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.
