20ft Prefab Office is equipped with an internal power system and can be used as a container alone, or it can be connected with other containers to form a new building and used as an office.
Installation Steps
This prefab office installation follows four quick steps:
- Lay the completed base on-site, ensuring a solid foundation.
- Connect the four corner columns for structural support.
- Position and secure the roof frame on top.
- Complete the build with walls, doors, and windows—ready to use. This efficient setup showcases the simplicity and speed of prefab office construction, ideal for fast deployment in any location.
Prefab Office installation and loading steps
- Packing preparation: Each prefab office prefabricated room has completed the installation of the floor and roof before leaving the factory to ensure the overall structure is stable.
- Hoisting and stacking: Use hoisting equipment to stack the packaged prefab office modules firmly.
- Forklift loading: Use a forklift to push the packaged prefab office units into the 40-foot high cabinet container to ensure that the box is evenly distributed to avoid slippage or deformation during transportation.
- Sealing: When the 40HQ container is filled with 8 sets of prefab office, it is sealed, reinforced, and affixed with shipping labels and shipped to all parts of the world.
