Craftsmanship Essence | Surface Treatment Technologies Redefining Home Aesthetics

Handle Craftsmanship  

The Dual Evolution of Tactility and Durability  

As high-frequency contact components, handles must withstand the test of time while fulfilling the ultimate pursuit of texture and beauty. 3H Building Hardware redefines handle standards through five core surface treatment technologies: High-Crystal Fluorocarbon, Oxidized Engraving, Nano Coating, Electrolytic Oxidation, and Hard Alloy Oxidation.  

High-Crystal Fluorocarbon  

- Weather & Corrosion Resistance: Passes 1,000-hour neutral salt spray tests, simulating extreme environments. Resists acid rain for 40 years in industrial cities and 25+ years in coastal high-humidity, high-salt areas.  

- Ultra-Hard Protection: Surface hardness reaches 5H, immune to daily impacts.  

Oxidized Engraving  

- Visual Elegance: Micron-level 3D textures create refined metallic finishes under light, eliminating the "plastic" look of traditional coatings.  

- Exceptional Durability: Scratch-resistant, salt-spray-proof, and fade-free, ideal for humid or variable climates.  

Nano Coating  

- Silk-Like Touch: Smooth as satin—warm in winter, non-sticky in summer. Electrophoretic deep matte black complements modern minimalist or industrial styles.  

- Self-Cleaning: Repels water stains and grease; cleans effortlessly with a wipe.  

Electrolytic Oxidation  

- Corrosion Resistance: Dense oxide film blocks moisture, salt spray, and acids, perfect for harsh coastal environments.  

- Scratch-Proof Shine: Enhanced hardness maintains metallic luster long-term.  

Hard Alloy Oxidation  

- Self-Healing: Oxide film automatically repairs minor scratches via oxidation.  

- Ultra-Wear-Resistant: Dense oxide layer + self-repair extends lifespan.  

- Corrosion Defense: Shields against moisture and chemicals, reducing maintenance.  

Stainless Steel Hinges  

Precision Engineering, Unseen Yet Essential  

Hinges are the "joints" of doors and windows—their surface treatment dictates longevity and performance. 3H elevates stainless steel with aerospace-grade electrolytic coating and precision grinding.  

Aerospace-Grade Electrolytic Coating  

- 120-Hour Salt Spray Breakthrough: Standard 304 stainless steel may rust within 72–96 hours; 3H’s coating prevents rust for 120+ hours.  

- Extreme Corrosion Resistance: Ideal for coastal/polluted areas, doubling lifespan.  

- Silent Smoothness: Noiseless operation even after decades of use. 

When a window glides flawlessly after decades of storms, when a handle grows more lustrous with time—this is 3H’s craftsmanship. Every detail withstands scrutiny; every touch delivers delight.  

(Note: All technologies comply with international durability and safety standards.)  

Key Takeaways:  

✔ Luxury Meets Resilience: From silk-touch handles to self-healing alloys.  

✔ Science-Backed Protection: Salt-spray/acid-rain tests validate performance.  

✔ Timeless Design: Surfaces age gracefully, enhancing home aesthetics.  

Choose 3H—where innovation becomes heirloom quality.
