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.

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.

FLI 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.
