The color steel plate of Ji'nan movable house is made of coloured coated steel sheet, phenolic foam, self extinguishing polystyrene, polyurethane, glass wool and rock wool as core material, and super light building plate made of heat curing glue in continuous molding machine. It has the following characteristics:

1、规格多样化：如企业型、H型、C型、瓦楞型等，且色泽鲜艳，无须表面装饰。

1. Specification diversification: such as enterprise type, H type, C type, corrugated type, etc., and bright color, no surface decoration.

2、安装灵活方便：彩钢复合板不仅大量减少建设物的基础工程和结构工程费用，且能多次拆装，施工安装灵活方便，综合效益十分显著。

2. Flexible and convenient installation: the color steel composite plate not only greatly reduces the cost of foundation engineering and structural engineering of the building, but also can be disassembled for many times. The construction and installation are flexible and convenient, and the comprehensive benefits are very significant.

3、防火性好：彩钢板芯材为B1级难燃材料，其氧指数≥26，燃烧时不会熔融，且无黑烟，无高温分解滴落物。

3. Good fire resistance: the core material of color steel plate is Class B1 flame-retardant material, its oxygen index is more than or equal to 26, it will not melt during combustion, and there is no black smoke and high-temperature decomposition drop.

4、使用温度范围广：彩钢板芯材使用温度在-70℃～+120℃，在低温甚超低温环境中使用时收缩小，不脆化，是深冷工程理想的绝热材料。

4. Wide range of application temperature: the use temperature of color steel plate core material is - 70 ℃ ~ + 120 ℃. When it is used in low or even ultra-low temperature environment, it has small shrinkage and no embrittlement. It is an ideal insulation material for cryogenic engineering.

5、导热系数低，隔热保温性能。

5. Low thermal conductivity and good heat insulation performance.

6、无味：彩钢板芯材不用氟利昂发泡剂，燃烧时无味，溢出的气体对人体与环境均无害，符合要求，是一种新型绿色建材。

6. Non toxic and tasteless: the color steel plate core material does not use Freon foaming agent. It is non-toxic and tasteless when burning. The spilled gas is harmless to human body and environment, which meets the requirements of environmental protection. It is a new type of green building materials.

7、防水防湿：彩钢板芯材属于有机高分子发泡材料，其结构属闭孔型，具有良好的抗吸水性和抗水蒸气渗透性。

7. Waterproof and moisture proof: the core material of color steel plate belongs to organic polymer foaming material, its structure is closed cell type, with good water absorption resistance and water vapor permeability resistance.

8、自重轻，保温隔热，施工速度快，色泽鲜艳的特点，是一种集承重、保温、防水、装修于一体的新型围护结构材料。

8. With the characteristics of light weight, heat insulation, fast construction speed and bright color, it is a new type of envelope material integrating load-bearing, heat insulation, waterproof and decoration.
