Color steel plate refers to color coated steel plate. Color coated steel plate is a kind of steel plate with organic coating. Color steel plate is divided into single plate, color steel composite plate, floor bearing plate, etc. It is widely used in the walls and roofs of large-scale public buildings, public workshops, movable plank houses and integrated houses.

1：观察基板厚度和覆膜的厚度

1: Observe the thickness of substrate and film

彩钢板是有基板和彩色的腹膜或者镀层构成的。我们得考虑基板和腹膜镀层的厚度，比较好的彩钢板基板是0.02~0.05mm，覆膜或者涂层厚度往往只有0.15mm以下。因为从影响彩钢板的使用时间来看，基板的厚度是很重要的。而有些生产彩钢板的厂家往往在基板及彩钢板涂层或覆膜上做手脚，他们降低基板的厚度，但是增加腹膜的厚度来降低彩钢板的生产成本，这就大大降低了彩钢板的使用寿命了。

Color steel plate is composed of base plate and color peritoneum or coating. First of all, we have to consider the thickness of the substrate and the peritoneum coating. A better color steel plate substrate is 0.02-0.05mm, and the coating or coating thickness is usually less than 0.15mm. Because the thickness of the base plate is very important in terms of the use time of the color steel plate. However, some manufacturers of color steel plate often make hands and feet on the substrate and the coating or film of color steel plate. They reduce the thickness of the substrate, but increase the thickness of the peritoneum to reduce the production cost of color steel plate, which greatly reduces the service life of color steel plate.

2：观察彩钢板的外漏边缘

2: Observe the leakage edge of color steel plate

拿到一块彩钢板，我先观察彩钢板外露钢材如断面等是否结晶细密，是否发灰、发暗和杂质。若切面是结晶细密型的则是质量比较优越的。

When I get a color steel plate, I will first observe whether the exposed steel of color steel plate, such as cross section, is crystallized and dense, grey, dark and impurity. If the section is crystal fine, the quality is better.

3：听声音

3: Listen to the voice

用手指或用硬物敲击彩钢板，彩钢板的材质如果较差，则发出来的声音是闷的，金属声音不明显，材质较好的彩钢板金属声音是比较响亮、清脆的。

Use your fingers or hard objects to knock on the color steel plate. If the material of color steel plate is poor, the sound is dull, the metal sound is not obvious, and the metal sound of color steel plate with better material is loud and clear.

4：查看彩钢板的质量合格证明

4: Check the quality certificate of color steel plate

是否有相关部门的检验标准。如果有可能的话尽量去彩钢板的生产厂家实地考察。看看企业的环境怎么样，是否正规。市场上打听一下这个企业的口碑怎么样。

Whether there are inspection standards of relevant departments. If possible, try to visit the manufacturer of color steel plate. See how the environment of the enterprise is and whether it is formal. Ask about the reputation of this enterprise in the market.

5:看

5: look at the price

任何东西，都是一分钱一分货。我们在比较彩钢板质量的时候，是一方面，但是也不要太注重。如果一种彩钢板的别其他的低很多，那么我们就要有所注意了。

Everything is a penny a penny. When we compare the quality of color steel plate, the price is on the one hand, but we should not pay too much attention to the price. If the price of one kind of color steel plate is much lower than others, then we should pay attention to it.
