This Australian-style D-handle lock is crafted from a composite of zinc alloy and aluminum alloy. Designed specifically for sliding doors in the Australian market, it integrates the handle and locking mechanism into a single unit, ensuring simple installation and convenient operation. It has passed all performance tests and complies with relevant standards, making it suitable for residential projects, commercial construction, and large-volume export orders.
Durable, Age-Resistant Materials with Rigorous Testing and Certification
The core structure of the lock body is die-cast from high-density zinc alloy and reinforced with aluminum alloy components. This design ensures high overall hardness and excellent resistance to external impacts and tensile deformation, preventing cracking or loosening even with long-term, high-frequency use.
The product strictly complies with the QB/T5338-2018 national standard for door and window hardware and has successfully passed a 100,000-cycle durability test, ensuring maximum stability during daily, long-term use. The latch has undergone tensile testing and can withstand forces exceeding 500 N, ensuring a secure lock that resists forced prying or pulling. Having passed a 500-hour salt spray corrosion resistance test, the product offers outstanding moisture and rust resistance, making it highly resistant to rust and corrosion even in humid, rainy balcony environments along the coast.
It operates within an ambient temperature range of -20°C to 60°C and an ambient humidity range of 10% to 90%, functioning normally in both high-temperature, direct sunlight and cold, damp environments. Standard surface finishes include black, white, and silver spray-painted options, and custom colors are available upon request to match various door and window color schemes.
