RUD chains for food

RUD offers the right chain for a wide range of applications. For applications with high demands on rust and acid resistance, RUD stainless steel chains offer a high degree of flexibility for manual and motorised hoists. All rust and acid-resistant chains are designed and produced in accordance with DIN 5684 Part 1 and Part 2.

Advantages of stainless steel chains for food

Advantages of round steel chains compared to competitor systems:

  • High wear resistance
  • High strength, optimally heat-treated
  • Precisely calibrated
  • Robust and durable
  • Low maintenance compared to other systems
  • Less susceptible to corrosion due to the zinc flake coating
