WUPARTS stainless steel door handle is a core component of the intelligent door control system developed specifically for high-end buildings and smart communities. It uses food-grade 304/316 stainless steel substrate (chromium Cr≥18%, molybdenum Mo≥2.5%), and through five-axis linkage CNC machining and PVD nano-coating technology, it achieves surface hardness HRC 58±2 and corrosion resistance level NSS 2000 hours, which exceeds the national standard performance. The product complies with the ISO 9001/GB 17565 dual certification system, and is suitable for residential, medical, commercial complex and other scenarios. In particular, it optimizes the anti-rust structure for high-humidity areas (such as coastal areas and underground spaces), and its 10-year maintenance-free life is verified by dynamic salt spray accelerated aging test.

Wuparts door handle products are based on 10 years of technical accumulation in the field of building hardware, building a “material-structure-function” trinity solution:
1. Material innovation
Selected 316 stainless steel substrate (Cr≥16.5%, Mo≥2.0%), internal stress is eliminated through solid solution annealing process, and PVD nano-coating technology is used to form a TiN/TiCN composite film layer with a thickness of 3-5μm on the surface, which increases the scratch resistance by 3 times and does not fade after long-term use.
2. Structural optimization
• Dynamic balance system: built-in double-bearing shaft structure, friction coefficient ≤0.12, ensuring smooth opening and closing without jamming
• Anti-pinch patent: the end of the handle adopts a gradual curvature design (R angle ≥3mm), passed the GB/T 1802-2000 flexibility test
• Modular components: the handle core and the decorative cover are separated, supporting quick disassembly and maintenance
3. Intelligent expansion
Pre-set M12 aviation interface, compatible with mainstream smart lock protocols (such as Zigbee 3.0, BLE 5.0), response time <0.5 seconds. Equipped with emergency power supply interface, 9V battery can keep the electronic lock working for 72 hours.
4. Application scenarios
• Commercial space: hospital operating room IP54 protection design, resistant to 84 disinfectant wipes
• High-end residential: bronze etched pattern model is suitable for European copper art doors to enhance the texture of space
• Industrial plant: extended (180mm) explosion-proof handle meets the requirements of 1 million times of opening and closing of fire doors
5. Quality assurance
Passed the A-level certification of China Building Materials Inspection and Certification Group (CTC) and provided a 5-year warranty. 28 storage centers have been set up across the country to support 48-hour emergency replacement service.
This product has been successfully applied to 300+ landmark projects such as Shanghai Tower and Peking Union Medical College Hospital, with an average annual shipment of more than 2 million pieces, saving users more than 10 million yuan in maintenance costs. It is the preferred solution for building hardware upgrades.
