Light steel structures are a dynamic and innovative steel construction system, one of the more common structural forms in modern building engineering, and have been widely applied in areas such as sports venues, office buildings, and warehouses. In recent years, their use has also been promoted in residential construction. The prominent advantages of light steel structures include fast construction, good structural performance, and excellent seismic resistance. We use mechanical fastening to fill the wall frame of the light steel structure, making it the ideal combination, ensuring the entire construction provides thermal insulation, fire resistance, soundproofing, and waterproofing.
