The Engineering of
Commercial Resilience

The Heavy Duty Commercial Multipoint Operation Handle Set is Luoqi Hardware's definitive response to the rigorous demands of large-scale facade envelopes. Specifically designed for high-span doors and oversized commercial casements, this handle set serves as the primary actuator for the Durable Door System, converting minimal manual torque into high-pressure compression across multiple locking points.

At the heart of the Multipoint Operation is a reinforced steel-core drive logic. Unlike standard Quality Door Fittings, our commercial series features a high-tensile 8mm spindle hub, precision-tempered to withstand the persistent mechanical stress of public sector deployments. This ensures that the Architectural System remains hermetically sealed against both environmental factors and unauthorized entry.

Integration with Steel Window Accessories is seamless, thanks to the handle's universal mounting matrix. The oversized lever geometry provides the necessary leverage to drive internal Strip Lock Systems through the resistance of heavy EPDM seals, a requirement for achieving the 2026 energy efficiency benchmarks in executive suites and high-rise developments.

Finishing is handled via a multi-stage electrochemical process, providing a surface hardness of HRC 55. This PVD coating is specifically calibrated for anti-abrasion and anti-microbial properties, making it the ideal Secure Access Control interface for hospitals, airports, and corporate headquarters where durability and hygiene are paramount.
