The derusting operation of the fast assembly container is also very important. The fast assembly container should be derusted and painted once every 3-5 years, so as to maintain the overall structure of the fast assembly container for a longer time and make the container house more beautiful. The fast assembly container uses a metal frame. When the user installs electric lighting equipment, the wires cannot be directly tied to the container house. Line pipes or grooves should be laid to prevent electric shock. After the installation of the container house is completed, the user shall not modify the internal structure of the container house without authorization, install bolt components, or add partition walls.
