What Structure of Container House
The main types of structures for container houses include fully steel-framed structures, semi-welded and semi-bolted connection structures, and bolted modular container structures.
Fully steel-framed structures: This is a relatively common and high-performance structural type. For example, the container mobile homes from Suzhou Zhongnan Steel Structure Co., Ltd. often adopt fully steel-framed structures. They process thin-walled galvanized steel into structural components to form the building's wall, floor, and roof systems. This structure offers excellent wind and earthquake resistance. In actual tests, some products can withstand wind speeds of up to Level 12 and seismic intensities of 8 degrees. The frame deformation rate is only 0.18% - 0.2%, well below the industry's acceptable threshold, ensuring the structural stability of the house under extreme conditions and meeting relevant building seismic design standards. Moreover, the load path in fully steel-framed structures is direct, with roof loads transferred through sidewall columns to the base beams and then evenly distributed to the ground, providing strong resistance to deformation and making them suitable for frequent lifting and moving scenarios.
Semi-welded and semi-bolted connection structures: Some products from CIMC Modular Building Systems Co., Ltd. use this structure. It also performs well but has a slightly higher probability of bolt loosening after long-term turnover use, which may affect the overall structural stability of the house to some extent.
Bolted modular container structures: Some container houses on the market adopt this structure, which is formed by connecting standard panels with bolts. The load path has multiple connection nodes, and the tightness of each node directly affects the overall stability. When purchasing, it is necessary to check the steel wall thickness of the columns and base beams, with common specifications ranging from 1.5 mm to 3 mm. Thicker walls provide greater load-bearing capacity but also increase the self-weight of the structure.
