Overview
About J.D. Geck GmbH
Who we are
We manufacture your articles in the area of sheet metal processing and metal components Our extensive manufacturing capabilities cover the entire production process — from laser and punching of sheets, pipes and wire to automated production of welded components and surface finishing in our own electroplating and powder coating. We process carbon steel, stainless steel, aluminum, non-ferrous metals (copper/brass/bronze) and titanium. With continuous in-house production, we are able to produce reliably, independently and therefore efficiently. The production sites for this purpose are located in Altena (North Rhine-Westphalia) and Luckau (Brandenburg). As a German family company, we are your reliable supplier.
