Wagners Composite Fibre Technologies (CFT) manufacture three standard crossarm profiles sizes; 125x125mm, 100mm x 100mm and 100x75mm. These sizes were developed to closely align with traditional timber crossarm sizes for ease of fitment into existing networks. All Wagners CFT crossarms are coated with a co-extruded thermal plastic alloy that has been rigorously tested against the effects of electrical tracking and UV protection.
The Wagners CFT crossarm design is a square or rectangle hollow ore section and does not include any fillers such as foam. While the Wagners crossarms do not contain filler material, the use of glued inserts ensures the product is completely water tight.

There are five durability parameters to be considered when investigating the design life of a product or materials including:
- Resistance to attach by physical agents
- Form and dimensional stability
- Permanence of adhesives and mechanical fastening systems
- Resistane to corrosion
- Resistance to fire damage
The Wagners crossarm performs extremely well regarding all the above factors which leads to a typical design life of 40-years for most locations and environments.

Fibre Reinforced Polymer (FRP) components can experience loss of stiffness when their temperature rises above their ‘heat distortion temperature’ or HDT. the HDT of an FRP is based on the resin type used and the treatment that the resin has undergone. Wagners pultrusion process occurs at a temperature of 150C. For any relaxation (loss of stiffness) to be seen the temperature of the element must be elevated above 150C.

Wagners CFT is very proud to have achieved the highest level of products and service which is evident in the continuous certification of the company under ISO9001. Quality control documents and tests in conjunction with a production Inspection and Test Plan (ITP) have been developed in house to create a stringent QA system to ensure the highest level of manufacturing quality in all Wagners products.

It is not expected that any maintenance is required on the Wagners FRP crossarms over its design life. Many years of research and development in the design and manufacture of a Wagners crossarm ensures a product that is durable with no maintenance required throughout its service life. Damage to the crossarm caused by outlying environmental and human factors such as fire, storms, transport damage may be repairable.

Wagners CFT crossarms have the availability for bolt holes in a variety of sizes. The typical bolt diameters that are included on crossarm designs are; 16mm, 20mm and 24mm. All Wagners CFT crossarms will be supplied with anti-crush inserts that have been glued in place using a high strength polyurethane adhesive.

Wagners CFT supply all crossarms with batch numbers permanently engraved on all endcaps (which are secured for their design life). These batch numbers are used to help trace back all relevant data including, but not limited to the raw material purchases and relevant Certificate of Analysis, quality control batch testing results, completed QA forms and documents, client purchase orders etc.

Wagners CFT crossarms pfovide increased grid reliability; they are strong, lightweight, non-corrosive and dielectric and coated with durable finish. According to our customers, our crossarms as easy to install as they are pre-drilled and light to handle at heights and that paramount for a safer installation. We are AS7000 compliant and engineer crossarms to meet and exceed customer requirements.
