Surface Treatment: Multi-step finishing (including satin nickel) followed by 72-hour salt spray testing to validate corrosion resistance.
Lock Mechanism Integration: Privacy thumbturns are assembled and tested for 50,000+ cycles to ensure reliable operation.
Final QA Inspection: Each handle undergoes dimensional, functional, and visual checks—only 100% compliant units proceed to packaging.
