Hemaokang Steel (Shandong) Co., Ltd., established in 2025 with an annual export value exceeding US$50 million, is proud to present our premium DX51D Z180 Galvanized Steel Coil in thicknesses of 0.5–2.0mm and a fixed width of 1250mm, specifically engineered for roofing applications. As a trusted manufacturer located in Liaocheng, Shandong, China, we combine modern production capabilities with ISO9001-certified quality management to deliver coils that offer superior corrosion resistance, consistent mechanical properties, and excellent formability. Our coils are widely exported to over 15 global markets, including North America, Europe, Southeast Asia, and Africa, making them a reliable choice for contractors and roofing material suppliers worldwide.
This hot-dip galvanized steel coil is produced using advanced continuous galvanizing lines, ensuring a uniform zinc coating of Z180 (180 g/m² total both sides) that provides long-lasting protection against rust and environmental exposure. The DX51D grade offers excellent ductility, allowing for easy bending, profiling, and stamping without cracking—ideal for roof panels, corrugated sheets, and other roofing profiles. With a thickness range from 0.5mm to 2.0mm, our coils accommodate various load-bearing requirements, while the standard 1250mm width minimizes material waste during shearing and forming processes.

Frequently Asked Questions (FAQ)
-
Q: What is the tolerance on thickness for DX51D Z180 coils?
A: For thickness ≤1.0mm, tolerance is ±0.05mm; for thickness >1.0mm up to 2.0mm, tolerance is ±0.08mm. These values meet EN 10143 and ASTM A653 standards. -
Q: Can you slit the coil into narrower widths?
A: Yes, we offer slitting services to produce custom widths down to 100mm, with tight tolerances. Please specify your required width when ordering. -
Q: How is the zinc coating weight measured? Is it total both sides?
A: Z180 indicates 180 g/m² total (both sides combined), measured by triple spot test according to ASTM A90. This is equivalent to G90 in the U.S. standard. -
Q: What is the minimum order quantity (MOQ) for this product?
A: Our standard MOQ is 25 tons per size. For trial orders, we may accept 10–15 tons, subject to negotiation. -
Q: Do you provide spangle-free (zero spangle) finish?
A: Yes, zero spangle finish is available upon request. Please note that minimal spangle may still appear on the surface due to process variations. -
Q: What packaging is used for export shipments?
A: Each coil is wrapped with waterproof paper, sealed with plastic film, and secured with steel straps. Edge protectors are applied to prevent damage during transit. Wooden pallets or crates are optional. -
Q: Can you provide a mill test certificate (MTC) with each shipment?
A: Absolutely. We issue a comprehensive MTC for each batch, including chemical composition, mechanical properties, and coating weight test results, in compliance with ISO9001. -
Q: How long is the typical lead time for a 100-ton order?
A: Production lead time is 15–20 days after confirmation of order and receipt of deposit. Sea freight delivery depends on destination; we can provide estimated shipping times upon request.
