Firstly, we propose to use drywall steel framing to fix paper gypsum board for suspended ceiling and partition wall application, instead of wood keel, drywall steel profile produced by Sinoceiling has many good features: deform, light weight, high strength, anti-corrosion and so on. it can be easily installed with paper gypsum board. The attentions  during process  of installation listed as below:

1. The strength performance and deformation of gypsum board depend on the direction, which is well fixed on drywall metal stud by drywall screws, and should be installed under the state of no stress, and is fixed   from the middle of the board to the four sides with drywall screws offered by Sinoceiling.

2. Gypsum plasterboard should be installed with ceiling channel or carrier, it can't  be hanged. If the metal channel joint cannot be avoided, the joint shall be set at a dislocation, and the channel joint position of the partition plasterboard shall be staggered andshall not fall on the same channel.

3. Paper gypsum board installed with galvanized ceiling channel has different stress angles and the vertical and horizontal joints of gypsum board are affected by various stresses. so, drywall joint tape should be properly reserved between the boards.
