Frequently Asked Questions (FAQ)
Q1: What does G250 and AZ150 mean in G250 Az150 Aluzinc Galvalume Steel Coil?
A: G250 refers to the grade of the cold-rolled substrate, meaning the minimum yield strength is 250 MPa. AZ150 refers to the coating weight, meaning the total 55% Al-Zn-Si coating weight per square meter is 150 grams (both sides combined).
Q2: Can the coating weight of G250 Az150 Aluzinc Galvalume Steel Coil be customized?
A: Yes. While AZ150 is the standard coating weight, we can customize it to AZ100, AZ120, AZ200, or AZ275 according to your project's corrosion resistance requirements, especially for harsh environments like coastal areas.
Q3: Is G250 Az150 Aluzinc Galvalume Steel Coil suitable for welding and bending?
A: Absolutely. The G250 grade substrate ensures good ductility, and the AZ150 coating has excellent adhesion, allowing easy welding, bending, stamping, and cutting without coating peeling. We can provide technical guidance for processing.
Q4: What is the minimum order quantity (MOQ) for G250 Az150 Aluzinc Galvalume Steel Coil?
A: The standard MOQ is 25 tons (one full coil). For trial orders or small projects, we can negotiate MOQ of 10–25 tons based on current inventory and production schedule.
Q5: What is the lead time for G250 Az150 Aluzinc Galvalume Steel Coil orders?
A: For standard specifications, the production lead time is 15–20 days after deposit confirmation. For customized specifications, lead time is 20–25 days. Urgent orders can be arranged within 10–15 days if materials are in stock.
Q6: Does G250 Az150 Aluzinc Galvalume Steel Coil require surface treatment before painting?
A: No. The AZ150 coating has excellent paint adhesion, so it can be directly painted without additional surface treatment. For better paint durability, we can provide chromated or anti-fingerprint (AFP) surface treatment upon request.
Q7: What packaging is used for G250 Az150 Aluzinc Galvalume Steel Coil for export?
A: Standard export packaging includes waterproof kraft paper + PE plastic film + metal strapping with edge protectors, ensuring the coil is protected from moisture, dust, and damage during sea or land transportation. Custom packaging (such as wooden pallets) is available.
Q8: Does GNEE STEEL provide samples of G250 Az150 Aluzinc Galvalume Steel Coil?
A: Yes. We offer free samples (1–2 meters per sample) for quality testing. The sample lead time is 3–5 days, and customers only need to bear the shipping cost. We can also provide detailed test reports with the samples.
