Applications
Residential Light Gauge Steel Framing
The LG2019 is commonly used for light steel framing in low-rise residential projects, including houses, villas, and townhouses up to 1–3 storeys. It produces wall panels, roof trusses, and floor trusses with stable forming accuracy, helping ensure reliable structural performance in prefabricated housing construction.
Commercial Interior Partitions & Wall Systems
This machine is well suited for commercial building applications such as offices, hotels, schools, and retail spaces. It manufactures steel studs and tracks used in interior partition walls and non-load-bearing systems, supporting efficient drywall installation and faster on-site construction progress.
Modular & Prefabricated Building Systems
LG2019 is also widely applied in off-site and modular construction projects. It enables efficient production of steel framing components for prefabricated housing units and temporary buildings, helping reduce on-site labor requirements while maintaining consistent component quality for rapid assembly.
