SW Channel & Ties

The SW channel and tie system is used to restrain masonry back to steel studwork.

The SW channel is fixed through the insulation back to the steel studwork using self drilling, self tapping screws which have a under head high thread, which offers maximum
support to the channel but prevents compression of the
insulation material.

SW ties can be inserted at any point along the channel length and built into the masonry bed joints.

Please contact: G.A. Fixings for specific advice on the type of fixing screws required for each application.
