1:观察基板厚度和覆膜的厚度
1: Observe the thickness of the substrate and the thickness of the film coating
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 a substrate and colored peritoneum or coating. We first need to consider the thickness of the substrate and peritoneal coating. A good color steel plate substrate is 0.02~0.05mm, while the thickness of the film or coating is often only below 0.15mm. Because from the perspective of affecting the service life of color steel plates, the thickness of the substrate is very important. However, some manufacturers of color steel plates often tamper with the substrate and color steel plate coating or film. They reduce the thickness of the substrate but increase the thickness of the peritoneum to reduce the production cost of color steel plates, which greatly reduces the service life of color steel plates.
2:观察彩钢板的外漏边缘
2: Observe the exposed edge of the 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。
After receiving a color steel plate, I first observe whether the exposed steel of the color steel plate, such as the cross-section, is finely crystallized, whether it is gray, dark, and has impurities. If the cut surface is crystalline and fine, it is of superior quality.
3:听声音
3: Listen to the sound
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。
Tap the colored steel plate with your fingers or a hard object. If the material of the colored steel plate is poor, the sound it produces will be muffled and the metallic sound will not be obvious. The metallic sound of the colored steel plate with better material is relatively loud and crisp.
4:查看彩钢板的质量合格证明
4: View the quality certificate of the 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。
Are there inspection standards from relevant departments. If possible, try to visit the manufacturer of color steel plates for on-site inspection. Check the environment of the enterprise and whether it is formal. Inquire about the reputation of this company in the market.
5:看
5: Check 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 gets what you pay for. When comparing the quality of color steel plates, price is one aspect, but we should not pay too much attention to it. If the price of a color steel plate is much lower than others, then we need to pay attention.
