Stainless steel products are more and more widely used. When processing these products, stainless steel pipes and stainless steel plates are often used. The use of stainless steel plates is relatively more, and with the increase of people's demand, the colors become more and more abundant, so what are the key points to buy colored stainless steel sheets
Point 1: Observe the metal surface
Since colored stainless steel plates
are mainly used for architectural decoration, the decorative appearance is particularly important. When consumers inspect products, they must strictly check whether there are problems such as color difference, scratches, trachoma, and surface watermark falling off.
Point 2: Determine the surface coloring process
The surface coloring process of stainless steel will affect the price. Water electroplating color: It gives people an unreal and imprecise feeling, just like spraying, it will also cause wastewater pollution, and the price is low. Vacuum plating coloring: relatively environmentally friendly, no toxic or polluting substances are produced, so the price is relatively high.
Point 3: The quality of the protective film of the stainless steel plate
A protective film is usually attached to the surface of the colored stainless steel plate to ensure the smoothness of the surface and avoid being scratched by hard objects. If a poor quality protective film is placed for a long time, it will appear powdery and difficult to tear, or a lot of glue will stick to the surface after tearing. During the inspection, it is recommended to tear a larger area to check the quality of the film.
Point 4: Determine the material
The commonly used color stainless steel plate
materials in the market are 201, 304, 316 and other models. Among these models, 316 has corrosion resistance, and the worst is 201, and the price difference is large. Therefore, some bad companies usually use 201 instead of 304 and 316. Some companies will use vacuum coating coloring process instead of vacuum ion coating coloring process, which will cause the surface to fade, rust and even crack. Stainless steel plates are installed in many architectural decoration projects. It can be found that the knowledge of buying stainless steel plates is still very rich. Following these aspects introduced above, especially in terms of stainless steel plate price manufacturers, we must be more vigilant to ensure that the price of the stainless steel plate purchased is reasonable and the quality is guaranteed.
