Powder Coating at Lehmann: Modern, Robust, and Full of Colour
Powder coating at Lehmann means meticulous work with state-of-the-art equipment. Skilled operators manage the entire process to ensure every component is coated uniformly and reliably protected.
What is powder coating?
Powder coating is a modern finishing process in which metal surfaces are treated without solvents. A fine powder is applied electrostatically to the prepared substrate and then cured at high temperatures. The result is a uniform, highly durable surface.
Unlike solvent-based paints, powder coatings contain no volatile organic compounds — a clear advantage for both the environment and workplace safety.
Our capacity and technology
Lehmann operates a powder coating system capable of processing components up to 3.00 m × 1.20 m × 2.00 m (L × W × H), making it possible to coat even large-format elements consistently and reliably.
The process demands careful pre-treatment. Only a clean, degreased, and in many cases chemically pre-treated substrate will accept the powder uniformly and guarantee adhesion for years to come.
Why powder coating?
- Solvent-free and environmentally friendly: no volatile organic solvents
- Uniform, pore-free surface with no runs or drips
- High impact, scratch, and abrasion resistance — robust even in demanding applications
- Weather and UV resistance — ideal for external use
- Extensive colour range: virtually all RAL and special colours available, in matt, gloss, or textured finishes
- Efficient material use, minimal waste — close to 100% material utilisation is achievable
- Ideal in the duplex system with galvanizing: zinc as the primary corrosion barrier, powder as the decorative and additional protective layer
Powder-coated components are found across many industries:
- Roofing and building products: roof systems, mounting systems, safety components
- Energy infrastructure: brackets, frames, fastening systems
- Facades and architecture: profiles, visible surfaces, railings
- Mechanical engineering and enclosures: functional components, covers
- Photovoltaics: mounting systems and components for outdoor use
Each application has its own specific requirements — whether chemical resistance, thermal stability, optical consistency, or coating thickness — all of which are taken into account at Lehmann.
Quality and control
With powder coating as with all its processes, Lehmann places the highest value on in-house quality assurance. Established test methods include cross-cut testing and dry film thickness measurement.
Particular attention is paid to the curing process: temperature, duration, and post-treatment must be precisely controlled to ensure the powder fully crosslinks and stabilises.
Because Lehmann often offers powder coating and galvanizing under one roof, transport between the two processes is minimised and both can be perfectly coordinated.
Where we are headed
Lehmann plans to make quality more visible — through digital inspection processes, visualisations from the production floor, or live insights into testing procedures. Customers should be able to see not only the result, but also understand the process behind it. There is further potential in combining powder coating with sustainability — for example through environmental EPDs or improved recyclability of surplus powder.
Powder coating is a process that protects, shapes, and delivers lasting value. Those who invest in metal today expect both aesthetics and durability — and that is exactly what Lehmann delivers.
