Whether the ceiling of the living room is made of wooden keel or light and rigid

The wooden keel is more convenient to shape, but it is not fireproof, the light steel keel is not good for modeling, but the fire performance is good, the best is to use the wooden keel where there is a modeling, and the others are good with light steel keel, and the current calcium silicate board, gypsum board, and woodworking board are 1200x2400mm 1220x2440mm This is basically the basic size of the partition board.

Hello, this one is nothing; It depends on what your ceiling looks like; If it is a complex shape, it must be shaped with a wooden keel; If it is simple, a light steel keel can also be used; The light steel keel is firm, anti-corrosion and anti-insect (some poor wooden keels have insect eggs in them); Decide for yourself!

Wooden keel ceiling:

Keel brush fireproof coating twice, keel tenon, fixed with iron nails, each joint with two iron nails fixed, made into a 300 * 300 or 400 * 400 frame, installed on the top, (it is forbidden to use a rigid row of nails, nails to fix the frame), adjust the height, straight, after acceptance of the gypsum board, the use of self-tapping fixation, self-tapping density: 20cm, the edge part should be denser.

The wooden keel is combined with the light rigid keel:

This is not recommended, I personally feel that it is not as strong as a full wooden keel or a completely light rigid keel. And it is more troublesome to adjust the straightness during construction.

Completely use a light rigid keel:

Expansion screws, sockets, etc., are used to make the installation more robust. The light and rigid keel has the characteristics of fire resistance, not easy to deform, and is a method commonly used by most decoration companies. Whether it is a large-area ceiling or a partial ceiling, this method can be used for construction.

Now most of them are made of light steel keel, which is heavy-bearing, not easy to deform, and flame retardant.

You can put it, if you want to save money, if you hang it locally, the wooden dragon will be fine.
