Francis and Lewis International Ltd

Material Supplier

Mild steel fabrication of structures and components, including platforms, towers, brackets, frames and walkways.


FLI is a specialist fabricator of steelwork packages for nuclear build projects that use repeatable designs in high volume for rollout work packages. Bespoke and special designs are also available for secondary steelwork packages. FLI’s design & detailing teams are used to formalising outline designs from concept to fully detailed, fabrication ready solutions.

Approved to BS EN 1090-1 & 2, with welders qualified to BS EN 9606-1 and all procedures to BS EN ISO 15614-1, with complete in-house design, project management, manufacturing and installation capabilities. We have automated production lines for beams, angle, tube and plate, along with welding robots and presses to 300T. Processes include submerged arc, MIG, MMA and stud welding, fabricating mild steel to Execution Class 4.
FLI has a history of supplying products for substantial call-off contracts, for rail electrification and mobile phone technology with our designs forming over half of the UK network. We also design innovative solutions to our customers' problems, such as challenging ground or site conditions or a need to deliver very fast design and build, to developing designs which improve programme reliability.
We work closely with our customers to deliver what they want. Our track record in quality backs up this approach, with quality control producing a defect rate below 0.04% (against a 3% industry average) and a Health and Safety culture and record recognised with the ROSPA Gold Award, our systems exceed normal industry standards.
