Color steel plate is a new material composed of two-layer formed metal panel and polymer insulation inner core foamed and matured directly in the middle of the panel. Because of its light weight, heat insulation, high strength, bright color, flexible installation and short construction cycle, it is favored by the construction industry and is widely used in long-span plants, warehouses, office buildings, roof adding floors, shops and temporary buildings.

1.聽聲音辨別質量，用手指或用硬物敲擊彩鋼板，彩鋼板的材質如果較差，則發出來的聲音是悶的，金屬聲音不明顯，材質較好的彩鋼板金屬聲音是比較響亮、清脆的。

1. Listen to the sound and identify the quality. Knock the color steel plate with your fingers or hard objects. If the material of the color steel plate is poor, the sound is dull and the metal sound is not obvious. The metal sound of the color steel plate with better material is loud and crisp.

2.查看彩鋼板的質量合格證明，是否有相關部門的檢驗標準。如果有可能的話盡量去彩鋼板的生產廠家實地考察?？纯雌髽I的環境怎么樣，是否正規。市場上打聽一下這個企業的口碑怎么樣。

2. Check the quality certificate of color steel plate and whether there are inspection standards of relevant departments. If possible, try to go to the manufacturer of color steel plate 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.

3.觀察彩鋼板的外漏邊緣，拿到一塊彩鋼板，我先觀察彩鋼板外露鋼材如斷面等是否結晶細密，是否發灰、發暗和雜質。若切面是結晶細密型的則是質量比較優越的。

3. Observe the leakage edge of the color steel plate and get a color steel plate. I first observe whether the exposed steel of the color steel plate, such as section, is fine and dense, gray, dark and impurities. If the section is fine crystalline, the quality is superior.

4.觀察基板厚度和覆膜的厚度，彩鋼板是有基板和彩色的腹膜或者鍍層構成的。我們首先得考慮基板和腹膜鍍層的厚度，比較好的彩鋼板基板是0.02~0.05mm，覆膜或者涂層厚度往往只有0.15mm以下。因為從影響彩鋼板的使用時間來看，基板的厚度是很重要的。而有些生產彩鋼板的廠家往往在基板及彩鋼板涂層或覆膜上做手腳，他們降低基板的厚度，但是增加腹膜的厚度來降低彩鋼板的生產成本彩鋼板，彩鋼板廠家分享彩鋼板質量這就大大降低了彩鋼板的使用壽命了。

4. Observe the substrate thickness and coating thickness. The color steel plate is composed of substrate and color peritoneum or coating. We must first consider the thickness of substrate and peritoneal coating. A better color steel 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 color steel plate. However, some manufacturers of color steel plate often do tricks on the substrate and color steel plate coating or coating. They reduce the thickness of the substrate, but increase the thickness of the peritoneum to reduce the production cost of color steel plate. Color steel plate manufacturers share the quality of color steel plate, which greatly reduces the service life of color steel plate.
