Hemaokang Steel (Shandong) Co., Ltd., established in 2025 with an annual export value of US$50-100 million, is proud to offer the 1.0mm DX51D+Z Galvanized Steel Coil in 1000mm width with Z180 coating – a premium solution designed specifically for roofing applications. Our ISO9001-certified production line ensures consistent quality, tight tolerances, and excellent corrosion resistance, making this coil a reliable choice for contractors, building material distributors, and construction projects worldwide. With a dedicated team of 51-100 employees and a strong export presence across North America, South America, Europe, Africa, Oceania, and Asia, we deliver both standard and customized coils to meet your exact requirements.
This galvanized steel coil is manufactured from DX51D+Z grade steel, which offers good formability and weldability. The Z180 zinc coating (180 g/m² total both sides) provides superior protection against rust and atmospheric corrosion, extending the lifespan of roofing panels. The 1.0mm thickness and 1000mm width are optimal for producing profiled sheets, standing seam roofs, and other roofing components. Every coil undergoes strict quality checks – from substrate inspection to coating weight verification – ensuring you receive a product that meets international standards.
Key Features & Technical Specifications
- Material Grade: DX51D+Z (EN 10346 equivalent) – excellent for bending, profiling, and stamping.
- Thickness: 1.0 mm (±0.05 mm tolerance) – consistent across the entire coil.
- Width: 1000 mm (customizable from 900mm to 1250mm upon request).
- Zinc Coating: Z180 (180 g/m²) – provides long-term protection in outdoor environments.
- Surface Finish: Regular spangle, minimized spangle, or zero spangle (optional).
- Coil Weight: Typically 3–8 tons per coil, customizable to meet shipping and handling needs.
- Inner Diameter: 508 mm or 610 mm – standard options available.
- Application: Suitable for roofing sheets, wall panels, gutters, and other building components.

Product Advantages & Benefits
- Excellent Corrosion Resistance: The Z180 zinc coating acts as a sacrificial layer, protecting the steel substrate from rust and extending the roof’s service life in humid or coastal environments.
- Superior Formability: DX51D+Z material allows easy bending, cutting, and profiling without cracking – ideal for creating complex roofing profiles.
- Consistent Dimensional Accuracy: Our advanced production lines ensure thickness and width tolerances are maintained within ±0.05mm and ±2mm respectively, reducing waste during installation.
- Cost-Effective Solution: Compared to other corrosion-resistant materials like stainless steel or aluminum, galvanized steel offers a favorable balance of strength, durability, and affordability.
- Eco-Friendly: Galvanized steel is 100% recyclable, contributing to sustainable building practices.
- Flexible Customization: We offer various coating weights (Z100–Z350), surface finishes, coil sizes, and packaging options to match your specific project needs.
Frequently Asked Questions (FAQ)
-
What is the minimum order quantity (MOQ) for this galvanized coil?
Our standard MOQ is 25 tons per specification. However, we can accommodate smaller trial orders (e.g., 5–10 tons) for new customers. Please contact our sales team for details. -
How long does delivery take?
For standard specifications, production takes 15–20 days after order confirmation. Shipping time depends on the destination – typically 25–40 days by sea. We also offer expedited production for urgent orders. -
What packaging is used to protect the coil during transport?
Each coil is wrapped with waterproof paper, plastic film, and steel straps. Additional wooden crates or pallets are available upon request to prevent damage during long-distance shipping. -
Can you provide a mill test certificate or quality report?
Yes, we provide a Mill Test Certificate (MTC) per ISO 9001 for each batch, including chemical composition, mechanical properties, and coating weight test results. Third-party inspection (e.g., SGS, BV) is also available at extra cost. -
Is this coil suitable for use in coastal areas with high salt exposure?
For coastal environments, we recommend a higher zinc coating weight such as Z275 or Z350. The Z180 coating offers good protection for inland and moderate atmospheres, but for severe salt exposure, please consult our technical team for a customized recommendation. -
Can I get a small sample before placing a bulk order?
Certainly. We can provide free samples (A4 size or 30cm x 30cm) with you covering the shipping cost. This allows you to test the material’s formability, coating adhesion, and surface quality. -
Do you offer custom widths or coatings other than Z180?
Yes, we can produce coils in widths from 900mm to 1250mm and coating weights from Z100 to Z350. Special surface finishes like anti-fingerprint or chromate-free are also available. Contact us with your specifications. -
What payment terms do you accept?
We typically accept T/T (30% deposit, 70% before shipment) or L/C at sight. For long-term partners, other terms may be negotiable. We also work with trade assurance to protect your payment.
