How are cold-formed steel studs/track manufactured?

Large ‘coils’ of sheet steel are loaded into machines that first slice the steel into the necessary widths. A 600T125-43 track would be cut into something close to 8-1/2” wide. These smaller strips are rolled into smaller coils and fed into a rolling machine. Through a series of progressively positioned rollers, the fed steel is slowly shaped by bending the flanges over. The first set of rollers might bend the steel 5-degrees. The second set might bend it to 10-degrees. Eventually, the final roller will bend it to a 90-degree angle. Different cross-sections will have different roller positions to create that specific shape. Lastly, the steel is cut to length and bundled with other members for shipping.
