How to correctly choose a good quality color stainless steel decorative plate?
1. distinguish the material
In this era of serious homogenization, the commonly used materials of colored stainless steel plates on the market today are also the most circulating models, such as 201, 304, 316, and so on, which are processed by various coloring processes. Among these materials, the best corrosion resistance is 316, and the worst is 201, and the difference in price is also relatively large. Bad enterprises in the industry often use industrial 201 stainless steel with poor material to replace food-grade stainless steel 304 and 316. When installing stainless steel plates in many building decoration projects, the surface has the problem of color falling off, rust and even fracture, so the selection of stainless steel should be clear whether its material is 201 or 304.
2. surface coloring process
Stainless steel surface coloring process will affect the price of high and low, the production of stainless steel decorative plate is the stainless steel plate or stainless steel products through chemical or electrochemical treatment, so that the surface of the formation of a layer of conversion film, blue, gold, rose red, green and a series of colorful colors, while increasing the corrosion resistance and wear resistance of stainless steel products. Therefore, to understand whether the surface coloring process is passed, mainly look at the plating time, in theory, the longer the plating time, then the coating of colored stainless steel is not so easy to fade, of course, but also to see how the color of electroplating is, whether it can meet the requirements of your imagination, which is to see the third point!
3. Observe the metal surface
Because the color stainless steel plate is mainly used for architectural decoration, it is very important for viewing. When the owners inspect the goods, they need to close it, carefully inspect and observe the surface to see if there are color differences, as well as problems such as nail holes, scratches, trachoma, peeling water marks.
4. the quality of the film
After processing, a protective film is usually attached to the surface of the colored stainless steel plate to ensure the surface finish and avoid scratches by hard objects. Poor quality protective film, put for a long time, will appear powder phenomenon, difficult to tear, or tear on the surface will stick to a lot of glue, unwatchable. When inspecting goods, it is recommended to tear a larger area to check the quality of the film, and after the installation of the decoration project, tear off the film as soon as possible, especially for outdoor decoration.
