Dacromet vs Zinc vs Nickel Roller Chain

The sample differentiates the families by finish and intended environment, not by a universal salt-spray-hour claim.

Family	Sample application wording	Available construction note
DR	Dacromet-plated chains are suitable for corrosive conditions	Duplex, triplex and double-pitch options
ZP	Corrosion-resistant zinc-plated chains	Duplex, triplex and double-pitch options
NP	Nickel-plated chains are suitable for outdoor conditions such as exposure to rain	Duplex, triplex and double-pitch options

Choose the final coating system through the project drawing and chemical declaration. A finish name alone does not define lubricant, corrosion-test method, acceptance criterion or service life.

Customer Reviews & Case Studies
