What Voigt & Schweitzer GmbH & Co. KG does

Voigt & Schweitzer GmbH & Co. KG, operating under the ZINQ brand, is a family-owned German industrial services group founded in 1889 and headquartered in Gelsenkirchen. The company specializes in hot-dip galvanizing (Feuerverzinken) and powder coating of steel components for corrosion protection, serving industrial customers in the steel construction, fabrication, infrastructure, and broader construction sectors. With approximately 1,800–2,000 employees and 50+ production locations across Germany, Belgium, the Netherlands, France, and Poland, ZINQ positions itself as the European leader in hot-dip galvanizing.

The technical core is hot-dip galvanizing, packaged into four proprietary branded offerings: duroZINQ (standard hot-dip galvanizing for lifetime corrosion protection), microZINQ (thin-layer galvanizing optimized for raw material efficiency), colorZINQ (galvanizing combined with color powder coating for aesthetics and protection), and verticalZINQ (vertical immersion galvanizing for tubes and profiles). The portfolio is extended through the COATINQ surface technology sub-brand and Zincoat powder coating operations in the Netherlands. R&D is concentrated in the wholly-owned subsidiary ZINQ Technologie GmbH, and the firm maintains additional wholly-owned operating entities including Galva Power Group NV (Belgium), Metalcynk and Ocynkownia Pokój (Poland).

ZINQ generates revenue through a transaction-fee B2B service model, with quote-based pricing dependent on steel volume, component dimensions, and treatment specifications. Distribution is exclusively direct: company-owned ZINQ service centers (notably Gelsenkirchen, Essen, Duisburg) and field sales teams across the European footprint, with no third-party resellers. The business is wholly controlled by sole managing shareholder Lars Baumgürtel (in place since 2008), alongside a multi-country executive team led by CEO Baumgürtel, CFO Bart Van Samang, COO Stéphane Vlahovic, and country-level MDs. No external institutional or private equity ownership is indicated, and revenue is not publicly disclosed.
