USG Shaftwall
Mill Steel Framing is a licensed manufacturer of the USG Shaft Wall system. USG Shaft Wall Systems are non-load-bearing gypsum wall partition assemblies constructed from outside the shaft at each floor. Shafts are enclosed early in construction, and the walls are finished later, along with interior partitions. Installation is quick and easy, using components and application procedures familiar to drywall contractors. This system installs faster than other multilayer gypsum panel systems because it is installed from one side, leaving the shaft free of scaffolding. The assemblies are constructed of gypsum liner panels friction-fitted into C-H studs in a progressive manner, with gypsum panels, gypsum fiber panels or cement board applied to the face.
