What MultiSteel does
MultiSteel is a London-based, family-owned specialist manufacturer and installer of bespoke steel security doors and architectural metalwork, founded in 2002 by brothers James and Terry Horan. The company operates from a single North London facility in Harrow where it designs, fabricates, and installs three core product lines — communal entrance doors, external bin store doors, and heritage-compliant steel security doors for Grade I, II*, and II listed properties — complemented by architectural metalwork, powder coating services, and estate-wide gate systems. Technical differentiation rests on in-house manufacturing using high-grade European steel (including Jansen Swedish steel for select projects), concealed twin or triple Assa Abloy/Securitron magnetic locking systems, multi-stage corrosion protection (shot-blast, zinc prime, polyester powder coat), and compliance with BS 8300-2:2018, Approved Document Part M, and welding standards BS EN ISO 15614-13 and 9606-1.
The company sells exclusively on a direct B2B basis through bespoke project quoting, with no public pricing, no distribution intermediaries, and no retail channels. Primary customers are London local authorities and housing associations (Southwark, Lambeth, Islington), Tier 1 and Tier 2 main contractors on new-build and renovation construction projects, and a secondary segment of discerning private clients requiring heritage-compliant period-property doors. Revenue is generated through one-time product sales and professional services for access control integration, with multi-year contracts and volume discounts on estate-wide installations. The company claims cumulative volumes of 10,000+ communal entrance doors, 4,000+ bin store doors, and 300+ heritage installations, with several reference installations demonstrating 10-15+ years of maintenance-free performance.
Operationally MultiSteel is a privately held single-jurisdiction UK business with no disclosed funding rounds, no parent company, and concentrated ownership with the founding Horan family. In November 2025 it launched a refreshed brand identity and website, signalling positioning evolution from specialist door manufacturer to broader steel security solutions provider, while continuing to anchor on direct local authority relationships in London and extending heritage work nationwide.
