How to install the veneer of the ceiling?

1. Determine the height and draw a horizontal line on the wall with Mo Dou. 2. Fix the derrick at the top with iron expansion bolts, and fix the light steel keel below the derrick to keep it horizontal (if the grid span is less than 3m, the derrick is not needed). 3. Nail the aluminum corner line along the horizontal line with cement nails. 4. Put the aluminum grid on the ground and assemble it completely. 5. Place the assembled grid ceiling on the aluminum angle iron. The middle position is directly tied to the light steel keel with thin iron wire. 6. I suggest you find an installer in the store selling smallpox to install it, because they are professionally installed and relatively flat. If you need to cut off some window grilles when you put the lamp on it, they also have professional tools.
