Galva Power Group

What Galva Power Group does

Galva Power Group operates Europe's largest hot-dip galvanizing service network under the ZINQ brand, headquartered in Gelsenkirchen, Germany, with origins dating to 1889 (originally Voigt & Schweitzer). The group runs more than 50 galvanizing and coating sites across Germany, France, Belgium, the Netherlands, and Poland, serving more than 25,000 customers that span industrial steel processors and fabricators, construction and infrastructure firms, metalworking artisans and SMBs, solar/renewable energy mount-structure fabricators, and private individuals. The holding structure consolidates several regional subsidiaries, including COATINQ (powder coating), Zincoat in the Netherlands, and Metalcynk and Ocynkownia Pokój in Poland, with ZINQ GmbH & Co. KG as the principal German operating entity (HRA 1688, Amtsgericht Gelsenkirchen) and Lars Baumgürtel, Norbert Thanscheidt, and Dr. Birgitt Bendiek as managing directors.

The core technology is batch hot-dip galvanizing (Stückverzinken) combined with powder coating, delivered through five proprietary branded surface systems: duroZINQ, microZINQ (claimed up to 80% zinc savings), colorZINQ, verticalZINQ, and ecoZINQ. ZINQ controls its own alloy chemistry via "Alloy on demand" and is the only provider of Cradle to Cradle Certified batch hot-dip galvanizing surfaces. Process development, automation, and robotics are concentrated in the 1,300m² ZINQ Futurium R&D center opened in 2021, supported by a ZINQ-4.0 MES/ERP production stack and a ReZINQ circular-economy take-back system for galvanized steel.

The revenue model is transaction-based industrial services: customers pay per tonne or kilogram of galvanized steel weight for galvanizing, per surface area for powder coating, and hourly rates from EUR 35/hour for add-on services. Revenue is not publicly disclosed. Customers are acquired through a distributed regional network rather than a centralized sales motion, and the company's growth levers are geographic expansion (notably via M&A into Central Europe), product-line extension (engineered coatings, low-carbon offerings), and sustainability-led differentiation under the Low Carbon ZINQ program and Cradle to Cradle positioning.

Core offering

Galva Power Group, operating under the ZINQ brand, is Europe's largest hot-dip galvanizing service provider, offering corrosion protection and powder coating for steel components across 50+ production sites in Germany, France, Belgium, the Netherlands, and Poland. The company serves industrial steel processors, construction, metalworking artisans, and renewable energy customers with branded surface systems (duroZINQ, microZINQ, colorZINQ, verticalZINQ, ecoZINQ), supplementary ZINQ 360 services, and a circular economy take-back program (ReZINQ).

Product overview

ZINQ (operating under Galva Power Group) is a European surface treatment company specializing in hot-dip galvanizing and powder coating of steel, founded in 1889. The core product portfolio centers on five brand surface families: duroZINQ® (standard hot-dip galvanizing with Cradle to Cradle® certification), microZINQ® (thin-layer zinc-aluminum alloy galvanizing using up to 80% less zinc), colorZINQ® (powder coating applied over or independently on steel for color and design), verticalZINQ® (vertical tube/profile galvanizing in a 7.5 m deep bath), and ecoZINQ® (sustainable Cradle to Cradle® certified variant). These core brands are supplemented by ZINQ 360 — a suite of add-on products and services including ZINQ® fix (repair), ZINQ® free (zinc-free surfaces), duroseal/duropass (post-treatment sealants), and ZINQ® tags (laser-marked component identification tags with MES/ERP traceability). The ZINQ Futurium R&D platform underpins innovation with alloy-on-demand development and automation capabilities. ZINQ's circular business model, Planet ZINQ®, integrates ReZINQ (take-back/recycling) and Low Carbon ZINQ (decarbonization) programs alongside its surface treatment operations across more than 50 European sites.
