Advantages of Dorprime Fire Rated Doors
Engineered fire rated doors provide verified compartmentation against smoke and fire while ensuring seamless architectural integration into high-density developments.
Restricts Spread of Fire, Heat & Smoke
Fire doors form an impenetrable barrier that stops flames, lethal toxic gases, and radiant heat transfer between compartmentalized zones, minimizing property damage.
Ensures Safe Occupant Evacuation Time
Maintains full structural integrity under thermal loads exceeding 1000°C for up to 120 minutes, ensuring building occupants have clear, safe egress passageways.
Elevates Life-Safety & Regulatory Compliance
Fully complies with National Building Code (NBC 2016) and State Fire Service guidelines, making occupancy certification and statutory audits completely smooth.
Engineered High-Duty Durability
Constructed with 1.6mm corrosion-resistant galvanized iron, precision mig-welded internal stiffeners, and heavy-duty ball bearing hinges for decades of service.
Acoustic & Environmental Insulation
High-density mineral fiber cores dampen building noise transmission and prevent drafts, improving climate control and HVAC efficiency.
Certified National & International Standards
Manufactured strictly to IS 3614:2021 and BS 476 test standards, backed by computerized CNC fabrication and third-party laboratory test reports.
