Basic description of light steel keel

Thin-walled light steel keel is a new type of skeleton material that uses steel instead of wood. It is combined with light-weight plates to form a wall or suspended ceiling. It does not require wood or cement. It changes the traditional wet operation to dry operation, and is flexible and easy to disassemble. With light weight and high strength, it can adapt to various requirements such as shockproof, fireproof, heat insulation, sound insulation, etc. This composite wall has characteristics that cannot be achieved by traditional brick walls and other walls, so it is in Japan, the United States, etc. Industrially developed countries have begun large-scale adoption. China has also begun trial production with the efforts of relevant units since the early 1970s, and has achieved significant economic benefits in some engineering practice applications.
