Anonymous users2024-01-23The keel of the gypsum board ceiling is best made of light steel keel, which has high flatness and will not be deformed. If the area is small, then use fir squares. This is sold in general building materials stores, so just ask about it.

Anonymous users2024-01-22The surface of the light steel keel has been hot-dip galvanized, which does not rust and deform for a long time, and is a very good fireproof non-combustible material.
The traditional wooden keel is too much moisture, loves to deform, and is not fireproof, so in general, no one in large public places is suspended with wooden keel. In the past, because the amount of construction was relatively small, the carpentry used woodwork, but now with the improvement of living standards, the use of light steel keel is a general trend, and light steel keel is used in foreign countries.
Gypsum board should choose a relatively long fire-resistant time, such as Saint-Gobain refractory gypsum board, in the event of a fire, in a certain period of time to keep the structure intact, so as to block the spread of flames.
In addition to the fact that the formula of fireproof gypsum board is different from that of ordinary paper gypsum board, glass fiber is also added to increase its strength, which can effectively enhance the integrity of the board when exposed to fire. Ensure that it has a certain strength when exposed to fire and prolong the fire resistance time. Gain precious time to escape and fight fires.
The reduction of keel spacing can also greatly improve the strength and stability of the partition wall, which is helpful for resisting fire.

The building materials market has supporting products to choose from.
This question is a personal effort, so many questions at once! >>>More
The ceiling keel is used to withstand the falling force of gypsum board, disperse the force, and level the stability. >>>More
The curved shape of the gypsum board ceiling is difficult to make with keel, so it can only be contoured with woodworking board according to the curve shape, and then matched with wood keel or light steel keel. If the arc of the curve is not too large, it is also possible to use a wooden keel, but it is more troublesome and not cost-effective.
Are you asking whether a light steel keel ceiling or a wooden keel ceiling is better? Personally, I think that it is better to improve the home or the wooden keel, and the light steel keel that is mandatory in public places.
