Metal Stud Framing
Commercial drywall using light weight metal stud framing as the primary material. Metal studs have several distinct advantages over wooden studs. They are lightweight, cleaner (no sawdust when cutting), easily moved if need be since they are attached with fasteners instead of nails.
Metal studs will not warp, are immune from insect damage, such as termites, and finally are environmentally friendly since they do not require cutting down trees as wood studs do.
