About LSF - Light Steel Framing
Structural safety is probably the aspect that the future user will quickly think when examine the possibility of constructing a building with a steel structure. The fact of using lightweight materials, in contrast with concrete weight, can lead many to question the resistance of that kind of constructions.
Speed of Construction - Given that materials used in LSF construction are usually more expensive than those used in conventional construction, is precisely this characteristic that makes this constructive solution accessible and competitive. Clearly time and labor are deeply connected with the final cost of the construction.
OSB is a product of high mechanic resistance, ecologically friendly, enduring, versatile, and with qualities absolutely uniform, that definitely change its concept of structural panels.
Metallic profiles used in Light Steel Framing constructions are manufactured from galvanized steel sheets covered with zinc by the continuous process of hot dip galvanization, which acquire their final shape through an industrial process of shaping or cold molding that can be in form of U, C, omega and L. This process aims to ensure the durability of the elements for hundreds of years.
The word steel refers to raw material used in the structure, the steel.
The inclusion of light indicates that steel elements are underweight since they are produced from steel sheet with reduced thickness. In order to focus that characteristic many publications utilize the term light gauge (gauge is a unit of measurement, now almost into disuse, which defines the thickness of metal sheet).
Others describe steel as cold formed steel, being this molded steel or cold shaped, as reference to sheet molding process through mechanic processes at room temperature, such as bending or lining up.
