Hemaokang Steel (Shandong) Co., Ltd. is pleased to supply premium zero spangle galvanized steel coil in DX52D D+Z grade, developed specifically for precision stamping and forming applications. Available in thickness from 0.3 mm to 3.0 mm and width from 900 mm to 1300 mm, this coil provides a clean, smooth, spangle-free surface that is free from zinc flower patterns. With excellent corrosion resistance and consistent mechanical performance, it is the right choice for manufacturers who value quality and efficiency in their stamping lines.
The following are the main features that make our zero spangle galvanized coil stand out:
- Zero Spangle Surface: Uniform and aesthetically clean surface, ideal for exterior panels, painted parts, and visible components.
- DX52D+Z Grade: The material is engineered for stamping, deep drawing, and intricate forming with fewer risks of cracking or tearing.
- Precise Thickness Control: Available in 0.3-3.0 mm with consistent thickness profile across the entire coil.
- Flexible Width Range: 900-1300 mm allows customers to select the best width for maximum material yield.
- Hot-Dip Galvanized Coating: Provides sacrificial corrosion protection, extending product life and reducing maintenance.
- Passivation and Oiling Options: Custom surface treatments protect the coil during storage and shipment, to be selected upon request.

Precision Stamping Advantages
Precision stamping relies on absolute repeatability and exact dimensional control. Our DX52D zero spangle galvanized steel coil is developed to minimize variation in thickness and mechanical properties, which translates into stable die filling and consistent stamping pressure. The zero spangle feature also prevents minor surface irregularities from transferring to stamped parts, preserving the surface quality of the final product. For complex parts with tight tolerances, the excellent ductility of DX52D ensures smooth bending, stretching, and flanging operations. This means fewer rejected parts, improved die life, and lower total production costs.
In addition, the uniform zinc coating offers reliable corrosion protection even after stamping. The coating is applied through a hot-dip galvanizing process, creating a metallurgical bond that resists peeling and flaking during forming. Some assembly processes require welding; our zero spangle galvanized coil can be welded with proper technique and standard precautions. If you require specific coating weights or special surface conditions, please contact our team for tailored solutions.
Customization and Packaging
We understand that every stamping project has unique requirements. The coil width can be trimmed to any size between 900 mm and 1300 mm; thickness can be selected from 0.3 mm to 3.0 mm. Coil inner diameter options include 508 mm and 610 mm, and other sizes may be available upon request. Coil weight can range from 3 to 8 tons, depending on your handling equipment. For export, the coils are secured with strict protective packaging: moisture-proof paper, steel straps, edge protection, and optional VCI (volatile corrosion inhibitor) film. All packaging is suitable for sea transportation from Qingdao Port.
Quality Assurance
We operate a comprehensive quality management system certified to ISO9001. Every production step is monitored, from raw material selection to final coil inspection. In-line gauges measure thickness and width in real time; surface inspection systems detect coating defects; and final testing confirms mechanical properties and coating weight. This ensures that every coil we ship meets the stringent standards required by precision stamping customers. Our qualified team also inspects edge quality and coil winding to avoid telescoping or damage during handling.
Frequently Asked Questions
Zero spangle refers to the surface of the galvanized coil where the zinc coating forms a uniform, matte texture without visible sparkling zinc crystals. This finish is achieved by controlling the solidification process during hot-dip galvanizing, providing a smooth surface that is ideal for painting and precision stamping.
DX52D is a low-carbon steel grade designed for cold forming and stamping. “D+Z” indicates that the coil is hot-dip galvanized with a zinc coating. This combination offers good ductility and corrosion resistance for pressed components.
Yes, thickness can be supplied within 0.3-3.0 mm and width within 900-1300 mm. Our production line is flexible to handle custom widths by slitting, and exact requirements should be discussed with our sales team for feasibility.
It is commonly used for precision stamping of automotive components, electrical enclosures, home appliance panels, brackets, and parts requiring a clean visible surface. The DX52D grade also supports moderate deep drawing.
Samples are available upon request. You can request a small sheared sample to evaluate surface quality and formability before placing a bulk order. A nominal sample fee may apply, which will be deducted from your first order.
Each coil is wrapped securely with moisture-resistant material and steel strapping, with edge protection. Packing types include horizontal or vertical, depending on container loading. Shipment is available from Qingdao Port, and we can arrange for sea, air, or land transportation.
Typical lead time for custom orders is about 2-4 weeks after the order confirmation and payment, depending on the specification and quantity. For standard sizes in stock, shipment can be arranged much faster.
Yes, our quality management system is certified under ISO9001. We also implement thorough internal inspection routines to maintain product consistency and reliability.
As a fast-growing exporter with an annual export value of US$50 million to US$100 million, Hemaokang Steel has supplied coils to markets across North America, South America, Europe, Southeast Asia, Africa, Oceania, the Middle East, and many other regions.
