About us
Maschinenbau Kolbe GmbH manufactures welded fabrications and welded assemblies in steel and stainless steel for mechanical and plant engineering. At the Waldkirchen site in the Vogtland region, the value chain includes cutting on mitre band saws, plasma cutting, MAG/MIG, TIG and manual welding in separate steel and stainless steel production areas, as well as machining such as boring mill work, milling, turning and deep-hole drilling, partly in cooperation with economic partners. The range of services is rounded off by heat treatment (annealing), blasting and surface technology including wet painting, powder coating, hot-dip galvanizing and electro-galvanizing. Assemblies up to 15 m in length, 3.50 m in width, 2.80 m in height and approx. 5 t in weight are manufactured. The company works to DIN EN ISO 3834-2 and is certified to DIN EN 1090 EXC2; shipping is handled by its own in-house forwarding agent, nationally and internationally.
