The thickness of gypsum board is usually 9.5mm, 12mm, 15mm, and some are below 9.5mm, but they are generally non-standard; the length is 2400mm, 3000mm, and the width is mostly 1200mm.

Generally, the gypsum board on both sides of the light steel keel is well divided into two types: the thickness of the putty is 10 cm and the thickness of 11 cm. 9.90cm, the wall thickness is greater than 10cm after painting. The thickness of type 100 and 150 light steel keel partition wall and so on.
