1. What Information Is Required for Galvalume Steel Coil Inquiry?
A galvalume steel coil inquiry requires clear technical specifications to ensure an accurate quotation, as product performance depends on grade, coating weight, and dimensions. When contacting GNEE STEEL, provide the following core details:
Steel Grade: Common grades include DC51D+AZ, S280GD+AZ, G350, and ASTM A792M (the global mainstream standard for galvalume steel).
Specification: Thickness (0.12–6.00 mm), width (600–1500 mm), and coil weight (3–15 tons).
Coating Weight: AZ30–AZ275 g/m² (AZ150/AZ165 is the most widely used for construction).
Surface Treatment: Chromate passivation, anti-fingerprint, or oiled/unoiled options.
Quantity & Application: Monthly/one-time order quantity and usage scenario (e.g., roofing, home appliances, automotive parts).
