彩涂钢板的基板分为：冷轧基板，热镀锌基板和电镀锌基板。涂层种类可分为聚脂、硅改性聚脂，偏聚二氟乙烯和塑料溶胶。

The substrates of color coated steel plates are divided into cold-rolled substrates, hot-dip galvanized substrates, and electroplated galvanized substrates. The types of coatings can be divided into polyester, silicon modified polyester, polyvinylidene fluoride, and plastic sol.

彩涂钢板的表面状态可分为：涂层板、压花板和印花板，彩涂钢板广泛用于建筑家电和交通运输等行业，对于建筑业主要用于钢结构厂房、机场、库房和冷冻等工业及商业建筑的屋顶墙面和门等；民用建筑采用复合型彩钢板的较多。

The surface condition of color coated steel plates can be divided into coated plates, embossed plates, and printed plates. Color coated steel plates are widely used in industries such as construction appliances and transportation. For the construction industry, they are mainly used for roof walls and doors of industrial and commercial buildings such as steel structure factories, airports, warehouses, and refrigeration; There are many civil buildings that use composite color steel plates.

彩钢板的特性：重量轻，只有10-14千克/，相当于砖墙的1/30 ；隔热保温芯材导热系数λ<=0.041w/mk。 耐腐蚀、耐老化、使用寿命长；消音、隔热方面性能尤其突出 ；安装成本低 ，方便快捷，无后续维护费用，施工周期可缩短40%以上；色泽鲜艳，无须表面装饰，彩色镀锌钢板防腐层保持期在10-15 年。

The characteristics of color steel plate: lightweight, only 10-14 kilograms per square meter, equivalent to 1/30 of a brick wall; Thermal conductivity of insulation core materials λ<= 0.041w/mk. Corrosion resistance, aging resistance, and long service life; The performance in terms of noise reduction and thermal insulation is particularly outstanding; Low installation cost, convenient and fast, no subsequent maintenance costs, and the construction cycle can be shortened by more than 40%; The color is bright and does not require surface decoration. The anti-corrosion coating of colored galvanized steel plate has a retention period of 10-15 years.

彩钢板的内部材料分类主要有： 聚氨酯夹芯板、聚苯乙烯（EPS）夹芯（泡沫）板、岩棉夹芯板、玻璃丝绵夹芯板等。其中，防火性能好的是岩棉夹芯或玻璃丝绵夹芯，属于防火性能A级建筑材料，常见的有抗震活动板房以及大跨度厂房就使用的这类产品。

The internal materials of color steel plate mainly include: polyurethane sandwich board, polystyrene (EPS) sandwich (foam) board, rock wool sandwich board, glass wool sandwich board, etc. Among them, rock wool sandwich or glass wool sandwich have good fire resistance performance, which belong to A-level building materials with fire resistance performance. Common products used include earthquake resistant activity board houses and large-span factory buildings.

目前市场上常见的主要是聚苯乙烯和聚氨酯夹芯的彩板，燃点极低、阻燃性差，聚苯乙烯（泡沫）的燃点是346℃，仅比木材燃点高一点，聚氨酯燃点仅在130℃左右，跟普通纸张类似，遇到明火或电气线路短路会立即燃烧，这类彩钢板在燃烧时会产生大量浓烟，其成分主要是一氧化碳和氰化氢等有毒气体。

At present, the common ones in the market are polystyrene and polyurethane sandwich color plates, which have very low ignition point and poor flame retardancy. The ignition point of polystyrene (foam) is 346 ℃, which is only a little higher than that of wood. The ignition point of polyurethane is only about 130 ℃. Similar to ordinary paper, it will burn immediately in case of open fire or short circuit of electrical circuit. Such color plates will produce a lot of thick smoke when burning, Its main components are toxic gases such as carbon monoxide and hydrogen cyanide.
