What is Light Gauge Steel Frame?
The steel comes in sheet rolls up to a gauge of 2mm. It is then put through the roll former where it is cut to length and formed into shapes and sizes that are similar to those in timber frame but with a much higher strength to weight ratio. Steel frame members are formed in a process called roll forming by passing sheet steel from a coil of steel through a series of rollers to form bends to make the shape of a stud or ‘C‘ shape. Because the process is done without heat i.e. cold formed, the shaped steel is stronger than the original sheet steel. The computer controlled rolling allows, at the same time that the steel is rolled, the fixing of holes, service holes and locating flanges to be punched and positioned to the exact engineered position that the designers have determined to ensure that the panels or joists are to the precise dimensional requirements of the project.
