The steps to install ceiling T-shaped grille are as follows:
Determine the height: Use a plumb line to draw a high horizontal line on the wall.
Fix the hanging rod: Use expansion bolts to fix the hanging rod on the top, fix the light steel keel under the hanging rod and keep it horizontal (if the grille span does not exceed 3 meters, the hanging rod can be omitted).
Install the aluminum angle line: Use cement nails to nail the aluminum angle line along the horizontal line.
Assemble the grille: Put the aluminum grille on the ground and assemble it completely.
