Regular Spangle Galvanized Steel, often referred to as spangle GI coil, is a high-quality cold-rolled steel substrate coated with a layer of zinc through a continuous hot-dip galvanizing process. This specific type of galvanized steel is characterized by its distinctive, visible crystalline pattern—the zinc spangle surface—which provides a classic metallic appearance alongside robust corrosion protection. It is a fundamental material for applications requiring durability and a traditional galvanized look. ChinaCNU Steel, with over 15 years of expertise, manufactures and exports premium Regular Spangle Galvanized Steel coils and sheets from our factory in Qingdao, serving industrial clients worldwide.
Our Regular Spangle Galvanized Steel is produced to meet international standards, offering a versatile range of specifications to suit various project requirements. The defining feature is the visible, medium-sized spangle pattern that forms naturally during the zinc solidification process.
| Grade | Thickness (mm) | Width (mm) | Zinc Coating (g/m²) | Standard |
|---|---|---|---|---|
| DX51D, DX52D, SGCC | 0.12 – 3.0 | 600 – 1500 | 60 – 275 | ASTM A653, EN 10346, JIS G3302 |
| Q195, Q235, SGC400 | 0.18 – 2.5 | 800 – 1250 | 80 – 220 | GB/T 2518 |
The combination of strength, formability, and corrosion resistance makes Regular Spangle Galvanized Steel a preferred choice across numerous sectors. Its classic spangle finish is both functional and aesthetically accepted in many industrial contexts.
When sourcing reliable regular spangle steel, partnering with a trusted manufacturer is crucial. ChinaCNU Steel provides a seamless supply chain and guaranteed quality.
Pricing for Regular Spangle Galvanized Steel is primarily determined by raw material costs (steel coil and zinc), thickness, coating weight, and international market trends. As a factory, ChinaCNU Steel offers highly competitive FOB Qingdao prices. We provide tailored quotations based on your specific technical requirements and volume.

The key difference lies in the visible surface pattern. Regular Spangle Galvanized Steel has a classic, medium-sized crystalline zinc spangle surface that is clearly visible to the eye, formed by natural zinc crystallization. Minimal spangle (or minimized spangle) steel undergoes a treatment to suppress crystal growth, resulting in a much finer, smoother, and more uniform appearance, which is often preferred for painting.
Yes, regular spangle galvanized steel can be painted, but surface preparation is critical. The pronounced spangle pattern may be slightly visible through thinner paint films. For optimal paint adhesion and finish, thorough cleaning and the use of a suitable primer designed for galvanized surfaces are essential. For applications requiring a perfectly smooth painted finish, minimal spangle or galvannealed steel is often recommended.
Choosing a regular spangle steel coil offers several advantages. It provides excellent corrosion protection at a competitive cost. The natural spangle pattern can be desirable for architectural or industrial applications where a traditional galvanized look is acceptable or even preferred without the need for painting. It also offers good formability and weldability for fabrication.
Our standard payment terms are T/T (Telegraphic Transfer) or L/C (Letter of Credit), ensuring a secure transaction for both parties. For export packing, we use industry-standard methods: coils are protected with waterproof paper and steel straps, while sheets are bundled on sturdy wooden pallets and wrapped in waterproof and steel-reinforced packing to prevent damage during long-distance shipping to destinations like Africa or South America.
