I. Core Performance Parameters: Meeting the Rigorous Standards of Five-Star Hotels
1. 80KG Heavy-Duty Load Capacity:
A single hinge securely supports thickened fire doors, solid wood doors, or metal doors, accommodating heavy-duty door types such as hotel guest room doors, VIP suite doors, and fire escape doors. This fulfils the ultimate durability requirements for door control systems in premium hotels.
2. 180° Full Swing Design:
The door lies flush against the wall, freeing corridor space and eliminating the visual disruption of exposed traditional hinges. This is particularly suited to narrow hotel corridors or suite designs requiring maximum area utilisation.
3. 200,000-Cycle Durability Testing:
After 200,000 opening and closing tests according to BS EN1935 standard, the service life of the hotel room door can reach more than 10 years even if it is used frequently every day (such as room service and guest access), which significantly reduces the maintenance cost.
II. Safety Certifications: Fortifying Fire Defences for Five-Star Hotels
1. 132-Minute Fire Rating:
Complies with EN1634 standards, sustaining fire containment for 132 minutes under high temperatures. This provides critical evacuation time for hotel guests, meeting the most stringent fire safety requirements for premium establishments.
2. 48-Hour Corrosion Resistance:
Passed EN1670 salt spray testing. The silver-grey surface features a high-strength anti-corrosion coating, resisting corrosion in humid hotel environments (e.g., pool areas, spa zones) while maintaining structural integrity and a pristine appearance long-term.
3. Concealed anti-pry design:
Hidden installation minimises exposed components, reducing tampering risks. When paired with fire doors, it elevates the hotel's overall security level, safeguarding guests' privacy and property.
III. Materials and Craftsmanship: Silver-Grey Metallic Finish Embodies Luxury Aesthetics
1. Zinc Alloy Body + Aluminium Alloy Connectors:
The zinc alloy body delivers high strength and impact resistance, ensuring stable hinge load-bearing capacity. Aluminium alloy connectors offer lightweight durability, optimising door opening/closing smoothness while minimising noise.
2. Silver-grey matte surface finish:
The understated, luxurious silver-grey hue seamlessly integrates with modern minimalist, light luxury, or contemporary Chinese hotel interiors. The surface resists fingerprints and scratches, minimising visible dirt during daily use to maintain lasting cleanliness.
IV. Tailored Suitability for Five-Star Hotel Settings
1. Guest Room Doors: Prioritising Safety and Silence:
80kg load capacity accommodates reinforced soundproof fire doors, with 132-minute fire certification providing dual assurance for guests; silent buffer design minimises opening/closing noise to avoid disturbing distinguished guests' rest.
2. Fire Escape Doors: High-Frequency Use and Durability:
Withstands 200,000 cycles to meet the demands of frequent opening and closing in hotel fire escape routes. Fire-rated certification complies with fire safety regulations, ensuring unimpeded access during emergencies.
3. VIP Suites/Executive Lounges: Aesthetic and Functional Enhancement:
Invisible design conceals the door control system. The silver-grey surface complements premium decorative materials (such as marble and metal trim), elevating the overall spatial quality to create an exclusive and prestigious experience.
