Integrated Container House Roof

The key points for purchasing, installation, and craftsmanship of integrated container house roofs are as follows:

Purchase Stage

• Structural Type: On the market, there are commonly welded integral containers and bolt-connected assembled containers. Welded container bodies are formed by integral welding in the factory, with a direct force path and strong resistance to deformation, suitable for frequent lifting and moving. Assembled containers use standard plates connected by bolts, with multiple connection nodes in the force path. The tightness of each node directly affects the overall stability. When purchasing, check the steel wall thickness of the columns and bottom beams, with common specifications ranging from 1.5 mm to 3 mm. The thicker the wall thickness, the greater the load-bearing redundancy, but the self-weight also increases accordingly.
• Coating Process: The quality of the coating directly affects the rusting speed of the container body, especially in areas with large temperature differences between day and night and significant humidity changes. Hot-dip galvanizing treatment has a longer anti-corrosion lifespan than cold-dip galvanizing and should be preferred for container roofs.
• Waterproof Process: Traditional integrated houses with spliced roof panels are prone to leakage at the spliced seams after long-term use. Full-weld sealing process eliminates leakage risks from the source by fully welding the seams of the roof panels. Combined with a waterproof and thermal insulation composite layer, it can simultaneously achieve multiple effects such as waterproofing, fire resistance, and thermal insulation, making the overall structure of the house more stable and extending its service life.

Installation Stage

• Ground Treatment: The bottom beams of container houses are usually I-beams or channel steels, with limited contact area with the ground. If placed directly on soft soil, local pressure can cause uneven settlement of the container body, leading to deformation of doors and windows and cracks in the walls. For long-term fixed use, a concrete strip foundation needs to be poured, with a recommended width of 30 cm to 50 cm and a depth determined according to the local frost depth. The top surface of the foundation should be kept level, with a height difference not exceeding 5 mm. For short-term use scenarios, pre-fabricated concrete pads or steel pads can be used, with a pad spacing not exceeding 2 m. Additionally, a crushed stone leveling layer should be laid under each pad to ensure that the force points are on the same horizontal plane.
