The prefabricated expansion container room process is to apply modular construction technology to the manufacturing process of expansion container rooms, standardize the modular design of building components, and manufacture them in factories, and finally assemble them on site.

The specific process steps are as follows:

1. Design the structure and size of the customized expansion container room, draw construction drawings and manufacturing process drawings.

2. Cut the steel into corresponding plates and profiles according to the size requirements.

3. Punch, bend, cut, drill and weld the iron plate to make standardized components and components.

4. Coat or embed components that require special materials such as insulation, fireproofing and corrosion resistance.

5. Clean, dry, rust-proof and film the manufactured module components.

6. Install building doors and windows, electrical equipment, pipe fittings and other related accessories.

7. During on-site construction, modular assembly and splicing are carried out according to the design drawings and assembly process sequence.

8. After passing the final inspection, the expansion container room is used and delivered.
