LGS stands for Light Gauge Steel. This technology uses lightweight steel frames and is new in India. It offers several advantages such as speedy construction and erection, cost savings, etc. The steel skeleton for a small house can be produced in the factory and erected on site all within a short time frame of 1-2 weeks. The structure is then cladded on both sides by metal sheets or Magnesium/Gypsum boards and insulation depending on usage. The resulting structure is weather and earthquake resistant. Applications include partition walls, low-cost housing, security cabins, small sheds and more.
Light gauge steel construction is very similar to wood framed construction in principle - the wooden framing members are replaced with thin steel sections. The steel sections used are cold formed sections (formed or given shape at room temperature). This is in contrast to thicker hot rolled sections, that are shaped while the steel is molten hot. Cold formed steel is shaped by guiding thin sheets of steel through a series of rollers, each roller changing the shape very slightly, with the net result of converting a flat sheet of steel into a C or S-shaped section.
