About us
Maschinen- und Stahlbau Bergeler GmbH in Rostock fabricates metal constructions such as frames, racks, and special designs, performs machining on lathes, milling machines, and CNC machines, and specializes in welding work using TIG (141), MIG/MAG (135), and manual metal arc (111). A core competence lies in piping, vessel, and plant construction, including stations such as gas regulation, gas mixing, and metering modules for various pressure levels and media, as well as module and pressure vessel manufacturing. In stainless steel processing, glass bead blasting is used, producing matte or silk-glossy, more corrosion-resistant surfaces. The offering is rounded out by assembly work and engineering services. Processing is performed mainly from steel and stainless steel for industry, pressure equipment technology, gas and oil technology, water treatment, and plant engineering. The company operates according to a certified quality management system under DIN EN ISO 9001:2015.
