High Quality Door Hinge Heavy Duty Invisible Hinge fire rated concealed hinge

A 180° fully concealed hinge engineered specifically for fire doors, featuring an 80kg load capacity, three internationally recognised certifications, and a silver-grey metallic finish. This solution delivers both safety performance and visual appeal for fire door systems in commercial buildings, public spaces, and high-end residences. Below is an in-depth analysis of the product's core value across performance, safety, materials, and design compatibility:

I. Exceptional Performance: 80KG Load Capacity Redefines Fire Door Control Standards

High Load Capacity: Each hinge reliably supports heavy doors up to 80KG, accommodating solid wood, steel, or composite fire doors. Effortlessly meets stringent load-bearing requirements for fire doors in commercial complexes, hospitals, schools, and similar settings.

180° Full-Flap Design: The door lies flush against the wall, eliminating the protrusion caused by traditional exposed hinges. This maximises passage space in narrow corridors and lift lobbies, optimising evacuation efficiency.

200,000-Cycle Durability Testing: Passed BS EN1935 standard testing for 200,000 opening/closing cycles. Maintains structural integrity even under high-frequency use (e.g., hundreds of daily operations in shopping centre fire exits), significantly reducing long-term maintenance costs.

II. Safety Certification: 132-Minute Fire Resistance, Establishing a Lifesaving Barrier

Fire Performance Benchmark: Complies with EN 1634 standard for 132-minute fire certification, continuously blocking fire propagation in high-temperature environments to secure critical evacuation time. Meets fire safety regulations for high-rise buildings, underground spaces, and similar venues.

Corrosion Resistance Assurance: Passes EN1670 standard 48-hour salt spray testing. The silver-grey surface features a high-strength anti-corrosion coating, resisting corrosion in humid environments (e.g., basements, pool areas) to ensure hinge functionality under extreme conditions.

Anti-pry concealed structure: Hidden installation minimises exposed components, reducing tampering risks. When paired with fire doors, it enhances overall security levels, safeguarding property and privacy.

III. Materials and Craftsmanship: Silver-grey metallic finish blending functionality with aesthetics

Zinc alloy body + aluminium alloy connecting strips:

The zinc alloy body delivers high strength and impact resistance, ensuring stable load-bearing capacity. Aluminium alloy connecting strips offer lightweight durability, optimising smooth door operation while minimising noise.

Silver-grey surface treatment:

Features a fingerprint-resistant, scratch-proof matt coating that resists soiling during daily use. Complements modern minimalist, industrial, or light luxury interior styles.

The understated silver-grey tone complements diverse interiors, creating visual contrast with fire doors' red warning labels to meet safety standards while seamlessly integrating into spatial design—avoiding the aesthetic clash often associated with safety fixtures.

IV. Application Scenarios: The Ideal Choice for Commercial and Residential Fire Doors

Commercial Buildings: Fire escape doors and equipment room doors in shopping centres, office towers, and hotels, maintaining safety and durability under high-frequency use.

Public Facilities: Fire compartment doors in schools, libraries, and sports halls. Concealed designs minimise spatial oppression, enhancing user experience.

Premium Residential: Apartment entrance fire doors and stairwell doors. 132-minute fire certification provides extended escape time, while the silver-grey finish complements contemporary home aesthetics.

V. Product Value Summary

Safety Assurance: Triple protection against fire, forced entry, and corrosion safeguards lives and property.

Durability: Withstands 200,000 cycles and 80kg load capacity, suitable for high-frequency use and heavy-duty installations.

Aesthetic Enhancement: Silver-grey concealed design elevates fire doors as a design asset rather than a compromise.
