Fire-Resistant Cast Aluminum Double Swing Door

Hongfeng’s factory-designed Fire-Resistant Cast Aluminum Double Swing Door is built around a core flame-retardant structure. It uses high-purity flame-retardant cast aluminum substrates and special fireproof filling materials, treated with high-temperature curing technology to endow the door with inherent non-combustible and non-melting properties. Equipped with multi-stage fireproof sealing strips and thermal break insulation technology, it resists fire intrusion and effectively blocks high-temperature conduction. With the grand layout of a double swing door and exquisite craftsmanship, it serves as a safe, reliable and high-quality guardian for any space.

Product Features

1.Fire-Resistant Structure: The Fire-Resistant Cast Aluminum Double Swing Door adopts an integrally molded high-strength flame-retardant cast aluminum frame with a dense, seamless structure. It has passed national professional fire resistance testing and certification, and can fully withstand flames, smoke and high temperatures within the specified time.

2.Flame Retardancy & Heat Insulation: Built with professional fireproof and heat-insulating core materials and a high-temperature resistant sealing layer, it effectively isolates thermal radiation and conduction, lowers door surface temperature, protects personnel safety and indoor property, and extends escape time.

3.Stability & Durability: Cast aluminum material is inherently high-temperature resistant, corrosion-proof and non-combustible. Paired with heavy-duty hardware specially designed for double swing doors, the door structure is firm, wind-pressure resistant and deformation-proof, maintaining stable performance in various environments for a long time.

Fire Safety System

1.Full-Chain Fire Protection: A triple fire defense system is formed combining non-combustible substrates, fireproof filling layers and sealed heat insulation, covering everything from the door structure to gap sealing, with a fire rating far exceeding ordinary doors and windows.

2.Dynamic Smoke Blocking: The exclusive fireproof sealing strips expand when exposed to heat, automatically sealing all gaps in the event of a fire, effectively blocking smoke and toxic gas penetration and buying precious time for evacuation.

Extreme Scenario Protection

1.Emergency Support: Even under high-temperature scorching, the door retains its complete shape without deformation or failure, ensuring evacuation routes or safe zones can be closed or opened, providing critical support for emergency rescue.

2.Long-Lasting Performance: Cast aluminum substrates feature natural high-temperature and corrosion resistance, remaining stable in complex environments over the long term, with no degradation in fire resistance or structural strength over time.
