Hot-Dip Galvanizing at Lehmann: Lasting Protection, Lasting Responsibility
Inside the zinc kettle of one of Europe's most modern plants, components are fully immersed. The result is a uniform zinc coating that protects steel against corrosion for generations.
Steel needs protection from rust
Corrosion is not a peripheral concern — it is one of the greatest challenges in construction. Without effective protection, steel loses structural integrity surprisingly quickly. Hot-dip galvanizing offers a solution that has stood the test of decades and remains as relevant as ever: a metallic coating that protects components from every angle and preserves their value.
Hot-dip galvanizing to DIN EN ISO 1461 is a batch process in which fabricated parts are immersed in liquid zinc. This creates a zinc layer that bonds metallurgically with the steel, reaching all surfaces, edges, cavities, and hard-to-access areas. Unlike coatings or paints, there are no weak points. The protection remains effective even under mechanical stress.
State-of-the-art technology in Europe
At its Neutraubling site, Lehmann operates one of the most modern hot-dip galvanizing plants in Europe. At its heart is a zinc kettle measuring 7.00 m in length, 1.60 m in width, and 3.20 m in depth — large enough to handle even substantial components such as beams and frames. Around 60 employees work in the galvanizing department, ensuring consistently high quality through experience and precision.
The coatings produced achieve protection lifespans of up to 100 years, as documented in DIN EN ISO 14713. Hot-dip galvanizing is therefore not merely a technical process — it is a genuine long-term investment.
Advisory and service as part of the process
At Lehmann, the service does not end at the zinc kettle. Experienced galvanizing and corrosion protection engineers are involved from the planning stage — advising on design for galvanizing, material selection, and compliance with relevant standards, from DIN EN ISO 12944 to DIN EN 1090 and DASt Guideline 022.
After galvanizing, Lehmann handles order picking on request — item-by-item or by order. Every delivery is carefully assembled, packaged, and secured to VDI 2700 for transport, preventing damage and simplifying on-site logistics. A dedicated fleet of five articulated lorries and twice as many swap trailers ensures fast turnaround times and flexible deliveries across Germany, right to the construction site.
Simple assembly work on series components is also available. Trained staff take the load off customers and ensure that components are ready for use quickly and reliably.
Sustainability: corrosion protection is environmental protection
Hot-dip galvanizing protects not just components — it protects the environment. Every galvanized beam that lasts for decades saves resources, reduces waste, and cuts the energy needed for replacement and maintenance.
As the German Galvanizers Association shows, hot-dip galvanizing saves up to three times more energy and raw materials compared with coatings or paint. Zinc itself is 100% recyclable, integrating the process into closed material cycles.
Lehmann applies high standards in emissions control, water management, and energy efficiency — making a contribution to sustainability that extends well beyond its own production process.
Industry engagement
As a member of the German Galvanizers Association, Lehmann stays in close dialogue with the sector. Quality standards are continuously developed, research findings shared, and expertise around hot-dip galvanizing strengthened. For customers, this means benefiting not only from the latest technology, but from the collective knowledge of an entire industry.
