If the spacing of the auxiliary keel is 300mm, then your screw spacing is slightly larger, 300mm, no problem.

Anonymous users2024-01-23There is no unified rule, depending on how long you make a wall, generally 30cm is a point, and you can add or subtract on this basis according to the length of the wall.
Self-tapping screws are treated with anti-rust paint, and nail caps are used conventionally. If you spray anti-rust paint by hand, it will be better than the point.
After a long time, there will be problems, because gypsum board is quite heavy, nails alone are far from enough, some gypsum board ceilings also have to be painted with white latex, and nails alone are the easiest to crack, but generally can't fall down, hehe.
Of course, there is, the distance between the ceiling nails, the self-tapping nail is not less than the cutting edge of gypsum board, and the distance from the wedge edge is not less than 1CM >>>More
Gypsum board ceiling, according to its modeling process and materials, etc., and the price is not the same, generally from 80---140 yuan square meters. The impression of the back street understands that the ordinary ceiling is about 80, and if the light steel keel is used and the modeling is added, the price is naturally higher.
It is best to do anti-rust treatment, otherwise rust will appear after the batch of putty is soaked in water, and the white will turn yellow to expose traces.
