RUD stainless steel chains
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.
Special features of the RUD stainless steel chains:
- resistant to rust and acid
- from 4 mm to 16 mm chain diameter
- similar to DIN 5684 part 1
- grade P: RPA and grade S: RSA
- without heat treatment
