Mannen van Staal

What Mannen van Staal does

Mannen van Staal is a family-owned, full-service metal fabrication company headquartered in Leeuwarden, Friesland, the Netherlands, operating since its founding in 1985 (originally as Bakker Metaalbewerking in Winsum) and rebranded under its current name in 2010. The firm operates from a single site on Morseweg and runs an integrated production stack covering cutting (laser and tube laser), bending, certified welding (NEN 1090 EXC3), machining, and final assembly, enabling it to deliver complete subassemblies rather than piece-part work.

Its customer base spans industrial sectors (defense, utilities, infrastructure, healthcare, agriculture) alongside a distinctive art-installation practice developed through a long-running collaboration with Studio Ólafur Eliasson, with shipped projects including installations for Qatar Museums, Tate Modern, and venues in Hamburg and the United States. This dual positioning — industrial contract work plus high-tolerance design fabrication — is the defining feature of its commercial model.

The firm operates as a besloten vennootschap (Dutch private limited) with no external funding rounds disclosed; growth has been self-funded through retained earnings and family capital. Revenue mechanics are project-based: bespoke quotation, engineering, prototyping, fabrication, and on-site delivery, with contract values varying materially depending on whether the underlying job is industrial volume or premium art installation. The company has invested in operational sustainability — 3,000 solar panels and energy-neutral operations since around 2017, augmented by a 500 kWh MG Energy Systems battery in 2026 — and has begun commercializing solar carports as an adjacent offering. Headcount is approximately 16-25 employees.
