RUD Stainless steel chains for the food industry
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 motor-driven hoists. All rust and acid-resistant chains are designed and produced according to DIN 5684 part 1 and part 2.
Advantages of-the stainless steel chain for food industry
advantages of round steel chains compared to competitor systems:
- high resistance to wear
- high strength, optimal heat treatment
- precise calibration
- robust and durable
- low-maintenance compared to other systems
- less susceptible to corrosion due to the zinc flake coating
