彩钢夹芯板广泛用于大跨度厂房、仓库、办公楼、别墅、楼顶加层、冷库、商店、售货亭和临时用房等方面，在本文教下大家怎样来判断它的质量好坏？
Color steel sandwich panels are widely used in large-span factories, warehouses, office buildings, villas, roof adding floors, cold storages, shops, kiosks and temporary houses. In this paper, how can we judge its quality?
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 coating
我们得考虑基板和腹膜镀层的厚度，比较好的夹芯板基板是0.02~0.05mm，覆膜或者涂层厚度往往只有0.15mm以下。因为从影响夹芯板的使用时间来看，基板的厚度是很重要的。而有些生产夹芯板厂家往往在基板及夹芯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夹芯板的生产成本，这就大大降低了彩钢板的使用寿命了。
We must first consider the thickness of substrate and peritoneal coating. A better sandwich plate substrate is 0.02 ~ 0.05mm, and the thickness of coating or coating is often less than 0.15mm. Because the thickness of the substrate is very important in terms of affecting the service time of the sandwich panel. Some manufacturers of sandwich panels often do tricks on the substrate and sandwich panel coating or coating. They reduce the thickness of the substrate, but increase the thickness of the peritoneum to reduce the production cost of sandwich panels, which greatly reduces the service life of color steel plates.
2.观察夹芯板的外漏边缘
2. Observe the leakage edge of the sandwich panel
拿到一块彩钢夹芯板，先观察外露板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。
Get a color steel sandwich board, and first observe whether the exposed board, such as the section, is fine and dense, gray, dark and impurities. If the section is fine crystalline, the quality is superior.
3.查看夹芯板的质量合格证明
3. Check the quality certificate of sandwich panel
是否有相关部门的检验标准。如果有可能的话尽量去玻镁夹芯板厂家实地考察。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 go to the glass magnesium sandwich panel manufacturer for field investigation. Look at the environment of the enterprise and whether it is formal. Ask about the reputation of this enterprise in the market.
4.听声音
4. Listen to the sound
用手指或用硬物敲击玻镁夹芯板，彩钢夹芯板的材质如果较差，则发出来的声音是闷的，金属声音不明显，材质较好的玻镁夹芯板金属声音是比较响亮、清脆的。
Knock the glass magnesium sandwich panel with fingers or hard objects. If the material of color steel sandwich panel is poor, the sound is dull and the metal sound is not obvious. The metal sound of glass magnesium sandwich panel with better material is relatively loud and crisp.
5.看价格
5. Look at the price
任何东西，都是一分钱一分货。我们在比较彩钢夹芯板质量的时候，价格是一方面，但是也不要太注重价格。如果一种夹芯板的价格别其他的低很多，那么我们就要有所注意了
Everything is worth every penny. When we compare the quality of color steel sandwich panel, the price is on the one hand, but don't pay too much attention to the price. If the price of one kind of sandwich panel is much lower than that of others, we should pay attention to it
