Reliable Railway Fire Door Solutions for Enhanced Safety
Custom rail-certified fire doors in subway/metro station intervals, technical precision and safety-critical value for rail transit authorities and contractors.At Longhui Sanhe, we specialize in Railway fire door solutions designed to protect trains, railway stations, and associated infrastructure. Our solutions combine advanced fire-rated technology with robust design, ensuring passenger safety and regulatory compliance across the rail industry.
① Critical Compartmentalization
Seal Safety, Section by Section: Custom Fire Barriers for Subway Tunnel Integrity.
Focus: Preventing smoke/fire spread between stations, platforms, and tunnels.
② High-Density Crowd Protection
Engineered for Evacuation Efficiency: Fire Doors That Keep Passenger Flow Moving, Even in Crisis.
Focus: 120-180 min fire ratings (exceeding EN 1363/BS 476), zero-obstruction sliding systems, and acoustic sealing (≥32 dB).
③ Extreme Environment Resilience
Built for the Underground: Corrosion-Resistant, Vibration-Proof & Low-Maintenance.
Focus: Stainless steel hardware, humidity-resistant seals, and EMC compliance (electromagnetic interference resistance).
At the heart of Every Safe Railway System Lies An Unseen Guardian: the certified fire door. Installing these critical barriers isn't just a technical task; it's a profound responsibility shouldered by our dedicated Railway Fire Door Installation Engineers. They understand the weight of their role: lives, infrastructure, and operational continuity depend on their precision and vigilance.
Engineered for the "Underground" Challenge
Railway infrastructure demands more than just fire resistance. LHSH doors are designed to handle:
Piston Effect Resilience: Our doors are tested to withstand recurring pressure cycles (±2500Pa) caused by high-speed trains passing through tunnels without structural fatigue.
Extreme Thermal Protection: Offering up to 180 minutes of fire integrity, specifically tested against the HCM (Modified Hydrocarbon) curve which simulates the rapid temperature rise of tunnel fires.
Smoke & Toxic Gas Seal: Integrated with advanced intumescent seals that meet EN 1634-3 standards, preventing the migration of life-threatening smoke between station sections.
