從彩鋼板的材料分析來看，彩鋼夾芯板已彩色涂層鋼板為面材，芯材主要有聚苯乙聚、氨酯、巖棉三種。
From the material analysis of color steel plate, the color steel sandwich plate has been color coated steel plate as the surface material, and the core materials mainly include polyphenylene glycol polymer, urethane and rock wool.
目前，大部分彩鋼板內保溫材料為聚苯乙烯和聚氨酯，他們具有重量輕、操作工藝簡單和低成本等優勢，但是其燃點低、阻燃性差。聚苯乙烯的燃點是345℃，而木材的燃點是250℃至300℃，僅比木材燃點高一點，而聚氨酯燃點僅在130℃左右。
At present, most of the internal insulation materials of color steel plate are polystyrene and polyurethane. They have the advantages of light weight, simple operation process and low cost, but they have low ignition point and poor flame retardancy. The ignition point of polystyrene is 345 ℃, while that of wood is 250 ℃ to 300 ℃, which is only a little higher than that of wood, while that of polyurethane is only about 130 ℃.
聚苯乙烯和聚氨酯在燃燒時會產生大量的濃煙，其成分主要是一氧化碳、氰化氫等，煙氣毒性較大。
Polystyrene and polyurethane will produce a large amount of thick smoke when burning. Its components are mainly carbon monoxide, hydrogen cyanide, etc., which is highly toxic.
彩鋼板火災具有蔓延速度快、煙火蔓延途徑多、容易形成立體火災、燃燒產物中含有毒氣體、撲救比較困難和容易造成建筑坍塌等特點。
Color steel plate fire has the characteristics of fast spread speed, many ways of fireworks spread, easy to form three-dimensional fire, toxic gas in combustion products, difficult fire fighting and easy to cause building collapse.
在彩鋼板不斷進步的時代，想要有效防火，使用的安全，就得選用防火性能好的彩鋼板，例如：精鋼覆膜瓦！
In the era of continuous progress of color steel plate, if you want to completely prevent fire and use safety, you have to choose color steel plate with good fire resistance, such as precision steel coated tile!
