RUD D-profile chains
RUD D-profile chain, the round steel chain 2.0, is the leading technologically advanced round steel chain. Thanks to a larger cross-sectional area, it has a higher maximum load capacity with hardly any change in dimensions and weights. RUD D-profile chains are case-hardened and designed for higher wear requirements.
