ACS 25/15 Bricktie Channel

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 ties can be positioned at any point along the channel to suit the coursing of the masonry panel.

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 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 o Improved Acoustic & Thermal Benefit o Improved Fire Test Performance 

Installation

The channel should be fixed back to the studding which is normally set at 600mm horizontal centres; ties can then be positioned at any point along the length to suit the mortar joint at the specific vertical centres required. (Nominally 450mm)

Frame Fix Ultra Load Capacities

The channel is designed as a point loaded beam with partial fixity at the fixing points. By adjusting the fixing centres the allowable load per tie is increased or reduced.

Fixings Screws

The ACS 25/15 Frame Fix Ultra Channel is designed to fix to the studwork at 450mm vertical centres. The pre-punched holes in the rear of the channel are spaced at 112.5mm so a fixing can always be positioned near the end of the channel. Self-tapping screws can be supplied to accommodate for fixing through insulation board of up to 90mm.

ACS can supply either stainless steel or galvanised screws for fixing the channel back to the structure.

The opening in the channel will readily accept a standard drive socket and fixing.
