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 33 years of plating experience, we serve appliance and furniture hardware, automotive components, bath and lighting fittings, wire products, casters and wheels, locks and chains, and luggage hardware.

Quality & Testing
Salt spray testing and coating-thickness measurement can be arranged to agreed specifications. Existing food-contact reports apply only within the product and process scope stated in each report; they do not establish compliance for a different substrate, coating stack, production process or intended use. For other products, project-specific third-party testing and reports can be arranged according to customer and target-market requirements. RoHS and other material requirements are likewise confirmed against the applicable product and report scope.
