LGSF (Light Gauge Steel Framed System) prefabricated building technology uses cold-formed galvanized steel profiles. It is lighter in weight, factory-made, and assembled at site. The infill is usually lightweight concrete/Rockwool in combination with Cement Fiber Boards on both sides. The floor and roof can be RCC, steel truss, or steel deck.
