How to choose high quality stainless steel color plate

We have already popularized the knowledge of stainless steel color plates, and with the popularization of stainless steel color plates, many unscrupulous merchants have shoddy and cut corners, which not only caused huge losses to many consumers, but also seriously damaged stainless steel. Market environment for colored plates. So how to choose high-quality stainless steel color plate? Topson has put together the following for you:

Identify the material of sheet metal materials

At present, the commonly used materials of stainless steel color plate Z in the market are 201, 304, 316 and other types of stainless steel coloring processing. Among them, the material with good corrosion resistance is 316, and the poor material is 201, and their prices are also quite different. Therefore, many businesses use 201 with inferior materials instead of 304 and 316.

Or use the water-plating coloring process instead of the vacuum ion-plating coloring process to sell stainless steel color plates to customers, so that many building decoration projects install color stainless steel titanium plates, mirror panels and other surface colors have faded, rusted or even is broken.

Therefore, during the purchase inspection process, it is necessary to be strict about whether the material of the plate is the original material, and the different materials of stainless steel can be distinguished by the detection potion.

Stainless steel surface coloring process

Similarly, the stainless steel coloring process is also one of the important factors in determining the price. The water plating coloring process obtains color due to the use of chemical solution immersion. Compared with the vacuum plating coloring process, the difference is that the bonding force between the vacuum electroplating coating film and the surface of the workpiece is stronger. Large, the hardness of the film layer is higher, the wear resistance and corrosion resistance are better, and the performance of the film layer is more stable, such as color stainless steel titanium plate, the golden yellow surface of the water-plated titanium plate gives the impression that it is just sprayed on; Vacuum plating coating does not produce toxic or polluting substances.

Water plating will cause waste water pollution. Compared with vacuum ion plating, the color is not so pure, and the phenomenon of shelling will occur, but the price is much cheaper than vacuum plating.

However, whether it is stainless steel color plate material or coloring process, it is generally difficult to distinguish from the naked eye. It requires professionals with rich experience to distinguish the quality of them. Therefore, when choosing to buy stainless steel color plate decorative materials, you must Find a professional and reputable processing factory to buy, don't delay the decoration project for petty cheap.

look at metal surfaces

One of the main uses of stainless steel color plates is for building decoration and decoration projects, and the decorative ornamentation of its surface is particularly important. When inspecting the goods, it is necessary to carefully inspect and observe the surface to see if there are defects such as color difference, uniform coloring, good color, scratches, sand holes, peeling water marks, etc. between the plates. Especially for titanium plates, etc., the surface is a mirror effect. If the quality is good, the surface should be free of grinding head flowers and horseshoe prints, and the brightness is high. Of course, the price will be relatively high.

film quality

After the stainless steel color plate product is processed, a layer of protective film should be attached to the surface. This layer of film can ensure that the surface finish will not be polluted, or protect it from scratching hard objects. However, if the poor-quality protective film is left for a long time, it will become powdered, and it will be difficult to tear it or a lot of glue will stick to the stainless steel surface after tearing, making the metal surface not only unsightly but also difficult to remove.

When inspecting the goods, the customer can tear off a relatively large area to check the quality of the film; and after the installation of the decoration project is completed, the film should be torn off as soon as possible, especially for the outdoor decoration project, the film should be torn off immediately after the installation.
