Plate fixation:

Use rust-proof self-tapping screws to fix the gypsum board, with a nail spacing of ≤ 200mm and a nail tail recessed 0.5-1mm into the board surface without breaking the paper surface.

The seams are staggered, and L-shaped whole boards are used at the corners to prevent cracking.

Sealing treatment:

Fill the joints with gypsum and hang a mesh cloth. Apply latex paint after scraping the putty.

Attention:

The acceptance of concealed works requires checking the firmness of the keel and fire and anti-corrosion treatment.

Avoid conflicts between hanging bars and lighting fixtures, and reserve inspection ports.

The above process integrates national standards and the latest industry technology and is suitable for the construction of light steel keel ceilings in most residential and commercial spaces.
