What is the difference between corten A plate and ordinary steel plate

With the development of iron and steel industry, the demand for steel in many construction industries has gradually changed from quantity to quality. For some open-air buildings, if ordinary steel plates are used, they will be full of rust in a few years. Even if they are painted for protection, they will also damage the surrounding environment and steel itself. At this time, the research and development of corten A plate has brought good solutions to these problems definitely.

In order to save production costs, many businesses are willing to use ordinary steel plate for painting and human work rust to cheat consumers. Let's see how to distinguish corten A plate and ordinary steel plate.

1. Corrosion resistance: corten A plate is corroded in natural climate. It is a dense oxide layer formed on the steel surface, which prevents oxygen and water in the atmosphere from infiltrating into the matrix and plays an oxidation role. However, ordinary steel will not be protected by oxide layer after rusting, but will be corroded more seriously.

2. Corrosion will not fall off naturally: corten A plate corrosion is naturally formed corrosion, which is closely attached to the surface of the base layer, and will not fall off even if it is touched by hand; while corten A plate forged by ordinary steel, even if the surface corrosion is the same as corten A plate, it will fall off easily if it is touched by hand, which can be easily distinguished by the naked eye.

3. Natural corrosion color: corten A plate corrosion presents different colors according to corrosion degree and time, and these colors are presented by iron ion oxidation in steel, so the corrosion will not cause damage to the surrounding ecology and environment; In order to have the same appearance as corten A plate, ordinary steel has been painted. Even if it has the same color, the paint itself is a chemical synthetic agent, which has a pungent smell and has a certain impact on the surrounding ecology.

To sum up, corten A plate and ordinary steel plate can be easily distinguished. If you can't distinguish them, you can choose a reputable corten A plate manufacturer to purchase, so as to avoid unnecessary losses caused by being cheated. Corten A plate has a wide range of applications in many construction industries, and also has a good development in the direction of container transportation in recent years, so its prospects are still relatively broad.
