How to distinguish weather resistant steel plate and ordinary steel plate

1. Corrosion resistance: weather resistant steel plates are corroded in natural climates, and a dense oxide layer is formed on the surface of the steel, which prevents oxygen and water in the atmosphere from penetrating into the matrix and plays a role in oxidation. When ordinary steel is corroded, not only it will not be protected by the oxide layer, but the corrosion will be more serious.

2. Corrosion will not fall off naturally: the rust of weather resistant steel plate is a naturally formed rust, which is tightly attached to the surface of the base layer, even if it is touched by hand, it will not fall off. Ordinary steel, even if the rust on the surface is the same as that of weather resistant steel plate, it will easily fall off when touched by hand, which can be easily distinguished with the naked eye.

3. The color of rust is natural: the rust of weather resistant steel plate shows different colors according to the degree of corrosion and time, and these colors are oxidized by iron ions in the steel, so the rust will not cause damage to the surrounding ecology and environment. Ordinary steel is painted in order to have the same appearance as weather resistant steel plate. Even if the color is the same, the paint itself is a chemical synthetic agent with a pungent odor and has a certain impact on the surrounding ecology.

In summary, weather resistant steel plates and ordinary steel plates can be easily distinguished. Weather resistant steel plates have been widely used in many construction industries. In recent years, weather resistant steel plates have also developed well in the direction of container transportation, so their prospects are still relatively broad.
