Company Profile

• Frangible Approach Lighting Masts

  Exel Composites lattice mast structure ensures the highest possible stability in all conditions. Typically seen approach light masts with pole structures cannot reach similar stability features.

  Carefully designed lattice structure is assembled from very thin wall glassfibre tubes, providing the lowest possible weight.

  In addition to light weight, stable glassfibre structures guarantee the best performance in extreme weather conditions and lasting performance in corrosive environments.

  Exel Composites lattice masts are fully tested under witness of independent third parties (NLR, Intertek) to prove compliance with ICAO and FAA frangibility requirements.

  As ICAO’s frangibility requirements only apply to the top 12 meters of the mast, Exel’s lattice mast clearly exceeds these requirements by being frangible throughout full height of the mast.

  Lattice masts are available from 1,8 meters to 35 meters.

  

• Frangible Weather Mast/Anemometer Mast

  Exel Composites masts are full scale impact tested according to the Aerodrome Design Manual Part 6, chapter and FAA AC 150/5345-45C, section 4

  • Exel lattice masts provide an excellent base for installation of various weather monitoring instruments. The firm but lightweight structure is available in a wide range of heights to cover practically any type of installation and ground condition.
  • The standard colouring scheme is orange/white in seven sections, as specified in Annex 14. Other colouring schemes are available.
  • The most typical installation interface for the weather instruments is a spigot at the top of the mast. Other interfaces are available upon request.
  • The mast is supplied with tilting from the base as standard. For taller masts an option of centre hinge is available.

  Built-in Frangibility:

  • Built-in frangibility—no break-away points needed
  • Rigid lattice structure of glassfibre material
  • Transparent to electromagnetic signals
  • Easy installation
  • Maintenance free

  • Bottom hinged mast is best suited for airports having the utility of an access platform. Servicing of the instruments can be done from the basket of the platform without lowering the mast down.
  • Centre hinged mast can be tilted down by one service  person for easy maintenance
  

• Frangible Glide Path Tower

  Exel Composites has developed a unique range of fibre glass lattice towers which have been delivered to airport installations since 1988.

  Fibre glass is a lightweight material that brakes at impact and is transparent to electro-magnetic signals. It tolerates all types of weather and is practically maintenance free.

  GP-Tower delivery includes anchor bolts and casting template, sub-assemblies for on site assembly of tower sections, antenna brackets that allow adjustment of antennas both vertically and horizontally, cable conduits, ladder and safety rail and obstruction light.

  

• Frangible Airport Fences

  AERODROME DESIGN MANUAL PART 6, Frangibility – First Edition, 2006 states that: 1.3 OBSTACLES TO BE MADE FRANGIBLE

  …certain airport equipment and installations, because of their function, must be located in an operational area.

  All such equipment and installations as well as their supports should be of minimum mass and frangible in order to ensure that impact does not result in loss of control of the aircraft.

  Among these equipment are for example fencing.

  Exel airport fences are full scale tested to prove compliance with ICAO’s frangibility ruling for approach support structures.

  Delivery of Exel frangible fence includes panels, posts with panel clamps, cross-pin for bottom of post for setting in soft ground, corner connectors, gate with two hinges, locking plates for padlock and an illustrated installation manual.
