About Zaunrith
Zaunrith Fahrzeug- und Fertigungstechnik in Frankenburg am Hausruck (Upper Austria) is a family-owned company with around 35 employees on approximately 3,000 m² of production space, manufacturing components and assemblies for the metal industry, plant engineering and vehicle construction. Its core competencies are heavy steel construction and large-part machining – from the development of individual components through assemblies and small series to series production including final assembly and transport. Parts production uses oxy-fuel flame cutting (sheet thicknesses up to 300 mm), plasma cutting and a CNC-controlled 300-t press brake for parts up to 20 t; structural steels, stainless steels and aluminium are machined. A second pillar is vehicle technology with customised trailer and vehicle superstructures, for example for Effer cranes or wood chip transports, complemented by special surface treatment. The company is certified to ISO 9001, EN 1090-1 EXC3 and EN ISO 3834-2.
