Anonymous users2024-01-23One you said is an aluminum gusset ceiling and the other is a ceiling that is afraid of V, all of which are similar, and the price is different.
A square investment in a light steel keel gypsum board ceiling is about 30 40 yuan. >>>More
Either all are calculated according to the projected area, or all are calculated according to the area, and there is no need to calculate them separately. Both calculation methods are OK, but they are not the same in terms of unit price.
Judging from the situation you said above, you don't seem to know about the project, the light steel keel is the material that plays a tensile role inside, and the gypsum board is sealed on the light steel keel, why there are two ceilings. The ceiling is only divided into two kinds, one is the bright keel ceiling and the other is the dark keel ceiling, the bright keel is sealed with silicon cover plate (a piece is connected to the kind), and the dark keel is completely closed with gypsum board. The wooden keel is the same thing as the light steel keel, that is, the base layer is made of different materials. >>>More
Gypsum board is cheap, about 26 yuan a piece, and the keel is relatively expensive. You can use wooden keel ceilings!It's cheaper. Generally, the wooden keel is 22 yuan, 6 pieces, and 3 meters should be 3 * 3 best, and the rules are pointed.
The spacing of the main keel is generally between 80 120 cm, depending on how thick the gypsum board is used, if the gypsum board is thick, or it is a double-layer gypsum board, the spacing of the main keel should be small, otherwise it can be appropriately enlarged, but can not exceed meters; The spacing of the suspension bar is also the same, and the distance between the suspension bar and the suspension bar can be determined according to the size of the main keel, but the same can not exceed the meter; 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
