Today, stainless steel sheets have been around for more than 90 years. The surface is smooth, has good plasticity, toughness and mechanical strength, and is also resistant to corrosion by acids, alkaline gases or solutions. Stainless steel plate mainly refers to steel plate which is resistant to corrosion by weak medium such as atmosphere, steam and water. For the quality of the market is uneven, how should consumers choose? Let's follow the decoration home together The decoration network Xiaobian learns the learning skills of stainless steel plates.
One. Distinguish the material
The commonly used materials for color stainless steel plates on the market are 201, 304, 31 and other models, which are colored by processing. Among these models, the best corrosion resistance is 316, and the worst is 201, the price difference is also relatively large. Therefore, some black merchants often use 304 with poor material to replace 304 and 316. Some will use the water plating coloring process instead of the vacuum ion plating coloring process, which makes the surface of the building decoration and decoration project with color peeling off. Rust or even broken problem
2. Surface coloring process
Stainless steel surface coloring process will affect the price level, mainly water coloring process and vacuum plating coloring process. The former gives people an unreal, not delicate feeling, just like spraying, it will also produce pollution of wastewater, price Lower. The latter is relatively environmentally friendly and does not produce toxic or polluting substances.
3. Observe the metal surface
Since the color stainless steel plate is mainly used for architectural decoration and decoration, the ornamental is very important. When the owners check the goods, they need to take good care of them and carefully inspect and observe the surface to see if there is any color difference, as well as scratches, blisters, peeling water marks and other issues.
Fourth, the quality of the film
After the processing is completed, a protective film is usually applied on the surface of the colored stainless steel plate to ensure the smoothness of the surface and to avoid scratching by hard objects. If the quality of the protective film is not good, it will be powdered for a long time, it will be difficult to tear, or it will stick to a lot of glue on the surface after tearing, which is unsightly. When inspecting the goods, it is recommended to tear a large 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.
The above describes how the stainless steel purchase process, the business is unscrupulous, the probability of the owner being deceived is very high, should do the relevant work in advance, it is necessary to learn this knowledge in advance.
This type belongs to closed type. Has superior seal type and constructability, make with different colour. Maily used in temporary signal board, work site and advertising board, having three years`s weathering resistance. It is suitable for AL board and steel board.In the daytime with its bright colors play a clear role in the warning, at night or lack of light in the case of its bright reflective effect can effectively enhance people's ability to identify, see the target, causing alert, so as to avoid accidents, reduce Personnel casualties, reduce economic losses, become an indispensable road safety safety guards, has a clear social benefits.
