Light steel keel is a kind of building material which is widely used in the construction industry. It is made of thin steel plates and has a variety of shapes and sizes. In order to ensure the stability and safety of the structure, it is necessary to use screws to fix the light steel keel. So what size of screws should be used for light steel keel?

The size of screws used for light steel keel depends on the thickness of the steel plate. Generally, the thickness of the steel plate is 0.5-1.2mm, and the size of the screws used is M3.5-M5.5. If the thickness of the steel plate is greater than 1.2mm, the size of the screws should be increased accordingly.

In addition, when installing the screws, it is necessary to pay attention to the distance between the screws. Generally, the distance between the screws should be greater than or equal to the diameter of the screws. For example, if the size of the screws is M3.5, the distance between the screws should be greater than or equal to 3.5mm.

In conclusion, the size of screws used for light steel keel depends on the thickness of the steel plate. Generally, the size of the screws used is M3.5-M5.5. When installing the screws, it is necessary to pay attention to the distance between the screws, which should be greater than or equal to the diameter of the screws.
