Double-Sided Flat Door Handle Set (Single-Sided with Twist Lock)
This double-sided handle set is available in a lockable twist-style security version and a basic version without a twist lock. The inner and outer handles are designed as a matching pair, specifically for single-leaf swing doors. Featuring a zinc alloy base paired with a streamlined, curved aluminum alloy handle, it is compatible with aluminum alloy and PVC-U profile door panels. Compliant with general testing standards for door and window hardware, it offers weather resistance and durability, making it the top choice for bulk installation in both residential and commercial swing doors.
Integrally Molded Composite Metal for Long-Lasting Outdoor Corrosion Resistance
The load-bearing base is made of thickened die-cast zinc alloy, offering resistance to prying and compression, and remaining resistant to deformation or breakage even after prolonged use. The sleek, curved handle is crafted from aluminum alloy with an ergonomic design that fits the palm comfortably; it allows for effortless twisting and features no sharp edges to prevent bumps or scratches.
Surface finishes can be customized to include fluorocarbon coating, sandblasting, anodizing, and other processes, with a wide range of colors available, including dark brown, matte black, white, silver, and champagne. The product has passed a 500-hour neutral salt spray test, offering UV resistance, moisture resistance, and rust prevention. Even when exposed to prolonged sun and rain on balconies or street-facing doors, it resists fading, rusting, and mechanism jamming. The matching lock latch meets the 350 Nm torque standard, ensuring a tight, secure lock that resists unlocking and air leakage even in strong winds, thereby enhancing the door and window’s sealing and anti-theft performance.
Single-Side Twist with Dual-Side Interlock: A Safe and Flexible Dual-Option Design
1. Single-Side Twist Design: No lock on the exterior; the interior is equipped with a twist-lock switch, allowing the handle to be locked with a single button press from the inside, while preventing opening from the outside; Ideal for balcony doors and interior partition doors, this feature allows for interior deadbolting at home to prevent unauthorized entry while also preventing children from opening the door on their own to go outside.
2. Through-Square-Shaft Synchronized Linkage: The interior and exterior handles are connected via a through-rod square shaft, ensuring smooth, synchronized operation from both sides with a consistent feel; the side without the twist lock serves as the standard base model, meeting simple usage needs in low-risk areas.
The internal pivot shaft features a wear-resistant cushioning mechanism, ensuring 100,000 cycles of opening and closing without jamming or abnormal noises; it remains tight and free of play even with long-term, high-frequency use.
Compatible with standard profiles; simple installation and setup
Compatible with the two major door and window profiles—aluminum alloy and PVC-U—and suitable for standard single-leaf swing doors; the base features standard, universal mounting holes, compatible with commonly available square drive shafts on the market, and can be paired with matching lock cases and multi-point locking systems to form a complete door and window hardware system. Standardized cutouts eliminate the need for additional material modification or slotting, saving time and labor for door and window manufacturers during assembly and significantly reducing labor costs.
Rigorous Durability Testing Ensures Stable and Reliable Procurement for Construction Projects
1. 100,000-cycle fatigue testing: The pivot shaft and latch hook exhibit low wear and tear; even with long-term, frequent use, the handle remains secure and retains its shape;
2. The product complies with the QB/T 5338-2018 industry standard for door and window hardware, meeting all requirements for mechanical strength and corrosion resistance. It is suitable for bulk procurement to equip residential developments, commercial spaces, and international construction projects.
