Regular Spangle Galvanized Steel
Regular Spangle Galvanized Steel serves as the foundational product in the hot-dip galvanizing process. It features a naturally crystallized, snowflake-like zinc spangle coating that combines corrosion resistance, decorative appeal, and excellent workability.
Ensure product quality and transportation
Leveraging mature and stable production lines and processing equipment, Wanzhi Steel consistently supplies high-quality regular spangle galvanized steel coils, plates, and customized slit strips to meet diverse customer requirements.
How is the regular zinc spangle pattern formed on galvanized steel surfaces?
During production, as the base steel coil emerges from the molten zinc bath, the adhering molten zinc layer solidifies and crystallizes under controlled cooling conditions. This process creates the visible zinc spangle—a distinctive, lustrous snowflake-like pattern.

Features of Regular Spangle Galvanized Steel
- Aesthetic Spangle: The surface exhibits naturally uniform, snowflake-like zinc spangles with a metallic luster. The dense crystalline structure ensures the spangles are resistant to flaking, combining decorative appeal with protective properties.
- Superior Corrosion Resistance: The zinc coating provides reliable sacrificial anode protection for the steel substrate, effectively preventing rust. It delivers extended service life even in outdoor environments.
- Good Processability: Coils can undergo continuous deep processing such as roll forming, bending, and stamping. It is recommended to select substrates with good flexibility, such as DX51D.
- Economical and Practical: Compared to special zinc flower types like fine zinc flower or no zinc flower, conventional zinc flower galvanized steel has a mature production process and offers high overall cost-effectiveness.
Applications of Regular Spangle Galvanized Steel
- Coils: Primarily used in subsequent processing plants for continuous roll forming, cutting into flat sheets, and manufacturing ventilation ducts, cable trays, light steel studs, etc. Additionally serves as substrate for PPGI steel coils to meet higher decorative requirements.
- Sheets: Widely applied in construction sectors such as factory exterior walls, roofs, warehouse door panels; agricultural grain silos, greenhouse structures; General-purpose appliance housings and distribution boxes; automotive applications including fenders, fuel tank shells, and truck body side panels.
- Strips: Suitable for manufacturing narrow components like architectural hardware fittings and window/door frame reinforcement strips; fastening steel bands and decorative strips for home appliances; packaging steel straps and bundling bands.
Comparison of Conventional Zinc Flower with Other Zinc Flower Types
| Comparison Dimensions | Regular spangle galvanized steel | Small spangle galvanized steel | Spangle-free galvanized steel |
| Zinc Flower Morphology | Snowflake-like pattern, large and uniform crystals, clearly visible | Dense crystal structure, smooth surface | No visible zinc spangles, smooth and flat surface |
| Production Process | Natural crystallization, no additional treatment required | Other ingredients need to be added and the cooling rate needs to be controlled. | Adjusted zinc bath composition, special cooling process |
| Surface Aesthetics | Strong metallic luster, excellent natural decorative properties | Smooth surface, suitable for subsequent painting | Smoother surface, optimal coating adhesion |
| Cost Price | Low price, highest cost-performance ratio | Medium quality | Higher cost |
