Telegraph Pole
The FLI Telegraph pole provides the
opportunity to place smaller structures,
ideal for micro sites, into Greenfield
locations with minimal aesthetic impact.
The pole is a CHS tube up to 16.5M, with
painted
effect, mimicking the colour and graining
of a treated timber telegraph pole. This
simple design offers you a quick, cost
effective solution to difficult sites, and
is ideal for all Greenfield areas and on
streetwork sites.
The Telegraph pole can also be supplied
with a CHS root foundation to minimise
the size of the foundation.
We can install studs for Latchway
removable climbing rungs, or brackets
to support a Metreel removable ladder if
required.

Guyed Masts
FLI have a large selection of parallel structures designed for guyed mast applications.
These include the Unimast products with their fully welded construction, integral
climbing rungs, each 3m long section is light enough to be carried and capable of
reaching heights of 85m. The FLI series ranges from the FL85 to the FL250 with 2.5m
wide and 7m long sections capable of being installed to a height of 300m.
Though guyed masts are not common due to the large amount of land required, they
are the most cost effective way to support equipment at height.

Radar Towers
Our radar towers have been installed all over the world, including the UK, Europe,
Africa, South America, South East Asia and the Middle East. This has involved
designing highly stressed structures for climates varying from Tromso in Norway,
which is well inside the Arctic Circle, El Diego Garcia in the Indian Ocean and Harare
in Zimbabwe. The deflection limits on these types of structures are very low and the
radar loads are high. Hence the frame of the cabin is a major structural element,
transferring the radar loads to the tower.
Specification:
· Height: 5m - 30m, in 5m increments.
· Site specific heights available.
· Suitable for primary and secondary
radar antenna.
· Radome interface options.
· Waveguide support.
· High level equipment enclosures.
· Lightning finials according to specification.

Bespoke Structures
FLI’s staff enjoy designing & manufacturing new products. We can provide a bespoke
service very economically because, unusually for a steelwork manufacturer, we
employ innovative chartered engineers who can help you to find the right solution
for your site. We can even provide an accurate 3D visualisation of your structures to
illustrate the visual impact of the proposals on the surrounding area. You and the
planners can therefore be totally sure of what you will be getting before we make
anything.
We are happy to offer you alternatives and to work with a range of materials to
suit your needs. We can provide a turnkey solution including foundation design
and installation of the structure. These structures are ideal where there is an urban
regeneration programme in place.
