Why Choose Us？

1. Superior Material Engineering

Unlike cheaper aluminum alternatives, Degol uses high - grade zinc alloy.

Weight & Feel: Zinc alloy is denser, giving the handle a "heavy - duty" feel that consumers associate with luxury and security.

Precision Casting: The material allows for the smooth, ergonomic curves seen in your photo, ensuring a comfortable grip without sharp edges.

2. High - Traffic Durability

Degol's hardware is designed to exceed residential standards:

Cycle Testing: Their sets are typically tested for up to 200,000 cycles, meaning they can withstand years of frequent opening and closing in busy households or offices.

Mute Mechanism: They feature a "silent lock body" design where the latch is engineered to reduce noise, making it ideal for bedrooms and quiet office environments.

3. Advanced Surface Protection

The "Satin Nickel" or "Brushed Silver" finish on Degol sets is applied using advanced electroplating:

Anti - Rust & Corrosion: The finish is specifically treated to resist humidity, preventing the "pitting" or oxidation common in bathroom environments.

Fingerprint Resistance: The brushed texture hides smudges and oil, maintaining a clean look even with constant use.

4. Commercial - Grade Quality at a Residential Price

While Degol serves the commercial OEM/ODM market, their privacy sets offer "pro - sumer" benefits:

3 - Year Guarantee: Most Degol products come with a 3 - year mechanical warranty, which is a strong selling point for your customers.

Universal Fit: They are designed to fit standard door thicknesses (35mm–50mm) and include adjustable latches (60/70mm backset), making them a "no - hassle" replacement for existing hardware.
