Steel frame
Encyclopedia : S : ST : STE : Steel frame
Steel frame usual refers to a building technique in which a skeleton of frame of steel is constructed to support the building which is attached to the frame. The development of this technique made the development of the skyscraper possible.
The framing members are C-sections with standard dimensions similar to wood framing studs.
Steel mills produce galvanized sheet steel, the base material for steel members. Sheet steel is roll-formed into shapes used for framing. The sheets are zinc coated (galvanized) to prevent corrosion. Although there are a variety of shapes available, the primary shapes used in residential construction are the C-shape stud and the U-shaped track. Framing members are generally produced in thickness of 12 to 24 gauges with 3-1/2” and 5-1/2” widths. Steel framing provides excellent design flexibility due to the inherent strength of steel, which allows it to span longer than wood, and also resist wind and earthquake loads.
