Products advantages
| No. | Advantage | Description |
|---|---|---|
| 1 | Excellent Anti-Corrosion Performance | The zinc layer isolates the steel from external environments, preventing corrosion. This ensures a long service life even in harsh conditions (e.g., humidity, industrial atmospheres). |
| 2 | Good Processing Performance | High formability and weldability allow easy shaping into various sizes/forms. Ideal for manufacturing flexibility (e.g., stamping, bending). |
| 3 | Beautiful & Durable | Smooth, bright surface with decorative appeal. Resists discoloration and rust, maintaining aesthetics and durability over time. |
| 4 | Eco-Friendly & Energy-Saving | Production adopts energy-saving technologies, reducing emissions. Longevity cuts maintenance/replacement needs, lowering overall environmental impact. |
| 5 | Significant Economic Benefits | Cost-effective with long service life and minimal maintenance. Reduces lifecycle costs in construction, automotive, and appliances. |
Classification of spangle
In the process of hot-dip galvanizing, the formation of zinc flowers is related to various factors, resulting in different shapes. According to different characteristics, zinc flowers can be classified into the following types: ordinary zinc flowers, fine zinc flowers, zinc free flowers, and special shaped zinc flowers. Ordinary zinc flowers are the most common type, with a larger shape and a more uniform distribution. Fine zinc flowers refer to those that are smaller in size and densely distributed. And zinc free products are hot-dip galvanized sheet coils with almost no visible zinc flowers on the surface under special process control. In addition, there are some special forms of zinc flowers, such as snowflake shaped zinc flowers in hexagonal star shape, as well as other complex forms of zinc flowers formed under specific conditions.
The classification of the national standard GB/T2518 is similar to that of the American standard. It is worth mentioning that Baosteel's enterprise standard Q/BQB420 mainly focuses on high-end galvanized products, so only one "zero zinc flower" is set up, which has a more detailed and specific definition compared to European and American standards.
In addition, there are detailed explanations about different sizes of zinc flowers: zinc flowers with a diameter greater than 3mm that can be distinguished by the naked eye are called large zinc flowers, and some people also call them normal zinc flowers or natural zinc flowers, with an optimal size range of 812mm; zinc flowers with a diameter of 12mm are called small zinc flowers; If the chemical composition of the zinc solution is controlled to make the zinc flower invisible to the naked eye on the surface of the board, it is called no zinc flower or zero zinc flower; Small zinc flowers or products without zinc flowers that have undergone the finishing process are called finished zinc flowers.
