The main materials of container mobile homes are channel steel for frames and sandwich panels for walls and ceilings. The quality of these two materials directly affects the quality of container mobile homes.

The difference in channel steel is mainly reflected in the difference in the thickness of the channel steel. Although the living containers sold by some manufacturers have little surface difference, the thickness of the channel steel is different, and the tolerance of the residential containers produced is also different. Some residential containers can be stacked three layers and can withstand greater pressure, while some residential containers can only be stacked two layers and cannot withstand the pressure caused by three layers.
How to identify the quality of container mobile homes?
1. If the thickness of the channel steel is not enough, it will easily bend when subjected to pressure, and the residential container will be deformed, thus affecting the service life. This type of container mobile home cannot see changes in a short period of time, but over time it is prone to deformation, collapse and other problems, which may endanger the safety of people inside the container mobile home. Therefore, there are certain standards for the selection of channel steel for residential containers. You cannot use channel steel materials lower than the standard just to save costs, as this may easily cause problems.
2. For residential containers with white roofs and white boxes with iron roofs, the quality of the color steel sandwich panels directly affects the service life of the residential containers.
3. Currently, the color steel sandwich panels on the market are of mixed quality. Some are used for container mobile houses, and some are used for prefabricated houses. The thickness of the steel plates of the color steel sandwich panels used for different purposes varies greatly. If the color steel sandwich panels used in prefabricated houses are used on residential containers, the color steel sandwich panels may have a series of problems such as steel plates falling off and rusting after a few months, and the residential containers may be damaged.
4. Therefore, residential containers must use color steel sandwich panels specially designed for residential containers. Color steel sandwich panels that do not meet the standards cannot be used because of the need to reduce costs. This will easily affect the service life of the residential container.
