Up to now, stainless steel plates have existed for more than 90 years. Its surface is smooth, has good plasticity, toughness and mechanical strength, and is also resistant to corrosion by acids, alkaline gases or solutions. Stainless steel plates mainly refer to steel plates that are resistant to corrosion by weak media such as atmosphere, steam and water. How should consumers choose between products of varying quality on the market?
Stainless steel products include stainless steel plates, stainless steel coils, stainless steel tubes and stainless steel profiles, etc.
1. Distinguish the material
Commonly used materials for colored stainless steel plates on the market include 201, 304, 31 and other models, which are processed and colored. Among these models, the one with the best corrosion resistance is 316, while the worst is 201, and the price difference is also relatively large. Therefore, some unscrupulous dealers often use 201 with poor material instead of 304 and 316. Some use water plating coloring process instead of vacuum ion plating coloring process, which causes the color to fall off and rust on the surface when installing stainless steel plates in many building decoration projects. Problems with rust or even breakage
2. Surface coloring process
The stainless steel surface coloring process will affect the price. There are two main types: water plating coloring process and vacuum plating coloring process. The former gives people an unreal and unrefined feeling, like it was sprayed on, and will also produce wastewater pollution. The price lower. The latter is relatively environmentally friendly and does not produce toxic or polluting substances.
3. Observe the metal surface
Since colored stainless steel plates are mainly used for architectural decoration, their ornamental properties are very important. Owners need to be careful when inspecting goods, carefully inspect and observe the surface to see if there are any color differences, scratches, blisters, peeling water marks and other problems.
4. The quality of the film
After the processing is completed, a protective film is usually affixed to the surface of the colored stainless steel plate to ensure the smoothness of the surface and avoid scratches by hard objects. If the protective film of poor quality is left for a long time, it will become powdery and difficult to tear off, or a lot of glue will stick to the surface after being torn off, which is unsightly. When inspecting the goods, it is recommended to tear off a larger area to check the quality of the film, and to remove the film as soon as possible after the installation of the decoration project, especially for outdoor decoration.
