The fast assembled container house is also called "quick assembling container". The "flat-pack container house" transferred from the shipping container house.
The big difference between the fast assembled container and the flat pack container is that the frame connection form is different.
The fast assembled container house connects the column and the top and bottom beams by fastening screws, while the flat pack container house connects the column and the top and bottom beams by welding.
Therefore, the time of assembling flat pack container house is much faster than that of fast assembled container house. Of course, flat pack container house is slightly better in the aspects of firmness and waterproof.
