Where every Fort Engineering door, window, safe room, and shopfront is fabricated. 10,000 square feet on a single Luton site, 35 people, most of them five or more years in.
If you’re here, you’re probably a specifier or a procurement team trying to verify the manufacturing claim before signing it off. The factory is real, it’s at the address further down the page, and what follows is a description of what happens inside it.
One site, one operation. Nothing is sent out for fabrication and brought back. Steel comes in at one end and certified, finished, hardware-fitted doorsets leave at the other. Every stage between – cutting, welding, finishing, hardware, QC – happens in our own bays.
We don’t run factory tours. The rest of this page is the next best thing. If you need more than this to validate the manufacturer, the certifications and case studies pages are where to go next.

The site
The factory started smaller than it is now. We’ve expanded twice on the same site as production volumes grew, taking the floor area to 10,000 square feet of fabrication, finishing, and dispatch space.

Inside
Steel comes in at one end. Certified, finished doors leave at the other. The path between is described below, in the order the work actually runs.
FE/FAC-03
01 / Zone
Intake
British-sourced steel sheets and structural members arrive at the bay nearest the road. Each delivery checked against the purchase order, mill certificates filed, and grade-tagged before anything moves further into the factory.
FE/FAC-04
02 / Zone
Cutting
Laser cutting for sheet, CNC bending and press brake work for forming. Tolerances measured in tenths of a millimetre – LPS 1175 doesn’t tolerate “close enough”. Cut steel moves on trolleys to the welding bays, not forklifts dragging half-fabricated assemblies through finished-goods areas.
FE/FAC-05
03 / Zone
Welding
This is where most of the security work actually happens. Welders working to ISO welding standards, frame and leaf assemblies built up component by component. The welding is what makes an LPS 1175 SR3 doorset an SR3 doorset, rather than an SR2 with extra paint on top.
FE/FAC-06
04 / Zone
Finishing
Galvanising where the corrosion class demands it, powder coating across the standard range. Powder is preferred over wet paint: lower VOC emissions during application, recoverable overspray in the booth, more durable finish on a product the customer expects to last thirty years.
FE/FAC-07
05 / Zone
Assembly
Locks, hinges, closers, vision panels, anti-ligature ironmongery. Built up onto the finished steel. Every hardware spec on a Fort Engineering doorset is tied back to the relevant certification – the lock cylinder on an LPS 1175 SR3 doorset isn’t a “near enough” choice, it’s the one the test certificate names.
FE/FAC-08
06 / Zone
QC
Dimensional checks. Coating thickness measurement. Visual inspection. Test fitting against frames before either ships. This is in-house quality control, not certification testing – LPS 1175, LPS 1056, and FB4 ballistic testing happens at independent UKAS-accredited facilities, not on our premises. Both matter; they do different jobs.
FE/FAC-09
07 / Zone
Dispatch
Each finished doorset is wrapped, crated, and labelled with the project reference, the cert number, and the customer brand it ships against. Loaded for road transport. The four customer brands handle the fitting via their own teams.

Handoff
Fort Premium for residential. Magnificent Security for HNW London. Sash Vault for heritage. Fort Security Doors for commercial. The factory makes everything. The four brands sell, fit, and look after the customer.

The people
The factory runs on 35. Welders, fabricators, finishers, assemblers, QC, dispatch, plus the design and admin side. Long enough on the bays to know the standards by feel, not just by reading them.
We work to ISO welding standards across the welding bays. The codes themselves matter to procurement teams; what matters to the doors is that the welders running them have been at it long enough to know what a sound weld looks like before anyone runs a test on one.
Apprentices come through the bays too. The factory works because the next generation of fabricators is being trained on the same standards, by the people who set them. If you’re interested in working here, the careers page covers what’s open.

Verification
We don’t run tours, but specifiers and procurement teams still need to verify the manufacturer before specifying the product. Three routes that work without anyone needing to drive to Luton.
01
The factory is audited annually as part of our ISO 9001:2015 scope. LPS 1175 and LPS 1056 certifications include a factory production control element. All five certifications are listed with cert numbers, issuing bodies, and live verification links.
02
Recent case studies cover SR3 data centre projects, BB67 lockdown classroom doors, SR4 utility enclosures, and ballistic-rated installations. Each one names the manufacturer, the certification cited, and the customer brand that handled delivery on site.
03
We don’t run factory tours but we do have video clips of individual processes – cutting, welding, finishing, QC – that we share with specifiers and procurement teams on request. Drop us a line about a live project and we’ll send the relevant clips.
