Factory-direct engineered locking mechanisms customized for thermal break aluminum, vinyl (PVC), and wooden architectural window systems.
Vertical manufacturing integration, advanced alloy metallurgy, and zero-compromise security engineering designed for architectural scalability.
Unlike third-party hardware packagers, we melt, cast, die-cast, and machine our locking components in-house using virgin ZAMAK-3, ZAMAK-5 zinc alloys, and 304/316 stainless steel. No recycled scrap material is ever used.
Our multilayer surface treatments exceed EN 1670 Grade 5 corrosion standards, withstanding over 480 hours of neutral salt spray testing. Perfect for coastal buildings, high-humidity, and industrial envelope applications.
Engineered with interlocking mushroom cams and heavy-duty steel keep plates. Rigorously tested under EN 1627-1630 to defeat crowbars, manual forced entry, and static loads exceeding 6000N.
All safety restrictor locks and friction stays adhere strictly to BS EN 13126-5 rules, ensuring child safety compliance by limiting window opening clear distance to under 100mm under 250N forces.
We maintain an internal CNC mold shop capable of producing custom gearboxes, handles, espagnolettes, and strike plates within 15 business days from CAD design approval.
Every single batch undergoes automated cycle endurance testing up to 50,000 mechanical operations, backed by a comprehensive 10-Year Factory Warranty covering mechanical operation and coating integrity.
An executive guide for facade engineers, window manufacturers, and global hardware buyers evaluating structural integrity and compliance.

In modern architectural fenestration, window locks are no longer viewed merely as secondary mechanical latches. They serve as primary structural containment components responsible for structural wind-load resistance, acoustic seal compression, building envelope air tightness, and intruder prevention. The European CE mark indicates strict adherence to standard EN 13126 (Hardware for windows and door height windows), which governs mechanical testing parameters across 19 separate hardware categories including espagnolettes, friction stays, handles, and tilt-and-turn gearboxes.
For international procurement officers and facade consultants, verifying CE compliance requires auditing three core engineering metrics:
Multi-story residential buildings and educational infrastructure mandate strict child safety protocols. BS EN 13126-5 mandates that window restrictor locks limit the initial window opening distance to less than 100mm (3.9 inches). The restrictor mechanism must remain engaged under a minimum load of 250N and require a deliberate, dual-action key or release mechanism to disengage for emergency egress or maintenance. Our factory integrates concealed self-engaging child restrictors into casement, hopper, and tilt-and-turn systems, ensuring compliance with global building codes like California Title 24, UK Building Regulations Part O, and European Norms.
Strategic technological shifts reshaping hardware specifications for smart cities, net-zero buildings, and automated fenestration.
The traditional mechanical window handle is merging with building automation systems (BAS). Modern window lock manufacturing is shifting toward concealed electromechanical multi-point actuators powered by 24V DC brush motors. These systems automatically engage locks when smart thermostats register HVAC operation, or unlock for night-purge natural ventilation while maintaining security sensor reporting (Zigbee/Matter integration).
Global architectural specifications increasingly demand Environmental Product Declarations (EPD). Modern window lock factories must eliminate hexavalent chromium (Cr6+) plating and lead-alloy stabilizers. Procurement mandates are prioritizing 100% recyclable zinc alloys, lead-free brass, and eco-friendly trivalent chromium passivation techniques that reduce carbon footprints during electroplating.
As passive house insulation standards tighten (U-factors below 0.8 W/m²K), window locking mechanisms must apply uniform perimeter gasket compression. Next-generation lock hardware utilizes 3D adjustable linear drive gearboxes that pull sashes tightly against EPDM weatherstripping, eliminating air infiltration and thermal bridging around window perimeters.
From custom profile engineering to automated crate shipping, our structured factory protocol guarantees on-time project execution.
Our engineering team analyzes your window profile CAD files (Eurogroove, C-Groove, or Custom), sash dimensions, weight parameters, and required security grades (RC1 to RC3).
Using 5-axis CNC machining and 3D metal printing, we deliver working physical samples of custom gearboxes, handles, or stays for fit-and-function testing within 7 to 10 days.
Die-casting, robotic polishing, automated electroplating, and continuous assembly lines manufacture your order with high precision, maintaining tight tolerances down to ±0.05mm.
Finished window lock systems undergo final batch QC inspection, are anti-rust wrapped, master carton packed, palletized, and prepared for global sea freight container export.
Essential technical answers for hardware distributors, window factories, and architectural project specifiers.
Every shipment of our CE certified window locks is accompanied by official Certificates of Conformity (DoP - Declaration of Performance) issued by accredited European notified testing bodies. We supply comprehensive EN 13126 test reports detailing cycle durability, sash load capacities, and EN 1670 corrosion resistance test certificates for your project compliance documentation.
Yes. While our standard lock lines are designed for universal 16mm Eurogroove and standard C-groove profiles, our factory specializes in custom OEM/ODM hardware manufacturing. Send us your profile cross-section CAD drawings, and our tooling shop can design matching drive rods, lock keepers, and gearboxes tailored specifically to your extrusion system.
Our standard electroplated zinc finishes achieve EN 1670 Grade 4 (240 hours neutral salt spray), making them ideal for standard urban environments. For coastal, marine, or highly corrosive industrial zones, we offer premium PVD coatings, anodized aluminum finishes, and 316-grade stainless steel assemblies that surpass Grade 5 (480+ hours neutral salt spray testing) without surface pitting or red rust.
For standard catalog window lock items, our factory MOQ starts at 1,000 sets per item. For custom OEM finishes, private branding laser etching, or customized profile hardware tooling, the MOQ ranges between 3,000 to 5,000 sets depending on material specs. We offer sample kit orders for engineering validation prior to full commercial production contracts.
Our child safety window restrictor locks limit the sash opening angle to a maximum clear width of under 100mm. They feature automatic engagement upon window opening and require a dedicated key disengagement or dual-push safety release to fully open the sash. Designed to withstand dynamic impact forces exceeding 250N in compliance with BS EN 13126-5 standards.
Standard catalog items are produced and shipped within 15 to 20 calendar days. For custom OEM hardware requiring new die-casting molds or extrusion dies, tooling fabrication and sample approval require 15 to 20 days, followed by mass production delivery in 25 to 30 days depending on container volume.
Yes. Our tilt-and-turn multi-point lock systems feature integrated corner drives, anti-mishandling devices, and false-operation restrictors. The single handle operation controls bottom-hinged tilt ventilation mode as well as full side-hung casement swing mode with smooth mechanical transition.
