Architectural products made of stainless steel - 100% Made in Germany.
PHOS Design specialises in architectural products made of stainless steel. Our roots lie in architecture - we use this expertise to design and manufacture durable solutions for interior design in our factory in the Rhine harbour in Karlsruhe: sophisticated function, clear form and precise craftsmanship.
2nd place in the Handelsblatt ranking "Best Training Companies 2026" in the category of companies with fewer than 100 employees.
PHOS is present in specialist media and represented on industry portals – visible wherever architecture and design take place.
PHOS Design stands for stainless steel products with responsibility. As a regional company, we develop and manufacture long-lasting architectural products: with a focus on quality, design and social impact.
Our actions are characterised by a holistic understanding: we produce with green electricity, use regional networks and ship climate-neutrally. Stainless steel as a material is fully recyclable and part of a closed material cycle. We also offer a lifetime repair service and provide a 10-year manufacturer's warranty - for use over generations.
