About KFB Surfaces
KFB Holding GmbH (KFB Surfaces) is a corporate group specialized in surface technology, headquartered in Linz (Austria) with its core German site in Obernzell. The parent plant Herbert Bauer was founded in 1950 and processes up to 400 tons of material per day at the Obernzell site with around 400 employees. The group offers contract electroplating (electrolytic zinc plating acid and alkaline, zinc nickel, zinc iron, nickel plating, tin plating, silver plating, copper plating, chromium plating, electropolishing), coatings (KTL, powder coating, wet paint, Geomet zinc flake, electroless nickel, phosphating), pre- and post-treatments as well as mechanical manufacturing with laser cutting, CNC bending, robotic welding, 5-axis milling, tube bending, hydraulics fabrication and assembly. Materials processed include steel, stainless steel, aluminium, copper, brass and cast iron for industries such as automotive, commercial vehicles, mechanical engineering, agricultural machinery, electrical, furniture and construction industries as well as plant engineering. The group comprises eleven locations in Germany, Austria and the Czech Republic (SAK spol. s.r.o., Vimperk, over 4,000 m² of production space).
