Steelpaint GmbH has secured a series of new contracts to supply corrosion protection coatings for Germany’s inland waterways, reflecting increased demand from federal and regional authorities investing in hydraulic infrastructure renewal.
Among the latest projects is work by WSA Main on the Main River at Viereth-Trunstadt, part of a maintenance and renewal programme to extend the life of key hydraulic structures. The Main, a major tributary of the Rhine, forms one of Europe’s most important inland transport routes, linking the North Sea and the Black Sea via the Rhine-Main-Danube canal system.
Steelpaint’s polyurethane-based coating system – comprising Stelpant-PU-Zinc, Combi 300 and Stelcatec-L-TC, a UV-resistant topcoat – is being used to replace an ageing two-component epoxy coating from another manufacturer. Surface preparation and application work is being undertaken by Muehlhan Deutschland GmbH.
Applied in several layers to a total dry film thickness of around 580µm, the coating protects approximately 500m² of steel surface, offering long-term resistance to corrosion, abrasion and UV degradation.
Frank Müller, head of sales at Steelpaint, says the company is seeing continued growth in demand across Germany’s inland-waterway sector. “We are witnessing continued growth from Germany’s inland-waterway authorities, who increasingly recognise the durability, ease of application, logistical advantages and environmental benefits of our moisture-curing polyurethane coatings,” he says. “Projects such as Viereth-Trunstadt confirm Steelpaint’s position as a trusted supplier for critical public-sector infrastructure.”
Dmitry Gromilin, technical manager at Steelpaint, says the system offers practical advantages over conventional epoxy coatings. “When applied at the correct DFT, the combined benefits of Stelpant-PU-Zinc, Combi 300 and Stelcatec-L-TC provide the ideal solution for exposed weir and dam environments where moisture and drying time can be variable,” he says.

Steelpaint expects strong demand through 2026–2027, supported by ongoing public investment in weirs, locks and flood-control assets. Upcoming projects include the Oste barrage and Kriegenbrunn lock on the Main-Donau canal.
