Frequently Asked Questions (FAQ)
-
Q: What does G90 coating mean?
A: G90 refers to a zinc coating weight of 0.90 oz per square foot (total both sides) in accordance with ASTM A653. This provides a minimum average coating thickness of approximately 0.7 mils per side, offering good corrosion protection for structural applications. -
Q: Can I order other sizes besides 4x8 ft?
A: Yes, we accept custom sizes. Common alternatives include 4x10 ft, 5x10 ft, or custom lengths. Minimum order quantities may apply for non-standard sizes. Please contact us with your requirements. -
Q: Is this plate suitable for outdoor use in coastal areas?
A: G90 coating is generally suitable for moderate environments. For aggressive coastal or industrial environments, we recommend considering a heavier coating (e.g., G115 or G140) or additional protective paint. Please consult our technical team for site-specific recommendations. -
Q: What is the typical lead time for shipment?
A: For standard thickness and size (3-6mm, 4x8ft), lead time is usually 7-15 working days depending on order quantity. Custom processing may add a few extra days. We can discuss express options if urgent. -
Q: Can these plates be welded without damaging the coating?
A: Welding will remove the zinc coating in the weld zone, which should be repaired with cold galvanizing paint or zinc-rich primer after welding. Pre-galvanized plates can be welded using standard techniques; however, proper ventilation is required due to zinc fumes. -
Q: Do you provide mill test certificates (MTC)?
A: Yes, we provide a mill test certificate for each shipment, documenting chemical composition, mechanical properties, and coating weight test results as per ASTM A653. -
Q: What packaging do you use for export?
A: Plates are packed in steel bundles with protective wrapping and edge protectors. For sea freight, we use fumigated wooden crates or pallets as needed to ensure safe transportation. -
Q: How can I request a sample before bulk order?
A: Sample plates (e.g., 200x200mm) are available upon request. The sample is usually free, but shipping costs apply. Contact our sales team to arrange a sample order.
