Factory Price Heavy Duty Fire Rated Door Steel for Fire Escape Exit

A fire door is not just a barrier. It is the last line of defense between a blaze and human lives.

ZHUOHONG's Heavy Duty Fire Rated Steel Door is engineered for one mission: buying critical minutes during a fire emergency. Built with galvanized steel armor, mineral fire-resistant core, and certified intumescent seals, this door meets international fire safety standards (GB/CE/UL) while surviving the brutal demands of daily commercial traffic.

And yes – it comes at a factory-direct price because we manufacture it ourselves.

Why Most "Fire Doors" Fail – And How We Solved It

Common Problem ZHUOHONG Solution
Warped door leaves after 2-3 years 1.5mm galvanized steel leaf – rigid, rust-resistant, impact-proof
Flimsy frames that sag under weight 100×45mm reinforced frame with 1.0mm galvanized steel
Smoke leakage during a fire Advanced intumescent & smoke seals – expand with heat to block toxic gases
Hardware failure in high heat Certified fire-rated hinges, lockset, door closer, and bolt – rated for extreme temperatures
Rust in humid environments Powder coating or wood grain PVC film – protects against moisture and corrosion

A fire door is only as strong as its weakest component. We don't cut corners.
