RA2000 RANGE

This range offers versitile custom made glazing solutions in a choice of Tubular, I or Box profiles.

Our tubular bar section offers softer sight lines and adds depth and elegance to overhead, vertical and atrium glazing.

Our "I" profile bar offers the advantage of a 4 edge support system coupled with the minimal sight lines asociated with traditional patent glazing.

We offer a choice of 65 or 50mm wide box sections withing the RA200 range which can be secured to the structure using wither a fixing shoe or angle cleats.

The web of the I and tubular profiles may be slotted for added effect.
