Frequently Asked Questions (FAQ)
-
Q: What is the difference between PE coating and PVDF coating?
A: PE (polyester) coating is a cost-effective option suitable for standard environmental conditions, offering good color retention and flexibility. PVDF coating provides higher chemical resistance and UV stability, but at a higher cost. For roofing applications, PE coating is widely used and is reliable in most climates. -
Q: Can this coil be used for both roofing and wall cladding?
A: Yes, this pre-painted galvanized steel coil is versatile and can be used for roofing, wall panels, ceiling tiles, and other architectural applications. The 0.45mm thickness is ideal for light-gauge metal roofing profiles. -
Q: What colors are available?
A: We offer a full range of RAL colors, including popular shades like RAL 3000 (red), RAL 5005 (blue), RAL 7016 (anthracite grey), and RAL 9002 (white). Custom color matching is available for orders with sufficient quantity. -
Q: How is the coil packaged for export?
A: Each coil is wrapped with multiple layers of protective materials: first a layer of plastic film, then waterproof kraft paper, and finally steel strapping with edge protectors. Wooden pallets or steel frames are used for secure stacking, suitable for sea freight. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 1 coil (approximately 3-5 tons). For trial orders, we can accept smaller quantities, subject to negotiation. Please contact our sales team for details. -
Q: Do you provide samples?
A: Yes, we offer free samples of A4 size or small pieces (shipping costs may apply). Samples can be sent within 3-5 working days after request. -
Q: What is the lead time for production?
A: For standard colors and sizes, the lead time is typically 15-20 days after order confirmation. For custom colors or special requirements, it may be 20-25 days. We always try to expedite urgent orders. -
Q: How do you ensure the coating thickness is uniform?
A: We use advanced coating machines with precise roller gap control and online coating thickness gauges. Every coil is inspected with a dry film thickness meter before shipment, and we provide test reports upon request.
