Framework Supplier

FLI is a Network Rail framework supplier for overhead line electrification steelwork for projects across the UK. With production lines and procedures tailored to OLE project delivery, we have capacity exceeding 200 masts and 100 booms per month. Our engineers have worked with Network Rail to introduce efficiencies to existing designs and developed new solutions, including the Flexi-Pile Cap and Offset Foundation Beam.

Masts and Booms

FLI manufactures all masts and booms from Series 1, Series 2 and the Master Series, including the 27m Mid Point Anchor Booms supplied to the Greater West programme. Our output defect rate is just 0.01% (in 2018 against a 3% industry average), significantly reducing on site delays.
