Zinc Alloy Square-Shank Door and Window Handles
This square-handle door and window handle features a minimalist, straight-edged design. It consists of a zinc alloy base paired with an aluminum alloy grip, compatible with profiles ranging from 30 to 120 mm in width. It complies with the QB/T5338-2018 industry standard and has passed dual rigorous tests: 100,000 opening and closing cycles and 500 hours of salt spray testing. It is suitable for various types of casement windows made of PVC or aluminum alloy and is widely used in residential renovation projects.
Composite Metal Construction for Sturdiness and Tensile Strength
The base is die-cast from zinc alloy, offering high strength and resistance to prying and compression; the square handle is made of aluminum alloy, providing a lightweight grip that resists bending. The entire hardware set passes a locking latch tensile strength test of up to 350 Nm, ensuring a secure lock engagement that prevents unlocking or door sagging even in high-wind conditions.
Surface finishes can be customized to meet customer needs, with options including fluorocarbon coating, anodizing, and sandblasting. These finishes complement a wide range of door and window colors—such as black, white, gray, and champagne—and suit modern minimalist and light luxury interior design styles.
Square, Ergonomic Handle: Intuitive Operation and Durability
The straight, square handle features clean lines and a grip that fits comfortably in the palm. The twist mechanism requires minimal effort and is gentle on the hands, with no sharp edges to prevent bumps or scratches. The base includes multiple adjustment holes to accommodate different profile cutouts, allowing for minor fine-tuning of the installation position. It is compatible with profiles ranging from 30 to 120 mm in thickness, offering a wider range of compatibility.
The internal transmission mechanism is precise and smooth, operating without jamming or unusual noises even after 10,000 cycles, and remains secure even with long-term, high-frequency use.
Compatible with All Types of Profiles for Quick and Efficient Installation
Compatible with both PVC and aluminum alloy profiles, covering various types of casement windows, including inward-opening and inward-tilting, as well as outward-opening and outward-tilting models. The base’s standardized multi-hole design simplifies on-site assembly for door and window manufacturers, eliminating the need for complex modifications and significantly reducing assembly time.
It can be paired with a drive box, sliding hinges, and multi-point locks to form a complete door and window hardware system, suitable for bulk installation in residential homes, retail spaces, and office buildings.
Multiple Rigorous Tests Ensure Suitability for Long-Term Outdoor Use
1. 100,000-cycle fatigue test: Repeated opening and closing without breakage or loosening of the hinges, meeting the demands of long-term, high-frequency use;
2. 500-hour neutral salt spray test: Excellent rust and corrosion resistance ensures that the hardware remains rust-free and operates smoothly even when exposed to prolonged sun and rain on balconies or outdoors;
Highly adaptable to various environments, it operates reliably in conditions ranging from extreme temperature fluctuations to high humidity. Manufactured in strict compliance with the QB/T5338-2018 standard for door and window hardware, the product ensures consistent quality and reliability, guaranteeing long-term performance for the doors and windows it equips.
