Lightweight Lightning Mast
Kingsmill bring innovation to Lightning Protection through the introduction of a lightweight, easy to install, aesthetically pleasing Lightning Mast.
Suited to projects using the “protective angle” or “rolling sphere” method for determining zones of protection.
Complies with the safety and wind loading requirements set out in BS-EN 40-7.
No unsightly guy wires or supports.
Three standard colours, but we can offer other colours subject to RAL code.
It is possible to add pattern to the mast eg camouflage.
Ease of Installation
- 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
- 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 . . .
- 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:
- Pebble Grey (RAL 7032)
- Kingsmill Grey (RAL 7042)
. . . but we can offer other colours as well as customer specific pattern and graphic effects too.
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.

The type of base offered is dependent on wind-loading and other operational conditions.
Zone of Protection
An air terminal or mast affords a protective cone.
|Height above reference plane|
A sphere is rolled over the building. Where it touches, protection is required.
