Cold-formed steel (CFS) is a general term for steel products shaped by cold processes near room temperature, such as rolling, pressing, stamping, bending, etc. Stock rods and cold-rolled steel sheets (CRS) are widely used in all areas of production. The terms differ from hot-shaped steel and hot-rolled steel.

Cold-formed steel, especially in the form of thin steel plates, is widely used in the construction industry for structural or non-structural elements, such as pillars/columns, beams, studs, floor covering (intermediate floors), embedded sections, and other components.

Cold-formed steel elements have also been used in bridges, storage shelves, solar energy systems, conveyor lines, car bodies, railway rams, highway products, transmission towers, transmission poles, drainage facilities, various equipment types, and in many others. In roll-forming machines these types of compartments are cold-formed by pressing or bending processes from steel sheet, strip, plate or flat rod. Material thicknesses are usually between 0.50 mm and 6.00 mm for these fine-walled steel elements.

Advantages of cold forming;

- Lightness
- High strength and rigidity
- Ease of prefabrication and mass production
- Quick and easy to assemble and assemble
- Significant elimination of air-related delays
- More accurate detailing
- No shrinking or creeping at ambient temperatures
- No mold required
- Termite-proof and decay-resistant
- Uniform quality
- Economy in shipping and transport
- Non-flammable
- Recycled material
- Panels and platforms can provide closed cells for pipes.
- A broad classification of cold-formed shapes used in the construction industry can be done as individual structural framing elements or panels and decks.

Some of the popular applications and preferred sections:

- Roof and wall systems (industrial, commercial and agricultural buildings)
- Steel shelves to support storage pallets
- Structural elements for plane and space scissors
- Stressed skin structures without frames: Corrugated sheets or hardened edge layer profiles are used for small structures up to 9 m opening without an inner frame.
