For the current construction market, there are many new types of building materials, but the diversity of color steel plate makes it gradually become a popular choice. It is important that it can meet people's needs in all aspects. As people's requirements for building materials are higher and higher, so people should pay attention to the quality of building materials when they buy them. Therefore, it is very important to learn how to judge the quality.

观察基材的厚度和涂层的厚度：彩钢板由基材和彩色腹膜或涂层组成。我们需要考虑衬底的厚度和腹膜涂层。较好的钢基板为0.02~0.05mm，涂层或涂层的厚度通常小于0.15mm。基板的厚度在影响色板使用的时间上是非常重要的。一些衬底上的彩钢板通常是和彩钢板层或层压，减少基板的厚度，但是腹膜的厚度增加到减少彩钢板的生产成本，这大大减少彩钢板的使用寿命。

Observe the thickness of the substrate and the thickness of the coating: the color steel plate is composed of the substrate and color peritoneum or coating. We need to consider the thickness of the substrate and the peritoneal coating. The better steel substrate is 0.02 ~ 0.05mm, and the thickness of coating or coating is usually less than 0.15mm. The thickness of the substrate is very important in affecting the use time of the color plate. The color steel plate on some substrates is usually laminated or laminated with the color steel plate to reduce the thickness of the substrate, but the thickness of the peritoneum increases to reduce the production cost of the color steel plate, which greatly reduces the service life of the color steel plate.

观察彩钢板的泄漏边缘：当拿到一块彩色钢板时，观察外露的钢，如断面，是否结晶细，灰色，深色和杂质。如果切割面是晶莹剔透的，质量就更好。

Observe the leakage edge of color steel plate: when getting a piece of color steel plate, observe the exposed steel, such as cross section, for fine crystallization, gray, dark color and impurities. If the cutting surface is crystal clear, the quality is better.

听：用手指或用好东西敲打彩钢板，彩钢板材质如果是坏的，声音是沉闷的、金属声音不明显，好的色钢板金属声音响亮而清晰。

Listen: hit the color steel plate with your finger or with a good thing. If the color steel plate material is bad, the sound is dull and the metal sound is not obvious. The sound of good color steel plate is loud and clear.

总而言之，彩钢板属于一种新型建筑材料，具有良好的功能，被广泛应用于屋面、墙体、临时房屋等方面。

In a word, color steel plate is a new building material with good environmental protection function, which is widely used in roof, wall, temporary housing and so on.
