A special technology allows lending the stainless steel of the single-lever mixer Colan a strongly curving line despite the material’s hardness. The treatment of the surface harks back to the wire drawing technique and ensures a very indurate metallic texture. Since stainless steel has antioxidant properties, the surface need not be galvanised. Thus, the manufacturing process is comparatively eco-friendly. No patina forms on the easy-to-clean material.
