1. Look at the appearance

The color of integrated houses with activity board houses should be coordinated as a whole. High quality integrated houses with activity board houses have uniform color steel plates and a hard and smooth texture. In addition, it is necessary to carefully inspect the installation components of the integrated house of the prefabricated house before leaving the factory to ensure that they are qualified and the welding is firm.

2. Check the fire resistance performance

Before purchasing a prefabricated house, it is necessary to check the fire resistance performance and whether all the wires inside the house are concealed in the fire prevention management. Check whether the inner and outer layers of iron sheets of the color steel sandwich panel are damaged, and do not expose the insulation layer in the middle.

3. Check the fire resistance performance

There shall be no water leakage on the roof, doors, windows, walls, and floors of the integrated house in the prefabricated house. The roof panel and supporting components must have a reliable connection, otherwise if encountering severe weather conditions such as strong winds, the roof of the integrated house with movable panels is easily damaged.

4. Look at the light

The wall panels, doors, windows, and components of the prefabricated house must not have visible light gaps after assembly. If there is light leakage, it indicates that the thermal insulation performance of the prefabricated house is not very good, and any gaps will inevitably lead to air leakage.

5. Pay attention to details

Whether the doors and windows of the integrated house of the activity board house are flexible and the locks are firm. The guardrails of corridors and stairs should be smooth and free of burrs. The integrated house of activity board house should have flat and firm floor slabs, and there should be no shaking feeling when people walk on them. The connecting parts should have waterproof sealing measures.
