Gl - Galvalume Steel Coil from Nam Kim Steel is a hot-dip aluminum-zinc alloy coated steel product manufactured to JIS G 3321 standard using NOF technology. The coating composition consists of 55% aluminum, 43.5% zinc, and 1.5% silicon, applied to a carbon steel substrate. This alloy coating delivers superior corrosion resistance compared to galvanized steel, with a typical lifespan four times longer in harsh environments.
Available in thickness ranges from 0.20 to 2.0 mm and widths between 600 to 1250 mm, the coils are supplied with coating mass options from AZ50 to AZ200. The anti-finger layer reduces staining and oxidation, preserving surface shine and minimizing damage during stamping or rolling. Standard industry practice for galvalume coils includes tolerance adherence to JIS G 3321, with typical yield strength values of 250-350 MPa depending on base steel grade.
This product is primarily used for roofing, cladding, and structural applications in construction and automotive sectors. Buyers sourcing from Viet Nam typically confirm Incoterms such as FOB Haiphong or CIF destination ports, with packaging in export-standard coils wrapped for sea freight. Galvalume’s heat resistance and durability make it a preferred choice for long-term outdoor exposure in tropical or coastal climates.

Before ordering, verify the exact JIS G 3321 compliance and request mill test certificates (MTC) for chemical composition and mechanical properties. Confirm the coating mass (AZ value) aligns with your project’s corrosion resistance requirements, as higher AZ values offer longer service life but may impact cost and formability.
Logistics details such as Incoterms (e.g., FOB Haiphong), packaging type (export-standard coils with protective wrapping), and lead times should be clarified directly with Nam Kim Steel. Buyers should also confirm whether the supplier can accommodate non-standard coil dimensions or custom packaging for specific freight constraints.
Quality checks should include visual inspection for coating uniformity and surface defects, as well as third-party testing for salt spray resistance and adhesion. Request documentation for the anti-finger layer and any additional treatments. For structural applications, ensure the base steel grade meets your project’s yield strength and elongation requirements.
