Since its birth 100 years ago, stainless steel plates have been widely used in all walks of life. Its smooth surface, good mechanical properties and stable chemical properties have made it an evergreen tree in the building materials industry. However, the quality of plates on the market varies, so what factors should we pay attention to when purchasing stainless steel plates?
1. Material
The most commonly used stainless steel plate materials on the market include 304, 201, 316 and other models. Among these models, 316 stainless steel has the best chemical and physical properties, and 201 has the worst. The quality and price of the stainless steel plates made of different materials vary widely. Some unscrupulous merchants will use 201 with poor material to replace 316 and 304 with good material. Therefore, when purchasing, we must not fall into the trap of unscrupulous merchants. "Low price trap", we should focus on the material and model.
2. Specifications of steel plate
The specifications of steel plates are a factor that must be considered when purchasing steel plates. Common specifications include length, width and thickness. Different thicknesses are suitable for different occasions and need to be selected according to the specific situation. Choosing a thickness that is too large or too small will affect the service life and performance of the steel plate.
3. Coloring process
There are two coloring processes for stainless steel plates. One is the water plating coloring process, which is low-priced, the effect is not realistic and refined enough, has a strong spray feel, is easy to fall off and rust, and causes environmental pollution; the other is the vacuum plating coloring process, which is more expensive and But the coloring effect is good, and there is no need to worry about falling off or causing other environmental pollution. Some unscrupulous businesses will use water plating process instead of vacuum plating. Such stainless steel plates are prone to color loss, rust and breakage during installation.
4. Steel plate surface
When purchasing stainless steel plates, you should observe the surface of the stainless steel plates to check whether there are color differences, blisters, peeling water marks, scratches and other surface defects that affect the aesthetics. While the material and craftsmanship of stainless steel plates is important, the surface appearance cannot be ignored either, as it will directly affect the effect of architectural decoration.
5. Film quality
After the stainless steel plate is processed, a protective film will be attached to the surface to prevent the steel plate from being scratched while maintaining the smoothness of the steel plate surface. However, if the protective film of poor quality is left for a long time, it will become powdery and difficult to tear off. Even after being torn off, there will be a lot of glue. Therefore, when we inspect the goods, it is best to tear off the protective film over a larger area for inspection. At the same time, the protective film must be removed as soon as possible after the project is completed.
6. Selection of steel plate manufacturers
The manufacturer of stainless steel plates is a very important factor. The quality of steel plates produced by different manufacturers is very different. Manufacturers with higher brand awareness and more advanced production processes generally produce better quality stainless steel plates. In order to avoid unexpected problems during future use, it is recommended to choose products from stainless steel plate manufacturers with a well-known and good reputation.
7. Pay attention to the quality certificate of the steel plate
The quality certificate of the steel plate is very important and is also the "ID card" of the steel plate. It can prove whether the steel plate meets the requirements, meets the standards and is qualified. When purchasing steel plates, be sure to confirm whether the quality certificate of the steel plates is true and valid, so as to avoid unnecessary problems during use.
Other notes:
In addition to the above points, you should also pay attention to the following matters when purchasing stainless steel plates:
1. Order quantity: The usage of the stainless steel plate must be taken into consideration to determine the order quantity of the steel plate to prevent the order quantity from being too small or too large, which will affect later use.
2. Transportation and storage: Choose the appropriate transportation method, properly reinforce the material of the steel plate, and store the steel plate reasonably.
In short, stainless steel plates are an indispensable material in current industrial production. When purchasing steel plates, you must pay attention to various parameters such as material, thickness, and specifications. At the same time, it is also necessary to pay attention to the surface quality of the steel plate, manufacturer, quality certificate, packaging and transportation and other information to avoid the negative impact of steel plate quality problems.

In actual procurement, you need to understand the requirements for actual use. If it does not meet the requirements, you must customize it or choose other steel plates that meet the conditions.
