About Carsten Potrz Industrievertretungen
Carsten Potrz Industrievertretungen is a sole proprietorship based in Langenfeld (Rhineland), specialising in the sale of semi-finished products. The range includes non-ferrous metals such as aluminium, copper, brass, bronze and red brass, special metals such as titanium and silver steel, as well as steel, stainless steel and plastics. In addition to the pure procurement of stock material for short-term requirements and mill quantities for long-term projects, services relating to metal are offered: sheets and plates are sawn or cut on modern equipment into blanks, discs and rings, laminated on request and delivered as ready-to-install finished parts according to drawing – as individual or series parts. Heat treatments, surface coatings and storage services are also offered through experienced cooperation partners. Customers include the metal processing industry, mechanical engineering, toolmaking, the construction industry and the advertising industry (plastics). The company supports its customers from material selection through technical consultation to the delivery of machined components.
