Steelguard

What Steelguard does

Steelguard Limited is a New Zealand-based custom manufacturer of steel windows and doors, headquartered at 50 Porana Road in Wairau Valley, Auckland (Glenfield factory). Founded in 1985 and operating for over 40 years, the firm produces architectural, fire-rated (EI30/EI60/EI90), security, and heritage steel joinery from hot-rolled and cold-rolled steel sections using CNC machining, hand assembly, and precision welding. It serves residential, commercial, hospitality, civic, correctional, and heritage restoration projects, with products installed across all New Zealand prisons, numerous police stations, courthouses, mental health facilities, and landmark buildings including NZICC, Horizon Hotel, 1 Queen Street, Te Matapihi Central Library, Dilworth Building, and the CPO Britomart heritage refurbishment. Core technology layers include in-house CAD (AutoCAD, SolidWorks) with BIM Level 2 integration, FEA structural analysis, PS1/PS2 producer statement issuance, on-site E2 water leakage testing (WGANZ 501/502), and a heritage hardware library with reproduction via lost-wax casting. Steelguard operates as the Australasian agent for Jansen's steel profile systems (Janisol, Jansen-Economy, VISS) and Vetrotech Saint-Gobain's fire-resistant glass, partnerships spanning over 30 years.

The business runs a sales-led, project-based B2B model addressing architects, builders, main contractors, heritage consultants, and government procurement. Two engagement structures coexist: a supply-only option where Steelguard manufactures to client specification and delivers to site, and a full turnkey service spanning design, survey, manufacture, installation, and commissioning. Pricing is quote-based with 30-day validity, payment by the 20th of the following month, and 2.5% monthly interest on overdue balances; PS1/PS2/PS4 producer statements are billed separately unless explicitly quoted. Revenue is generated across four streams: custom steel window/door manufacturing (one-time), installation and commissioning (professional services), maintenance and refurbishment (managed services, including phased heritage restoration), and design/engineering consultancy. Distribution is purely direct — no retail, e-commerce, or reseller channel — supported by public tender participation, preferred-supplier listings with main contractors (e.g., Bracewell Construction, CMP Construction), and repeat architect referrals.

The competitive position rests on regulatory and specification lock-in: serialised fire tags, BRANZ endorsements, BPIR documentation, and WSP-lab-tested security systems combine with 40+ years of specialist know-how and an extensive heritage parts inventory. Customer concentration skews to New Zealand institutional buyers — particularly the Department of Corrections — alongside Australian cross-border work such as Chanel Melbourne. The firm is privately held with no disclosed funding rounds, no parent company, and Director Chris as a 15-year shareholder. Marketing is indirect, driven by project portfolio, an active news/blog, and social channels (Facebook, Instagram, LinkedIn), with no paid digital advertising or self-service motion.
