Behind every piece of hardware is a detailed production process designed to guarantee performance, strength, and beauty.
Here’s how high-quality door knobs and handles are made—and tested.
1. Metal Composition & Strength Testing
Each alloy is inspected for density and durability.
✔ Prevents bending
✔ Ensures long-term use
✔ Supports heavy doors
2. Finish Testing: Salt-Spray & Corrosion Resistance
Coatings must withstand humidity, heat, and cleaning products.
3. Crystal & Glass Clarity Check
Only lead-free, optical-grade crystal is used.
✔ No bubbles
✔ No yellowing
✔ High clarity & shine
4. Mechanism Cycling Tests
Hardware is rotated and stressed thousands of times to simulate years of use.
5. Hand Inspection for Final Quality
Every item is checked before packaging.
