Does the light steel keel gypsum board partition wall need to have a transverse keel in addition to the longitudinal keel? Can give the best set! Thank you first, big brothers and sisters, uncles and aunts. Transverse keel is necessary, especially at the joint of gypsum board, which should be glued to the bracket, otherwise the top surface will stay without strength for a long time. They are all placed at a spacing of 60cm, that is, a gypsum board is 2.4 meters long or 3 meters long.
