25/15 Framefix Ultra Channel

ACS developed the 25/15 Framefix Ultra Channel in response to the increasing need to tie masonry cladding back to steel framed structures.

Supplied in 2700mm lengths, the ACS 25/15 frame fix channel system is pre drilled at 112.5mm centres and is also complemented by the 4000 range of channel ties.

In addition to this, ACS also offer a range of both stainless and zinc plated fixing screws. The design of these screws specifically hold the channel in position. They do this whilst not crushing the composite material, along with drive units for the installation of the screws.

Sheffield Hallam University’s Department of Structural and Civil Engineering have supported the 25/15 channel system through independent testing.

Technical Data

ACS Frame Fix Ultra is designed for tying a masonry panel back to steel studding posts. The channel is fixed back to the studding using self-drilling/tapping Tech Screws fixed through the channel and insulation material, into the steel studding. The channel is fixed back to the structure via the pre-punched holes at close centers to allow the fixing point to be selected depending on the application. Once fixed, ACS 4000 range wall ties can be positioned at any point along the channel to suit the coursing of the masonry panel

The Ultra Steel advanced material forming process has been extensively tested and developed and its integration into the manufacture of the 25/15 channel provides a range of performance enhancing benefits, including:

Added Strength, Increased Load Carrying Capacity, Reduced Deflection, Increased Memory & Spring Tension, Improved Acoustic & Thermal Benefit, Improved Fire Test Performance
