KALMETALL is a metallic material that is produced by applying hard build-up welding to sheet steel.
As a manufacturer, we can specifically control the properties of the hard overlay welding by changing the welding filler materials and adjusting them precisely to the needs of the application.

The plates manufactured by Kalenborn are characterized by excellent abrasion and impact resistance. As a rubber composite KALIMPACT, a high reduction of noise and vibration is possible. These properties open up a wide range of applications for KALMETALL in numerous industrial plants.

Typical applications are screw conveyors, fan housings, cyclones and classifiers, mixer liners, piping components, screens, troughs, and conveyor troughs.


  • Very high abrasion and impact resistance
  • Standard thickness of the base material from 5 mm
  • Format sizes up to 1900 mm x 3900 mm
  • Welding thickness 3 – 18 mm
  • Application temperature max. 750 °C
  • Very high thermal shock resistance
  • Depending on the alloy selectable
  • Complete lining systems made of overlay welded sheet metal for existing steel constructions
  • Installation by welding, with screws or bolts
  • Self-supporting constructions with hard overlay welding
  • Ready-to-install components specially tailored to customer requirements
  • Combinations of ceramic and metallic materials for wear-oriented design with high cost-effectiveness
  • The KALIMPACT rubber compound   also reduces noise and vibration
