What is the thickness standard for light steel keel

The thickness of the main bone is 1.2mm, 38 main bones are 1.0mm, 50 pairs of bones are 0.5mm, and 60 pairs of bones are 0.6mm vertically and along the ground.
Light steel keel is a new type of building material that has the advantages of light weight, high strength, adaptability to waterproof, shockproof, dustproof, and constant temperature. The difference between light steel keel and painted keel is that general light steel keel does not require surface treatment, and the surface of painted keel has been painted, generally divided into black and white. Light steel keel can be used for ceiling keel and partition keel, and can be divided into V-shaped, C-shaped, T-shaped, and L-shaped keels according to the cross-sectional form.
The ceiling keel plays a very important role in ceiling decoration. It is the skeleton of the ceiling, playing a role in shaping and load-bearing. It is used to fix the ceiling or objects. The ceiling keel is also the ceiling, especially the shaped ceiling, which is made of light steel keel as the frame and then covered with gypsum board.
The maximum distance between the main keel and the main keel cannot exceed 1.2m. If this distance is exceeded, reinforcement measures should be taken. The distance between the auxiliary keels is 30cm, and the thickness of the gypsum board is 9.5mm. The thickness of the gypsum board is 12mm, and the distance between the auxiliary keels can be enlarged to 40cm.
