Steel Fire-rated Door

Product Overview

The steel fire-rated door QA-GFM-003 is a heavy-duty fire protection and security solution engineered for commercial, industrial, and civil buildings. Made of high-quality steel materials and filled with professional fire-proof insulation materials, this door features exceptional fire resistance, anti-theft performance, and durability. Its simple and sturdy design adapts to various architectural styles, while built-in smoke-proof strips and emergency escape devices provide comprehensive safety guarantees for personnel and property.

Structure & Materials

Door Frame

Formed by bending high-quality cold-rolled steel plate with a thickness of 1.2-2.0mm. The integrated bending process enhances structural rigidity, ensuring the frame is firm and durable. It provides stable support for the door leaf and achieves a tight connection with the wall, preventing fire and smoke leakage from gaps.

Door Leaf

Skeleton: Welded by high-strength steel profiles, the skeleton delivers excellent load-bearing capacity and stability, resisting deformation even under high temperatures and external impacts.

Panel: Uses cold-rolled steel plate with a thickness of 0.8-1.2mm. The surface is treated with anti-corrosive coating, improving rust resistance and service life.

Filling Materials: Filled with fire-proof rock wool and perlite—low thermal conductivity materials that effectively block heat transfer and inhibit flame spread.

Hardware & Safety Components

Basic Hardware: Includes high-strength hinges (bearing door leaf weight for flexible opening/closing), anti-theft door locks (resisting forced entry), door closers (ensuring automatic closing), and sequencers (guaranteeing orderly closure of double doors).

Special Safety Parts: Equipped with fire-proof smoke-proof strips between the door frame and leaf to block toxic smoke leakage. Some models feature emergency escape push rod locks for quick evacuation in emergencies.

Technical Specifications

Key Performance Features

Exceptional Fire & Heat Insulation

The solid steel structure and low-thermal-conductivity filling materials form a reliable fire barrier. During a fire, it effectively prevents flame spread and heat transfer, minimizing damage to adjacent areas and protecting equipment and materials.

Reliable Anti-Theft Protection

The thick steel panel, high-strength steel skeleton, and anti-theft door lock work together to resist external impacts and forced entry. It integrates fire protection and anti-theft functions, safeguarding indoor property safety.

Effective Sound Insulation

The sealed structure (equipped with sealing rubber strips) and dense steel material reduce sound transmission. It blocks external noise, creating a quiet environment for offices, workshops, and residential stairwells.

Enhanced Safety Guarantees

Fire-proof smoke-proof strips prevent toxic smoke leakage, ensuring clean air for evacuation routes. Emergency escape push rod locks allow quick door opening without keys, improving evacuation efficiency in emergencies.

Applicable Scenarios

Commercial Buildings

Ideal for shopping malls, hotels, office buildings, and other high-traffic areas. Installed in fire prevention zones, stairwells, and front rooms to separate fire-prone areas and prevent cross-area fire spread.

Industrial Buildings

Widely used in factories, workshops, and warehouses as fire separation facilities. It adapts to harsh industrial environments, resisting dust, impact, and corrosion while maintaining stable fire resistance.

Civil Buildings

Applied in stairwells, pipe wells, and entrance halls of residential buildings, hospitals, and schools. It enhances the building’s fire safety level and provides additional anti-theft protection for residents.

Advantages & Certifications

Multi-Functional Protection: Combines fire resistance, anti-theft, sound insulation, and heat insulation, offering comprehensive safety solutions.

Durable & Corrosion-Resistant: High-quality steel and anti-corrosive coating ensure a long service life, suitable for harsh environments.

Authoritative Certifications: Holds national and international fire safety certifications, complying with building fire codes.

Safe & Reliable: Equipped with smoke-proof strips and emergency escape devices, maximizing personnel safety during emergencies.

Installation & Maintenance

Standard Installation

Installed by professional technicians in accordance with construction specifications. Ensure the door frame is firmly fixed to the wall, with uniform gaps between the door leaf and frame. Test the door closer and sequencer functions to ensure automatic and orderly closure.

Routine Maintenance

Monthly Inspection: Check the door’s integrity (no deformation, damage, or rust) and hardware tightness (hinges, locks, etc.). Repair or replace faulty parts promptly.

Cleaning Methods: Wipe the surface with a clean wet cloth to remove dust and stains. Avoid corrosive cleaners that damage the anti-corrosive coating.

Function Testing: Regularly test door closers, sequencers, and emergency escape devices. Ensure the door closes smoothly and the escape push rod works normally.

Rust Prevention: For outdoor or humid environments, inspect the anti-corrosive coating annually. Touch up paint on scratched areas to prevent rust.
