Product Features & Advantages
- Superior Corrosion Protection – The hot-dip galvanized substrate provides a robust zinc layer, while the PE paint coating adds an extra barrier against moisture, UV rays, and chemical exposure.
- Excellent Formability – With thickness ranging from 0.3mm to 1.2mm, the coil can be easily cut, bent, roll-formed, or stamped without cracking or peeling.
- Vibrant Color Options – Available in a wide spectrum of RAL colors and custom shades, ensuring aesthetic flexibility for architectural projects.
- Consistent Thickness Tolerance – Our coils are manufactured with precise gauge control, meeting the strict requirements of ASTM A755 for both flatness and dimensional accuracy.
- Durable PE Coating – The polyester paint system offers good flexibility, adhesion, and weather resistance, making it suitable for both indoor and outdoor applications.
- Lightweight yet Strong – Compared to solid metal sheets, pre-painted steel reduces weight while maintaining structural integrity, lowering transportation and installation costs.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between PE coating and PVDF coating?
A: PE (polyester) coating offers good flexibility and cost-effectiveness for general applications like roofing and wall panels. PVDF (polyvinylidene fluoride) provides superior UV resistance and color longevity but is more expensive. Our PE coated coils are ideal for standard projects where budget and performance are balanced. -
Q: Can I get custom colors or a specific RAL code?
A: Yes, we support a wide range of RAL colors and can also match custom samples. Please provide the color code or a physical sample before production, and we will confirm the coating. -
Q: Is the coil suitable for outdoor use in harsh climates?
A: Absolutely. The hot-dip galvanized substrate provides excellent corrosion resistance, and the PE top coat is formulated to withstand UV exposure, rain, and temperature variations. For extreme coastal or industrial environments, we recommend a higher zinc coating weight or optional PVDF coating. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 1 coil (approximately 3–5 tons) for common colors. For special colors or custom sizes, the MOQ may be higher. Please contact our sales team for specific requirements. -
Q: How do you ensure the quality of the coating?
A: We conduct multiple tests including T-bend, MEK rub, impact resistance, and salt spray test on each production batch. Our ISO9001 certified system ensures traceability and consistency. -
Q: What is the lead time for an order?
A: Typically 15–25 working days after order confirmation, depending on the quantity and color. Urgent orders can be expedited upon request. -
Q: Do you provide samples before bulk order?
A: Yes, we offer free A4 size samples (buyer pays shipping) for quality evaluation. Please contact us to request samples. -
Q: Can the coil be used for both interior and exterior applications?
A: Yes, the PE coating is suitable for both. For interior use, it provides a smooth, decorative finish; for exterior use, it offers reliable weather resistance. Always follow the manufacturer's recommendations for specific applications.
