Light Gauge Steel (LGS) is typically thin sheet (generally 0.5mm to 1.5mm thick) of high grade steel that is roll formed into various shapes and sizes for construction. From the word “Light” due to its weight but high tensile steel sheets. They are very thin plate elements compared to their widths. They are generally 0.5mm to 1.5mm thick and are developed through a Cold Form Process so it is also cold formed steel. NB: When a Steel Cold formed Yield point and Strength increases, ductility decreases, fatigue strength increases and especially in the bent corner.
The studs can be joined together to form frames or webbed joints which are used as walls and floors. Thus, in addition to roof truss framing and other bracing components, a complete
structure can be constructed using this technology although structurally, Light Gauge Steel (LGS) structures do tend to have a height restriction depending on the gauge and profile of steel used.
