Zinc Alloy Double-Sided Handle with Square Shaft
This through-type double-sided handle is specifically designed for double-leaf swing doors. It features an integrated full-length square shaft that enables simultaneous operation from both the inside and outside. The zinc alloy base is paired with an aluminum alloy curved handle, making it compatible with aluminum profiles and PVC-U profile door panels. It complies with the QB/T 5338-2018 industry standard for door and window hardware and has passed dual rigorous tests—100,000 opening/closing cycles and 500 hours of salt spray testing—making it the top choice for bulk supply of double-leaf doors in both residential and commercial projects.
Composite metal monolithic structure, weather-resistant, sturdy, and durable
The base is made of thickened die-cast zinc alloy, offering resistance to prying and compression, and remaining crack- and deformation-free even under long-term stress; the sleek, curved handle is crafted from aluminum alloy, providing a light and smooth grip. Its ergonomic curvature conforms to the palm, allowing for effortless twisting without any sharp edges that might cause discomfort.
Surface finishes support customer customization, including fluorocarbon coating, sandblasting, and anodizing. A wide range of color options—such as matte black, white, champagne, and silver-gray—is available to complement minimalist, light luxury, and modern home decor styles. The product has passed a 500-hour neutral salt spray test, offering moisture resistance and UV protection. Even when exposed to prolonged sun and rain on balconies or street-facing exterior doors and windows, it is unlikely to rust, lose its paint finish, or experience transmission jamming.
Through-Square-Shaft Dual-Side Interlocking, Designed Specifically for Double Doors
Featuring a through-rod square-shaft structure, the interior and exterior handles operate in synchronized motion, allowing for smooth opening and closing of door panels from both inside and outside. It is compatible with master-and-slave double doors and double-leaf swing doors. The base includes multiple sets of standard positioning holes, accommodating commonly available square-shaft specifications on the market. This eliminates the need for re-molding of profiles, enabling door and window manufacturers to assemble and commission the product simply and efficiently, significantly reducing assembly time.
The internal drive shaft is precision-engineered for wear resistance, providing uniform and smooth damping. It withstands 100,000 cycles of repetitive twisting without jamming, play, or abnormal noise, ensuring a stable and consistent feel even during long-term, high-frequency use.
Compatible with all mainstream profiles and suitable for multiple door types
Compatible with the two major door and window profiles—aluminum alloy and PVC-U—it works with interior partition double doors, balcony and entryway double swing doors, and commercial double entrance doors. It can be paired with corresponding lock cases and multi-point locking systems to form a complete door and window hardware system. Standardized cutout dimensions ensure broad compatibility, making it highly suitable for bulk purchases by hardware wholesalers and door/window manufacturers without the need for additional material modifications during production.
Multiple Authoritative Tests, Suitable for Both Commercial and Residential Projects
1. 100,000-cycle fatigue test: The hinge pivot exhibits low wear and tear, ensuring no loosening or handle deformation even during long-term, high-frequency use;
