Thickness and specifications of light steel keel partition walls

1. The commonly used specifications for light steel keel in partition walls are generally 75mm and 100mm. This specification determines the thickness of the partition wall, and the length is generally 3m and 4m. The specifications and thicknesses of gypsum board are usually 9.5mm, 12mm, and 15mm. There are also some thicknesses below 9.5mm, but they are generally non-standard, with lengths of 2400mm, 3000mm, and widths mostly of 1200mm.
2. Generally, there are two types of gypsum board partitions on both sides of the light steel keel: one with a thickness of 10cm and the other with a thickness of 11cm. The general keel thickness is 7.5cm, and the double-sided double-layer sealing plate (1.20cm) of the 75 type light steel keel partition wall has a thickness of 9.90cm. After painting, the wall thickness should be greater than 10cm. The thickness of the wall of the 100 type and 150 type light steel keel partition is calculated accordingly.
3. The construction of light steel keel is not static. Sometimes during construction, it is necessary to add cross bracing and reinforced keels, and the spacing between vertical keels should be determined based on the width of the gypsum board. Usually, one piece is placed on the edge and one piece is placed in the middle of the gypsum board. The spacing should not exceed 600mm. When using materials such as tiles for wall decoration, the weight will increase. At this point, the distance between the keels cannot exceed 420mm. If the height of the partition wall needs to be increased, the distance between the keels should also be correspondingly reduced.
