1. High maintenance cost
Due to the external spray painting for a long time, it will peel off and affect the appearance. Therefore, maintenance should be done once every two years, that is, spray painting and plastic spraying. However, no maintenance will not affect the use.
2. Poor thermal insulation and sound insulation performance
Based on the cost of design, the general color steel activity room in the insulation and sound insulation performance is relatively weak, if you want to improve the heat insulation and
sound insulation effect, you need to thicken the partition and partition. The cost will increase.
3. The resistance to wind and snow is weak
The general boneless color steel house is relatively weak in terms of compressive capacity. Generally,
only one floor is built. C-shaped steel and I-beam steel are used in the movable room with skeleton, which can greatly improve the compressive capacity. However, it is generally not recommended for the construction of permanent buildings.
is easy to rust over time
Due to the steel late + spraying material, when the coating peels off, the internal steel plate is easy to rust, thus affecting the use.
