Australian Style Nylon Sliding Window Lock with Zinc Alloy Latch Cylinder

Product Specification

Australian-Style Nylon Window Lock

This nylon window lock is specifically designed for Australian-style sliding windows. The lock housing is made of nylon and features a zinc alloy latch and lock cylinder. The handle and lock body are integrated into a single unit, making it compatible with aluminum alloy and PVC-U sliding door and window profiles. The product complies with the QB/T 5338-2018 standard for door and window hardware. It withstands extreme temperatures, resists moisture, and prevents rust, making it a mainstream locking component for Australian-style sliding doors and windows.

Nylon + Zinc Alloy Composite Material: Combining Strength and Flexibility for Durability

The main body of the lock housing is made of high-strength nylon through one-piece injection molding, offering high toughness, impact resistance, and resistance to breakage, with a warm, non-chilly feel to the touch. Core load-bearing components, such as the latch and lock cylinder, are die-cast from zinc alloy, providing high strength and resistance to bending and breakage.

Surface colors include black, white, and silver, and surface finishes can be customized to meet customer requirements. The product has passed a 500-hour neutral salt spray test, demonstrating excellent rust and corrosion resistance. It operates reliably in environments ranging from -20°C to 60°C with humidity levels between 10% and 90%, making it suitable for both humid balconies in southern regions and outdoor settings in cold northern climates.

Key-operated locking mechanism with 350 N high-strength latch protection

Two dedicated keys are included as standard. The lock cylinder secures the latch to prevent doors and windows from being forced open, enhancing burglary protection for high-rise and street-facing openings. The latch has passed a 350 N tensile strength test; when locked, it engages firmly with the lock housing, ensuring it will not disengage during high winds or cause the door or window to rattle and let in drafts.

Integrated openwork handle design eliminates the need for additional handles. It offers a comfortable grip for pushing and pulling, with simple opening and closing operations that are easy for both the elderly and children to use; removable decorative covers conceal screw holes, ensuring a clean and attractive appearance.

Wide Profile Compatibility and Easy Installation

Compatible with the two major window and door profile materials—aluminum alloy and PVC-U—it is suitable for applications such as balcony sliding doors, interior partition sliding doors, and commercial sliding windows, facilitating bulk assembly by window and door manufacturers and saving time and effort.

Rigorous Performance Testing Ensures Long-Term Stability and Reliability

1. 100,000-cycle fatigue test: The latch and lock cylinder undergo 100,000 cycles of operation, ensuring smooth operation without jamming or loosening;

2. Complies with the QB/T 5338-2018 industry standard: Meets all requirements for mechanical properties, corrosion resistance, durability, and other metrics, ensuring worry-free acceptance for international trade projects;

With a lightweight overall structure and simple installation, it combines aesthetics, safety, and weather resistance, making it the preferred locking solution for manufacturers of sliding doors and windows both for export to Australia and for the domestic market.
