This is the way to identify the quality of color stainless steel plate

There are so many ways to identify the quality of colored stainless steel plates, is there any trick? Come and come, Shuitianfu Stainless Steel will give you two tricks.

The first move is to look at the material.

The common materials of color stainless steel plate are 304 material, 304 calendering material, 201 material and 201 calendering material. Among them, the corrosion resistance of 304 stainless steel is better than that of 201 stainless steel, and the real material is flat and brighter than the rolled material. The resulting large price difference will allow unscrupulous merchants to charge shoddy products, use calendered material to charge genuine material, and use 201 to charge 304. The end result is that in just a few months, the color stainless steel plate begins to fade, rust and even crack. It can be seen that the first task of our inspection is to verify whether the material of the plate is consistent with the specified one. The real material and the calendered material are mainly distinguished by the quality of the board surface. The surface of the positive board is smooth and flat, the color is uniform, the brightness is high, and the thickness of the whole board is the same, while the surface of the calendered board is dark, the color is uneven, often black or striped, the reverse side has roller embossing, many blisters, peeling water marks If there are other defects, the thickness difference of the board surface can reach 2 to 3 C. However, with the advancement of the production process of many large-scale calendering plants, the gap between the real material and the calendered material is gradually narrowing, and even some imitation real material boards require experienced professionals to distinguish. As for 304 stainless steel and 201 stainless steel, stainless steel potion can be used to distinguish.

The second trick is to see the effect.

The color stainless steel plate is mainly used in the decoration field, and the ornamental and decorative requirements of the plate surface are relatively high. When inspecting the goods, be sure to check and observe carefully. A good color stainless steel plate should have no visible chromatic aberration under direct sunlight, uniform coloring, good color, no scratches, no fading after bending; stainless steel mirror panels should have no grinding flowers and horseshoe prints on the surface, and high brightness.
