Franke Onsrud Blikkslageri

What Franke Onsrud Blikkslageri does

Franke Onsrud Blikkslageri AS is a privately-held, family-owned Norwegian sheet metal contractor founded in 1929 and headquartered at Kjelsåsveien 170, Oslo, with a dedicated department serving the Romerike region. The company specializes in exterior building envelope work — metal facades, roofing, gutters, downpipes, flashing, snow guards, and roof safety installations — for both new construction and rehabilitation, alongside a growing design and interior metalwork practice (Corten steel stairs, railings, custom architectural features). Its core technology is an in-house fabrication workshop equipped with modern machinery for cutting, bending, forming, laser cutting, and powder coating of aluminum, zinc, copper, and stainless steel, enabling custom production of architectural metalwork to architect specifications (zigzag profiles, perforated plates, embossed cassettes). The company employs approximately 60 staff, including administration, sheet metal journeymen, assistants, and apprentices, and is certified as an approved apprenticeship employer (lærlingbedrift).

The company operates two go-to-market motions: an enterprise field sales model targeting large general contractors (Skanska, Veidekke, NCC, AF Gruppen, Viking Entreprenør) and public-sector building owners (Omsorgsbygg Oslo KF, Undervisningsbygg Oslo KF, Bergen kommune, Skatt øst) as a specialized subcontractor or main contractor for technically demanding facade and roofing scopes; and a dedicated service division handling smaller assignments and maintenance for private individuals and SMBs. Revenue is generated through fixed-price, project-based contracts with custom quotes per engagement, typically as part of a general contractor's team on larger projects. Customer concentration is diversified across approximately 15+ named public- and private-sector projects spanning healthcare, education, transportation, sports infrastructure, religious, and commercial real estate.

The company was originally founded by Franke Onsrud in 1929, passed to Hans Onsrud in 1946, then to Franke Onsrud (son) in 1972, and is now led by the third generation — Fredrikke Onsrud as Managing Director and Nina Onsrud in Administration/Projects/HSE — while ownership is held by Franke Onsrud Invest AS. The business holds Sentral godkjenning (Central Approval), Miljøfyrtårn environmental certification, and memberships in Oslo Kobber og Blikkenslagerlaug, VBL, NHO, Metallplan, and Startbank, supporting its qualifications for public tenders.

Broad incumbents

• BMI Group (Icopal): Large European roofing and building envelope manufacturer and installer. Competes broadly in the same roofing/waterproofing segment but as a multinational supplier rather than a local specialty contractor.
• Protan: Norwegian roofing membrane and building envelope manufacturer serving commercial and industrial projects. Adjacent in roofing scope where Franke Onsrud competes on metal roofing systems.
• Isola: Norwegian manufacturer of building envelope membranes and roofing systems. Overlaps in roofing and weatherproofing scope for the same Norwegian construction customers but operates as a product supplier rather than installer.

Others

• Skanska Norge: One of Franke Onsrud's largest general-contractor customers; not a direct competitor but a key buyer whose procurement decisions directly shape the order book for specialty metalwork subcontractors.
• Veidekke Entreprenør: Major Norwegian general contractor and a documented customer of Franke Onsrud. Functions as a buyer of specialty facade and roofing subcontractor services rather than a competitor in the niche.
