Basically, it is not needed because it has no practical meaning.
The light steel is slightly stronger, not easy to deform, and the wooden keel can also be, but its expansion and contraction rate is greater than that of the light steel keel, and the gypsum board joints are easy to crack after a long time.
Now the decoration is no longer allowed to use wooden keel ceilings, and the specification is to use light steel keels to ensure that the roof is not cracked and deformed. Only the place where the shape is partially used can be a large core board. Gypsum board ten or twelve thick, anti-crack can be sealed in two layers.
