Patterns:
It is possible to add pattern to the mast eg camouflage.

Ease of Installation

  • Lightweight
  • Quick and easy to install
  • Reduced installation time
  • Hinged base option to facilitate easy testing and inspection
  • Three mounting options available – direct burial, hinged and free standing base

Durability

  • Composite high strength material
  • Corrosion resistant
  • UV protected
  • Vandal resistant – mechanical damage and graffiti
  • The composite mast itself, does not cause interference for radio, microwaves, etc . . .

Safety

  • Glass-polyester composite construction – an insulating material
  • The mast does not absorb energy in the event of a vehicular collision

Flexibility of Selection

Our lightning mast can be customised to customer requirements.

The Kingsmill Lightning Mast allows the user flexibility not only to choose either aluminium or copper air terminals and conductor, BUT also, select one or two down-conductors as well as vary cross-sectional area.

Not only are there three standard colours to choose from:

  • White
  • Pebble Grey (RAL 7032)
  • Kingsmill Grey (RAL 7042)

. . . but we can offer other colours as well as customer specific pattern and graphic effects too.

Product Selection

Wind loading and location of the masts are key elements in determining the type and size of foundation/base that can be used. It is important therefore, that Kingsmill carry out calculations to verify correct foundation selection.
