you can directly hang the ceiling with gypsum board, increase the gypsum lines of specifications and install a larger chandelier, which is effective, simple and saves money and trouble. You can also use normal light steel keel gypsum board! Gypsum lines are used for the corners of the roof and wall. Try to choose a larger one. Pay attention to the suspenders for installing chandeliers before the ceiling. The chandeliers are generally heavier, and the stress points must be above the floor, not above the ceiling. If you want to be more complicated, put a little round line around the chandelier on the ceiling. This is simple and neat, but it does not change and the cost is low. In fact, if the floor is flat, it is best to install lines and chandeliers directly without hanging the top!
