Steel framing sheets are passed through a series of rollers and steel is bent to create a more useful shape for the building, such as flanges, web, and the lip of the stud or C-shape. Steel frames come in many shapes and sizes, such as 2×4, 2×6, 2×8, 2×10, etc. You can find more about frame supported structure via https://quickframes.com/
The length is custom cut in the steel plant. And, since no heat is used to make steel, no integrity or power is lost. The shape makes the frames more powerful than the original sheet. Steel frames can either be sold as it is or placed into configurations to be sold as wall panels.
Imagine the wood framing of a traditionally constructed home, but where there are 2x4s, 2x6s, etc., there are steel studs. The studs themselves start out as large steel sheets.
Because steel is so strong, durable, versatile, and affordable, can be used as framing for a wide range of situations, from the superstructures such as skyscrapers, bridges and high-rises to lower-scale building projects like commercial shopping centres and residential homes.
Since the ratio of power-to-weight of steel is so high, it is ideal for situations that require long spans. For example, steel opens up possibilities for wide, open living spaces in residences.
