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、規格多樣化：如企業型、H型、C型、瓦楞型等，且色澤鮮艷，無須表面裝飾。

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

2、安裝靈活方便：彩鋼復合板不僅大量減少建設物的基礎工程和結構工程費用，且能多次拆裝，施工安裝靈活方便，綜合效益十分顯著。

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：彩鋼板芯材為B1級難燃材料，其氧指數≥26，燃燒時不會熔融，且無黑煙，無高溫分解滴落物。

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、使用溫度范圍廣：彩鋼板芯材使用溫度在-70℃～+120℃，在低溫甚超低溫環境中使用時收縮小，不脆化，是深冷工程理想的絕熱材料。

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、導熱系數低，隔熱保溫性能。

5. Low thermal conductivity and good heat insulation performance.

6、無味：彩鋼板芯材不用氟利昂發泡劑，燃燒時無味，溢出的氣體對人體與環境均無害，符合要求，是一種新型綠色建材。

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、防水防濕：彩鋼板芯材屬于有機高分子發泡材料，其結構屬閉孔型，具有良好的抗吸水性和抗水蒸氣滲透性。

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、自重輕，保溫隔熱，施工速度快，色澤鮮艷的特點，是一種集承重、保溫、防水、裝修于一體的新型圍護結構材料。

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.
