detail

A single concealed door hinge boasts a load-bearing capacity of up to 40kg, a specification that enables it to effortlessly accommodate the various heavy door types commonly found in commercial buildings. Whether fitted to substantial solid wood office doors or metal shopfronts in retail premises, these hinges deliver exceptional load-bearing performance. They ensure doors operate smoothly during opening and closing, effectively preventing sagging or wobbling caused by insufficient support. This provides reliable assurance for the uninterrupted operation of commercial spaces.

Features

1.Exceptional Durability: The product has passed 200,000 cycles of testing under BS EN1935 standards. This rigorous testing simulates the diverse operational conditions encountered by door hinges during prolonged, frequent use. After enduring such high-intensity cyclic stress, the hinge maintains excellent mechanical properties and structural integrity. This translates to an exceptionally long service life in practical applications, significantly reducing replacement frequency and lowering long-term maintenance costs for commercial buildings.

2. Outstanding Fire Resistance: Certified to EN1634 fire standards, achieving a fire resistance rating of 132 minutes. Fire safety is a critical consideration in commercial buildings. This concealed door hinge effectively prevents fire spread through door gaps during a fire, buying valuable time for evacuation and firefighting operations. It substantially enhances the building's overall fire safety, fully meeting the stringent fire regulations for commercial structures.

3. Outstanding Corrosion Resistance: Demonstrated exceptional anti-corrosion performance through a 48-hour corrosion test per EN1670 standards. Commercial buildings operate in complex environments, potentially exposed to humidity, chemical erosion, and other adverse factors. This hinge maintains structural integrity and reliable performance in such harsh conditions, resisting rust and corrosion to ensure long-term quality and aesthetic appeal.

Beyond its robust performance advantages, this door hinge features an invisible design. Once installed, the hinge is concealed between the door leaf and frame, rendering it virtually invisible from the exterior. This creates a cleaner, more streamlined silhouette for the door, seamlessly integrating with diverse commercial architectural styles to enhance the overall aesthetic and quality of the space. Furthermore, the concealed design eliminates potential safety hazards associated with traditional exposed hinges, such as scratches or collisions, ensuring greater peace of mind during use.
