Welcome to Hemaokang Steel (Shandong) Co., Ltd. As a reliable supplier of high-quality steel products, we are proud to introduce our 1.2mm Hot Dipped Galvanized Steel Coil DX51D+Z with Spangle Finish, specifically designed for the construction industry. With our company established in 2025 and an annual export value between US$50 million and US$100 million, we have quickly built a strong reputation for delivering consistent quality and competitive pricing. This galvanized coil combines excellent corrosion resistance, superior formability, and an attractive spangle finish, making it an ideal choice for roofing, wall panels, structural components, and other building applications.
Our product is manufactured using state-of-the-art hot-dip galvanizing technology, ensuring a uniform zinc coating that provides long-lasting protection against rust and environmental elements. The DX51D+Z grade offers excellent ductility and weldability, allowing for easy fabrication without compromising the coating integrity. The spangle finish not only enhances the aesthetic appeal but also serves as a visual indicator of coating quality. Whether you need a standard size or a customized dimension, we provide flexible solutions to meet your project requirements.

FAQ – Frequently Asked Questions
- What is the difference between DX51D+Z and DX51D+ZF? DX51D+Z stands for hot-dipped galvanized with pure zinc coating, while DX51D+ZF is zinc-iron alloy coating (galvannealed). The +Z type offers better corrosion resistance and spangle appearance, suitable for outdoor construction.
- Can I get a sample before placing a bulk order? Yes, we provide free samples (shipping cost may apply). Please contact our sales team for sample requests.
- What coating weight options are available? We offer coating weights from Z100 (100 g/m²) up to Z275 (275 g/m²). The optimal choice depends on your environmental conditions and required lifespan.
- Is the spangle finish uniform across the entire coil? Yes, our production process ensures consistent spangle formation. However, slight variations in crystal size are normal and do not affect performance.
- How long does the galvanized coating last? In typical atmospheric conditions, a Z275 coating can last 20–30 years before first maintenance. Actual lifespan depends on environment (e.g., coastal areas may require higher coating weight).
- Do you provide cutting or slitting services? Yes, we offer custom slitting and cutting to your required dimensions. Please specify your needs when ordering.
- What packaging is used for export? Coils are packaged with anti-rust paper, plastic film, and steel strapping to protect during sea freight. We also offer wooden pallets or crates upon request.
- Can I combine this coil with other products in one shipment? Absolutely. We handle mixed containers and can consolidate multiple steel products to optimize your logistics.
