Gilgen Door Systems

What Gilgen Door Systems does

GDUK Door Solutions Limited operates as the UK arm of Swiss-origin Gilgen Door Systems, manufacturing, supplying, and installing automatic pedestrian and industrial door systems, gate and barrier systems, aluminium shop fronts, and security-rated door systems. The company serves commercial, industrial, healthcare, retail, education, hospitality, transport, and public sector customers across the United Kingdom from its head office and manufacturing facility in Alfreton, Derbyshire, supported by a national service network for installation, planned maintenance, and 24/7 emergency repair. The product portfolio spans five core categories — automatic door systems (sliding, swing, curved sliding, folding), industrial doors (roller shutters, sectional, high-speed), gates and barriers, aluminium shop fronts, and security doors — with the SL35 PAS:24 manufactured on-site at the Alfreton facility.

The technology platform centres on proprietary Gilgen-branded door operators (FD10, FD20, FD20-UG, SL35) featuring sensor-driven activation (motion detectors, infrared, RFID proximity, pressure mats), electromechanical multi-point locking tested beyond 500,000 cycles, wind-load compensation up to 80km/h on the FD20, fail-safe spring-actuated closure with battery backup, and integration with access control systems including keycards, biometrics, RFID, intercoms, fire alarms, CCTV, and building management systems. GDUK was the first automatic sliding door supplier in the UK to achieve LPS 1175 accreditation from the Loss Prevention Certification Board (LPCB), and holds Secured by Design approval, PAS 24:2016, BS EN 16005, DIN 18650, EN 1634, FD30/FD60 fire ratings, TÜV-Nord certification, CHAS ELITE, JOSCAR, and BS EN ISO 9001/14001 plus ISO 45001 and BES6001 — establishing a regulatory and compliance moat in security-rated and fire-rated specifications.

Revenue is generated through four streams: (1) equipment and doorset supply including a trade-channel "Simply Supply Only" online configurator with 3-week delivery, (2) installation and commissioning professional services from concept to handover, (3) recurring maintenance contracts starting at £148 for the first asset and £54 per additional asset per site covering all manufacturers and product types, and (4) pay-as-you-go repair services with published pricing between £350 and £7,000. The go-to-market combines direct enterprise field sales with sales engineers managing the full project lifecycle, a self-serve e-commerce channel for trade buyers, content marketing via a news and insights blog, industry event participation (including the International Security Expo), and trust-signal certifications. Maintenance contracts are recommended for sites with 20+ automatic systems, providing recurring revenue retention, while the national service centre provides real-time technician dispatch and 24/7 emergency call-out coverage.

• GEZE UK: UK arm of German automatic door systems manufacturer. Directly comparable product range (sliding, swing, folding doors), target customers (commercial, healthcare, retail), and value proposition (sensor-driven, EN 16005-compliant systems).

• ASSA ABLOY Entrance Systems: Global incumbent in automatic doors, industrial doors, and loading dock equipment under brands including Besam, Crawford, and Megadoor. Competes with GDUK across all major product categories but as part of a much larger portfolio focused on access solutions at enterprise scale.
