Color steel plate is not suitable for the roof of long-term residential houses because:

1.彩钢板保温、隔热、隔音性能差：从造价设计来看，一般彩钢板活动房的保温、隔声性能相对较弱。如果想提高隔热隔音效果，就需要加厚隔墙和隔墙。费用会增加。

1. Poor thermal insulation, heat insulation and sound insulation performance of color steel plate: from the perspective of cost design, the thermal insulation and sound insulation performance of general color steel plate movable houses is relatively weak. If you want to improve the effect of heat and sound insulation, you need to thicken the partition wall and partition wall. The cost will increase.

2.彩钢板抗风、抗雪、抗压能力弱：一般无骨彩钢房屋抗压能力较弱。一般只建一层，骨架活动房屋采用C型钢和工字钢，可大大提高其抗压能力。但是，通常不建议在长久性建筑施工中使用。

2. The wind resistance, snow resistance and compressive capacity of color steel plate are weak: generally, the compressive capacity of boneless color steel houses is weak. Generally, only one floor is built, and the skeleton movable house adopts C-section steel and I-beam, which can greatly improve its compressive capacity. However, it is generally not recommended to use it in long-term building construction.

彩钢板通常适用于工业民用建筑、仓库、特殊建筑、大跨度钢结构房屋的屋面、墙面及内外墙装饰。具有重量轻、强度高、色彩丰富、施工方便快捷、抗震、防火、防雨、使用寿命长、免维护等特点。它已经得到了广泛的推广和应用。

Color steel plate is generally applicable to the roof, wall and internal and external wall decoration of industrial and civil buildings, warehouses, special buildings and long-span steel structure houses. It has the characteristics of light weight, high strength, rich colors, convenient and fast construction, earthquake resistance, fire prevention, rain proof, long service life, maintenance free and so on. It has been widely popularized and applied.

彩钢板的优点：

Advantages of color steel plate:

1.重量轻：10-14kg/m2，相当于砖墙的1/30。

1. Light weight: 10-14kg / m2, equivalent to 1 / 30 of brick wall.

2.高强度：可作为吊顶围护板承受荷载、弯曲和压缩;一般房屋不使用梁和柱。

2. High strength: it can be used as ceiling enclosure board to bear load, bending and compression; General houses do not use beams and columns.

3.色泽鲜艳：无需表面装饰，彩色镀锌钢板防腐层保存期为10-15年。

3. Bright color: no surface decoration is required, and the preservation period of the anti-corrosion coating of colored galvanized steel plate is 10-15 years.

4.安装灵活快捷：工期可缩短40%以上。

4. Flexible and fast installation: the construction period can be shortened by more than 40%.

彩钢板不适合长期作为房屋屋顶比较主要的一个原因就是它的隔热保温性能比较差，如果想增强次性能，就需要多花一大笔钱，这就不太值当了，因为本身人们选择彩钢板就是为了节省成本。

The main reason why people choose colorful steel plate as thermal insulation is that it is not worth a lot of money in the long term. If it is not suitable for the roof, the main reason is that it is not worth a lot of money.
