for Galvalume.
