Dear for you to find out.
The spacing of the secondary keel (50 keels) is 30 cm when gypsum board is generally used, and if the thickness of the gypsum board is 12mm, the spacing of the secondary keel can be enlarged to 40 cm. But in our case, we basically use 30 cm spacing. >>>More
Home decoration with wooden keel is good construction, but there is also a little bad easy to deform, now home decoration is basically using light steel keel, the price is about the same and tooling gypsum board ceiling with light steel keel, his area is large, wooden keel can not withstand such a large weight here,
The difference between light steel keel ceiling and wooden keel ceiling is that one is made of light steel keel as the skeleton, and the other is made of wooden keel as the skeleton, and the surface is sealed with gypsum board. The ceiling made of light steel keel is better than the ceiling made of wooden keel; The light steel keel will not be deformed, while the wooden keel will be deformed, so if the wooden keel is used for the ceiling, the possibility of cracks at the joints of the gypsum board is higher than that of the light steel keel. Of course, the cost price of light steel keel will be slightly higher than that of wooden keel.
