About Stahl- und Metallbau Petzoldt
Stahl- und Metallbau Petzoldt GmbH is a metal processing company based in Bad Köstritz (Thuringia) with a focus on steel and metal construction, apparatus and plant engineering, and stainless steel processing. Its range of services covers steel and metal structures from heavy steel construction to light steel construction, sheet metal and welded constructions, steel built-in parts, tank and enclosure fabrication, silencers, welded assemblies, and industrial production of components and assemblies. Plant engineering is offered as a complete service – from design through manufacturing to delivery and installation. Production is carried out in steel and stainless steel, with stainless steel also pickled, passivated and polished; pickling, passivating and polishing are also part of the repertoire. Sheet metal fabrication uses NC and CNC technology, including a 7-axis press brake Novakraft PBH 3200x160t, the Trumpf TruPunch 1000 punching/nibbling machine, and a CNC-controlled roll bending machine; computer-controlled welding systems are used for complex welded constructions. Single-piece and series production as well as supply services are realized. The company is certified to EN 1090-2 EXC2 for welding of steel load-bearing structures and to DIN EN ISO 3834.
