It is a common practice to use woodworking board for the shape of the light strip, and there is no hidden danger of bending, expansion and deformation, at least I have been engaged in decoration for decades, and I have not seen or heard of this situation. I hope my answer can help you.

The problem is not big, and the overall deformation of the woodworking board is relatively small.
About one meter, but it also depends on the size of the specific area of the top.
When buying a light strip, it should be with mounting nails, and it is recommended to choose AIA ceilings to buy to prevent being deceived. >>>More
The cracking of the gap position is caused by the improper use of materials, and the cracking is caused by thermal expansion and contraction or slight vibration, and the gap between the gypsum board (board) is more suitable with a tough caulk, which has toughness to reduce the cracking phenomenon, and reduces the use of worry-free toughness caulk for caulking treatment (TB).
The final aesthetic effect and maintenance convenience of gypsum board ceiling and aluminum gusset are different. >>>More
The more standardized approach should be to use the expansion screw rod to make the suspension bar, and then the light steel keel main bone, auxiliary bone, and surface gypsum board. There will be no problem with such a construction process.
