Light-gauge steel framing
Light gauge sheet steel Cold-formed to shapes that mimic wood light frame
members Almost always hot-dip galvanized Light weight Noncombustable
Primary uses Interior partition walls (Type I & II Construction) Exterior nonloadbearing walls (Type I & II Construction) Increased use in loadbearing applications where WLF has
traditionally been used High seismic areas Warm-humid areas (termite & mold prone areas)
