Why Triax?

The Triax system eliminates a lot of the hassles often experienced during the design, manufacture and installation of waterproof shade structures. The Triax system is easy to use and most of all, it gives you - the architect, builder, designer or installer - freedom to create individual and customised designs.

The Triax system allows two crossing pipes to be joined together permanently, without welding, without special tools and without the need to rely on precision critical measurements.

Triax structures can be wall-mounted, roof-mounted or freestanding on posts. The tension of the membrane cover is not transmitted to the mounting points, instead being contained within the frame itself. This means that unlike with traditional membrane covers, the structural integrity of existing buildings is not compromised by the addition of a Triax structure.

The Triax system is so adaptable, difficult site restrictions can be overcome and minor design modifications can be adopted if and when they occur.

Gutters, drop blinds, heaters, lighting and ventilation can all be added to structures with the Triax system. In many cases, wiring can be fully concealed by running it within the structural members themselves.

Anatomy of a Triax Structure

The bearers on either side support the rafters. The spreader bar prevents the rafters from rolling in under the tension of the cover. With Triax system's couplings you can achieve a span of up to 6m between supporting bearers, which do not need to be level or parallel.

Two Triax T50 brackets bolt together back-to-back to form an adjustable coupling for 50NB pipe.

T50 brackets are also used individually to anchor the bearers in place - bolted to the top of a post, the side of a wall or any other suitably resilient existing structure.


When installing, the rafters and Triax couplings are strapped in place before being permanently fixed with Tek screws. This allows the installer to check that the rafter is in the correct position and plumb, and adjust if necessary.

FX50 brackets can be used in place of the double T50 couplings if the pipes are crossing at 90° to one another.

EC50 end caps are used to provide an anchor point for the membrane cover at the end of each rafter.

PC80 brackets are used to cap 80NB pipe and provide a clean-looking, structurally sound anchor point when attaching a bearer to the top of a post using a T50 bracket.
