Large | Big Spangle Galvanized Steel Sheet & Coil

Compared with other products on the market, our zinc flower galvanized steel has been improved in many aspects. First of all, we have strict control over the composition and thickness of the zinc layer to avoid uneven thickness of the coating, which not only ensures the beauty but also improves the protective performance of the whole plate. The unique texture of the zinc flower itself comes from the precise control of the cooling speed and the composition of the zinc liquid, which not only improves the decorative effect, but also provides consistent and efficient protection for the galvanized layer. In terms of processing adaptability, our zinc flower galvanized steel has high adhesion and is not prone to peeling or damage of the coating, so it can still maintain its good protective effect even after complex processing processes. This feature is particularly suitable for manufacturing projects that require bending, stamping and other processes to ensure that the material is durable and beautiful during use.

Industries & Applications

Construction industry: used for building materials such as roofs, walls, fences, rolling doors, etc., with good anti-corrosion performance and decorative effects.
Home appliance shell: such as refrigerators, washing machines, microwave ovens and other home appliances shell materials, both rust-proof and beautiful.
Automobile manufacturing: used for automobile chassis, body parts, interior and exterior trim, etc., to improve corrosion resistance and durability.
Agricultural equipment: used for agricultural equipment such as greenhouse frames and grain storage facilities, providing long-term anti-corrosion protection.
Infrastructure: used for bridges, street light poles, cable trays, etc., to meet the anti-corrosion needs in outdoor environments.
Furniture manufacturing: used in steel furniture such as filing cabinets and lockers, providing strong and rust-proof characteristics.
Industrial equipment: suitable for ventilation ducts, storage tanks, industrial pipelines, etc., to extend equipment life and reduce maintenance costs.

Other Infomation

Large/Big Spangle: Large spangle has obvious natural texture and beautiful appearance. It is suitable for decorative occasions such as building exterior walls and roofs, and has excellent anti-corrosion performance. However, due to the uneven surface, it may not be suitable for processing applications with high thickness consistency requirements.

Regular Spangle: Regular spangle has moderate texture and natural surface effect without exaggeration. It is suitable for applications such as construction and light industry that do not require further processing. It has certain decorative and anti-corrosion properties and is suitable for a wide range of scenarios, but the surface finish is not as good as small spangle and smooth non-spangle.

Small/Mini Spangle: The surface is more uniform and suitable for secondary processing such as painting. It is often used in products that require smooth surfaces such as furniture and home appliances. However, the decorative effect is not as obvious as large spangle.

Zero Spangle: No texture, smooth surface, suitable for applications with high surface requirements such as automobiles and home appliances, with excellent coating adhesion. However, the anti-corrosion performance may be slightly inferior to large spangle and has no decorative effect.

Does galvanized steel resist corrosion from acid rain or industrial pollution?

Yes, the zinc layer of galvanized steel is effective in resisting corrosion from acid rain and mild industrial pollution, and is suitable for use in mildly polluted environments. If the environment is more severe, we can also provide products with further enhanced corrosion resistance.

Can galvanized steel with different zinc layer thicknesses be customized?

Of course, we can customize different zinc layer thicknesses according to specific application requirements to ensure the ideal protection effect in different environments and usage conditions, and provide a more durable option.

Will the surface of galvanized steel change over time?

Due to the natural characteristics of the zinc layer, galvanized steel may slightly oxidize over time, but this usually does not affect its protective properties. Our products remain beautiful and durable for a long time in outdoor conditions.

How does SteelPRO Group ensure the environmental friendliness of its products?

We use environmentally friendly electroplating and waste recycling systems in our production process to reduce the impact on the environment.
