Which type of cupboard lock is the strongest? – Korong, a well-known brand of electronic smart locks, provides a comprehensive analysis from the perspectives of materials, structure, and safety certifications.

In our daily lives, kitchen cupboard locks need to be not only sturdy and durable but also able to withstand the humid kitchen environment and frequent opening and closing. Therefore, a good kitchen cupboard lock is extremely important.

1. Material and Craftsmanship: 304 Stainless Steel and Thickened Zinc Alloy Design are the Mainstream

304 Stainless Steel: Double guarantee of corrosion resistance and impact resistance. In humid kitchen or bathroom environments, ordinary alloy locks are prone to structural loosening due to oxidation and rust. 304 stainless steel, with its excellent corrosion resistance, is the preferred choice for high-end cupboard locks.

Thickened Zinc Alloy Design: A cost-effective option. For users with limited budgets, zinc alloy material, through thickening treatment, can also achieve high-strength protection. Korong cupboard locks use solid zinc alloy thicker than 2mm, which can be locked by rotating 90°. Tests show it can withstand a pulling force of over 50kg without deformation.

2. Structural Design: Anti-pry lock cylinder and multiple protection mechanisms are key

Anti-pry lock cylinder: Blocking technical unlocking from the source. The lock cylinder is the core component of a cupboard lock. Korong cupboard lock cylinders, due to their complex blade structure, have become a benchmark for preventing technical unlocking. For different usage scenarios, cupboard locks need to have targeted protection designs. Korong adds electroplating and polishing surface treatment to its cupboard locks, which prevents rust and improves shear resistance.

3. Safety Certification: Double verification of international standards and actual test data

International Standards: Opening cycles and fire resistance tests. According to the European standard EN1154, cupboard locks must pass 500,000 opening tests to ensure long-term durability. Korong cupboard locks completed 600,000 opening and closing tests in a laboratory environment, and the lock body remained intact, far exceeding the standard requirements. In addition, fire resistance testing is also an important indicator. The EN1634 standard requires the lock to maintain its functionality for 30 minutes at 800℃, making it suitable for kitchens and other areas with fire risks.

In short, the sturdiness of a cupboard lock is not simply determined by the material, but rather a comprehensive reflection of materials, structure, and certification standards. Kerong cupboard locks are exported to mature markets such as Europe and the United States.
