Frequently Asked Questions
-
Q1: What is the difference between Z275 and other coating grades?
Z275 means 275g/m² of zinc coating on both sides (total), which is a standard heavy-duty coating. It offers better corrosion resistance than lower grades like Z100 or Z180, while higher grades like Z450 are thicker but more expensive. Z275 is widely used for roofing in moderate to harsh environments. -
Q2: Can this sheet be used for residential roofing?
Yes, 0.47mm galvanized corrugated sheets are commonly used for residential roofs, especially in areas with moderate weather. The 7.5/10cm corrugation provides good water drainage and structural strength. -
Q3: Do you offer color-coated options?
Yes, we can supply pre-painted galvanized sheets (PE or PVDF coating) in various colors like red, blue, green, white, etc. Please specify the color code and required coating when ordering. -
Q4: What is the minimum order quantity (MOQ)?
Our standard MOQ is 50 tons for corrugated sheets. However, for trial orders or sample evaluation, we can accommodate smaller quantities (e.g., 5 tons) upon negotiation. -
Q5: How do you ensure the product quality?
We have a dedicated QC team that performs dimensional checks, coating thickness tests (magnetic gauge), corrugation profile inspection, and mechanical property tests. Each batch comes with a Mill Test Certificate. -
Q6: What is the packing method for export?
Sheets are packed in bundles with steel strapping, waterproof paper, and plastic film. For sea freight, we also add wooden pallets or crates if required. The standard packing is suitable for container shipping. -
Q7: Can you provide custom lengths and widths?
Absolutely. We can cut sheets to any length between 1m and 12m, and we offer widths of 750mm, 900mm, 1000mm, or custom widths as per your specification. Additional charges may apply for non-standard sizes. -
Q8: What is the lead time for this product?
For standard sizes and quantities, lead time is typically 15–25 days after confirmation of order. For large orders or custom specifications, please allow 25–35 days.
