What is the difference between Weathering Steel red rust plate and common red rust plate?

With the rapid development of iron and steel industry, weathering steel has also been an unprecedented development opportunity. For some exposed buildings, such as bridges, railways and so on, they are widely used. In recent years, weathering steel with its own natural rust color, has been favored by many decoration industries, so what's the difference between Weathering Steel red rust plate and ordinary red rust plate? Let's get to know each other.

1. Different materials: weathering steel red rust plate is made of weathering steel, while ordinary red rust plate is made of ordinary steel.

2. The color is different: the color of ordinary steel plate is dark, which tends to be black red; the color of weathering steel red rust plate is bright.

3. Stability of rust layer: the corrosion of weathering steel red rust plate is a dense oxide film formed when it reacts with the atmosphere, which belongs to natural corrosion. It is tightly attached to the steel plate to prevent the atmosphere from reacting with the base layer, and it will not fall down if touched by hand; while the corrosion of ordinary red rust plate can be easily touched off when touched by hand, and it will be stained with the rust color on the hand, which will be used in the later stage of application The corrosion will occur more serious chemical corrosion after falling off.

4. Environmental protection: weathering red rust plate belongs to natural corrosion. According to different periods, its corrosion color will change differently, and it will not have any impact on the surrounding environment and ecology, so it is an ideal material for building decoration; ordinary red rust plate may be artificial corrosion after processing with chemical agent, which will not only affect the surrounding environment, but also the stability of the building itself Qualitative analysis is not guaranteed.
