Electrochemical finishing for stainless steel, uniform and stress free
Short Answer
Guoshuo provides stainless steel electropolishing and passivation for foodservice, hardware and decorative parts. The stainless grade, weld condition, initial surface, geometry and finish target are reviewed before the process route is confirmed.
Guoshuo provides stainless steel electropolishing and electrolytic passivation. Electropolishing is an electrochemical process that dissolves the microscopic peaks on a surface, essentially plating in reverse. The result is stainless steel that is brighter, more corrosion resistant, and easier to clean.
Compared with mechanical polishing, electropolishing treats exposed surfaces electrochemically and can reach geometry that is difficult to buff consistently. It is used on foodservice equipment, formed stainless hardware and decorative parts.

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.
Frequently Asked Questions
How is electropolishing different from mechanical polishing?
Electropolishing dissolves the surface electrochemically, so it is uniform, stress free, and reaches complex geometry. Mechanical polishing removes material physically and struggles to reach recesses evenly. The two are often combined: mechanical polishing to level the surface, electropolishing to finish it.
Does electropolishing improve corrosion resistance?
Yes. It removes surface defects and embedded contaminants and leaves a cleaner, more uniform passive layer, which measurably improves corrosion resistance.
Which stainless grades can you process?
Common stainless grades can be evaluated. We confirm the material record or incoming sample before committing to a process route because alloy and prior surface condition affect the result.

What to Send for a Plating Quote
Send your drawing or part photos, base material, part dimensions, required finish, sample quantity and expected production volume. Include coating thickness, appearance, corrosion-testing requirements and delivery schedule where specified. For food-contact parts, tell us the food type, contact temperature, cleaning conditions and target market so that the testing scope can be evaluated before quotation.
We currently offer conventional electrolytic nickel plating, decorative chrome plating, wire mesh plating and stainless steel electropolishing. We do not operate an electroless nickel / Ni-P line. Final process suitability is confirmed after reviewing the part and specifications.
