There are three main categories of portable dwellings, mainly cement prefabricated homes, galvanized steel sheet prefabricated homes, and color coated steel coil prefabricated homes.

The prefabricated house is made of light steel as the skeleton, the walls are made of sandwich panels, and the components are connected by bolts. It is a relatively environmentally friendly and economical prefabricated house.

The main uses of prefabricated houses are: first, construction sites, such as project office areas, worker dormitories, etc.; second, houses for field operations, such as field surveys, etc.; third, emergency houses, such as temporary command centers for military operations, earthquake relief, etc.

Specific classification of portable dwellings:

1. Cement portable dwellings: This type of mobile houses is mainly used on construction sites, as offices and dormitories for migrant workers, and can also be used in flat-roof additions and warehouses. The load-bearing system of the cement mobile house is mainly a steel structure, and the walls are made of double-layer steel mesh, insulation materials and cement prefabricated composite panels. Transportation and installation are quick and convenient, and the door locks and windows are fully equipped.

2. Galvanized Steel Coil portable dwellings: The hardness of galvanized sheet is lower, while its toughness and tensile ability are significantly better. From a visual point of view, galvanized sheets are more stable, natural and more in line with the "iron texture".

3. Colored steel house portable dwellings: This type of mobile house is a light steel structure, and the walls are a combination of colored steel plates and coated polyethylene foam sandwich composite panels. The service life is 10 to 20 years, the thermal insulation effect is good, and the interior can be decorated with ceilings.
