METAL STUD FRAMING
Cold-formed steel elements are used to build structures and other surfaces in typically made of steel stud framing. A stud and a rail are the two primary parts of a metallic stud frame.
Studs and tracks are the two main parts of a steel frame. The top and bottom plates are made of the track. Lay up your walls and openings for metal stud framing the same way you would for wood, but when installing the bottom plate, avoid running the track over the door openings.
