Material Properties - Steel in Residential Construction.

The galvanized strip steel from which the light steel framing is formed is usually designated as either grade S280GD or grade S350GD to BS EN 1014710 (formerly Fe E 280 G or Fe E 350 G). These designations indicate the yield strength (280 or 350N/mm2 ) and the fact that the material is galvanized with a minimum G275 coating. Cold formed steel sections are usually rolled from galvanized sheet steel that is typically 0.9–3.2mm thick. The normal thickness of zinc coating (275 g/m2 ) has excellent durability for internal applications. Heavier coatings are available for more aggressive external environments.
