How to distinguish authenticity between corten sheet metal

Corten sheet metal is added copper, nickel and other alloy elements during smelting. When the corten sheet metal contacts with the atmosphere, a dense oxide layer is formed on the surface of the substrate, which prevents the corten sheet metal from further corrosion. It takes a long time to form the layer corrosion under natural conditions. With people's pursuit of art, corten sheet metal is formed. Corten sheet metal is also gradually applied in the field of design and decoration. How can we distinguish corten sheet metal?

1. Simpler is that is not hurry to buy when the sample comes to hand. If you take a picture of the sample and put it outdoors for a period of exposure and rain testing, you can see it.

2. Divide the sample into two parts. The original rust surface is destroyed by grinding machine or sandpaper in half, and then the watering observation is carried out. Because the real corten sheet metal is better, so even if a layer is knocked off, it will naturally grow good rust inside. The  lmitation doesn't work well. The side notes are just superficial.

3. It can be sent to a special inspection institution for inspection. The true corrosion of corten sheet metal is formed naturally, and its corrosion will change color with the increase of time. The imitation corrosion of corten sheet metal is formed by chemical reagent corrosion, which also has serious harm to human body and the surrounding environment.

Corten sheet metal is widely used in many industries, so some bad businessmen begin to manufacture counterfeit and inferior products, and make greater profits from them. Above is the method of distinguishing corten sheet metal. If you learn the above methods, you can reduce the probability of purchasing counterfeit products. When used in buildings, you can also reduce the occurrence of some potential safety hazards. The corten sheet metal provided by BBN steel is reliable in quality. If you need it, please contact us.
