What should we do if the ceiling is not flat after the ceiling of the mineral fiber board is completed?

Precautions:

1) The hanging ribs must be straightened, and anti-rust treatment is required. The distance between the hanging points should be controlled within 1200mm, 900mm is recommended, and the installation is firm and no looseness;

2) The laying of the ceiling is accurate, and the arching needs to be calculated to determine the arching height and not less than 1/200 of the short span of the room;

3) Heavy-duty lamps and equipment are forbidden to be installed on the keel of the ceiling project due to the special hanging ribs.
