I am doing light steel keel ceiling partition wall has no market under construction, solve

1. Can all such cheap materials be used for engineering? What brand is the keel? What are the models and specifications? Can it meet the scope of safe use of national standards? Taishan gypsum board don't whole cottage. What West Lake, what King Taishan, fool us.

1. The state has not issued specific standards for the time being, but the industry knows the standards. >>>More

We estimate it based on the total length of the light steel keel partition wall. For example, the number of roots of the vertical keel is calculated by multiplying the total length of the partition wall; The total length of the heaven and earth keel is calculated by multiplying the coefficient of the total length of the partition wall; The number of piercing keels is limited by the height of the partition wall, if two are placed at a height of 3 meters, it is calculated as (not exceeding) twice the total length of the partition wall. >>>More

The ceiling keel has the main keel, the side keel and the auxiliary keel, the main keel has 50, 60 and cassette keel, the auxiliary keel has 50 and 60 keels, the partition wall keel has a vertical keel, the heaven and earth keel and the piercing keel, the vertical and the heaven and earth have 70, 100, 150, 200 specifications,

According to the normal process, the ceiling should be made first and then the partition wall. If you have no choice but to sit on the partition wall first, you can only do the ceiling elevation, the reason is that the top of the light steel keel partition wall needs to be fixed on the ceiling, how to fix it if you are 20 higher? That's it.
