Zinc Alloy Double-Sided Handle for Single-Leaf Swing Doors
This set of double-sided handles is specifically designed for single-leaf swing doors. Featuring a symmetrical, curved handle design on both the interior and exterior, paired with a through-type square shaft drive mechanism, it is compatible with aluminum and PVC-U door panels. Compliant with the QB/T 5338-2018 standard for door and window hardware, it has passed rigorous testing including 100,000 opening/closing cycles and 500 hours of salt spray testing, making it the top choice for bulk supply in residential and commercial swing door projects.
Composite metal construction ensures durability, weather resistance, and corrosion resistance.
The main base is die-cast from zinc alloy, providing resistance to prying and compression, and is unlikely to crack or deform under stress; the curved handle is made of aluminum alloy, offering a lightweight and smooth grip. Surface treatment processes can be customized as needed, with options including sandblasting, fluorocarbon coating, and anodizing. A wide range of color options—including silver, black, white, and champagne—is available to complement various door and window design styles.
Having passed a 500-hour neutral salt spray test, it offers excellent moisture and rust resistance. Even when exposed to prolonged sun and rain on balconies or street-facing exterior doors and windows, it is unlikely to rust, lose paint, or become jammed, ensuring stable performance in environments with temperature fluctuations and high humidity.
The dual-sided through-design ensures convenient opening and closing.
A through-type square shaft connects the inner and outer handles, enabling synchronized operation between the interior and exterior, allowing the door to be easily opened and closed from either side. The smooth, curved handle fits comfortably in the palm, requiring minimal effort to turn, and features no sharp edges to prevent bumps or scratches.
The base features multiple sets of standard mounting holes, compatible with common square-shaft specifications on the market. No additional profile modifications are required, allowing door and window manufacturers to assemble and commission the product simply and efficiently, significantly reducing assembly time. The internal transmission mechanism provides uniform damping; even after 10,000 twists, there is no sticking or abnormal noise, and it remains free of looseness or play even with long-term use.
Compatible with mainstream profiles, suitable for single-leaf swing doors
Compatible with the two major door and window profiles—aluminum alloy and PVC-U—it suits various types of interior and balcony single-leaf swing doors. It can be paired with matching lock cases and multi-point locking systems to form a complete door and window hardware system, suitable for residential, commercial, and office partition doors.
Highly Versatile Overall Structure with Standardized Cutout Dimensions: No need to create new molds to adapt to specific profiles; offers high compatibility for bulk purchases by hardware wholesalers and door/window manufacturers.
Multiple Durability Tests Ensure Consistent, Compliant Quality
1. 100,000-cycle opening and closing test: After prolonged, high-frequency twisting, the pivot shaft remains secure and the handle retains its shape, meeting long-term usage requirements;
2. Complies with the QB/T 5338-2018 industry standard: All performance indicators meet requirements, ensuring worry-free project acceptance;
The entire set of handles is solidly crafted and durable. Each unit undergoes multiple quality inspections for wear resistance, corrosion resistance, and torsional fatigue before leaving the factory, ensuring stability and reliability for long-term use in both residential and commercial projects.
