A full finish range for metal components, from a single plant
Guoshuo plates hardware components across a full range of finishes: copper, nickel, chrome, red copper, antique copper, and black nickel (gun metal). That covers both decorative requirements and protective ones, and it means you can consolidate several finishes with one supplier instead of splitting a bill of materials across three shops.
With multiple automated plating lines and more than twenty years of team experience, we serve appliance and furniture hardware, automotive components, bath and lighting fittings, wire products, casters and wheels, locks and chains, and luggage hardware.
