LGSF stands for Long-Span Gravity-Defying Framing, which is a construction technique that uses steel frames to build structures with large clear spans, high ceilings, and column-free spaces. It is commonly used to construct steel-framed buildings such as industrial sheds, commercial structures, sports facilities, and other types of buildings that require large interior spaces without intermediate columns. LGSF is known for its ability to provide an open, flexible floor plan, high levels of durability, and resistance to environmental elements like wind, earthquakes, and fire.

LGSF stands for Light Gauge Steel Framing, which is a building construction method that uses thin sheets of steel to create the structural frame of a building. LGSF projects are buildings that are constructed using this method. The use of light gauge steel provides several benefits such as increased strength and durability, faster construction times, improved energy efficiency, and reduced waste compared to traditional building methods.
