Our four core systems—tilt-and-turn, casement, integrated-screen, and swing door—can be customized with various opening angles (90°/180°), load capacity ratings, 3D adjustment ranges, anti-error features, fall-prevention mechanisms, and multi-point locking configurations.
For heavy-duty sashes or narrow-profile systems, we tailor hinge load ratings and hardware groove dimensions for a precise fit with your specific window and door profiles.
We offer adjustable drive bar lengths and locking point layouts to accommodate specialized configurations, including wide sashes, tall sashes, and heavy-duty window and door types.
Our portfolio encompasses tilt-and-turn, casement, screen-integrated, and swing door systems with complementary accessories, providing one-stop, bundled customization solutions for dealers, fabricators, and system brands.
15 specialized laboratories span the full inspection chain—from incoming materials and in-process monitoring to final shipment—ensuring product reliability and consistent, high-quality output.
Backed by a 38,000 m² manufacturing base and lean production management, we combine efficient standard-product delivery with the agility to meet OEM/ODM and project-specific customization demands.
Our 100-person R&D center continuously advances the structure, performance, and application scope of window and door hardware systems. With over 100 certifications in innovative design and proprietary technologies, we bring solid technical expertise to every custom solution.
