Stainless Steel Fire Door

Product Overview

The Stainless Steel Fire Door QA-BXG-002 is a high-performance safety door designed for spaces requiring strict fire protection and security standards. Combining durability, fire resistance, and modern aesthetics, this door is engineered to stop fire and smoke spread during emergencies while blending seamlessly with various architectural styles. As a core product for fire safety, it prioritizes reliability and long-term usability, making it a top choice for commercial, industrial, and public facilities.

Structure & Materials

Door Panel Material

The door body is constructed with high-strength stainless steel plate (304 or 316 grade), featuring excellent corrosion resistance and mechanical strength. After precision grinding and polishing, the surface achieves a smooth, glossy finish that resists rust, acid, and alkali erosion—ideal for harsh environments like underground parking lots or outdoor areas. The stainless steel plate thickness ranges from 1.2mm to 1.5mm, ensuring structural stability and impact resistance.

Internal Filling Material

The core of the door is filled with fire-resistant rock wool, a high-efficiency fireproof and thermal insulation material. With a moderate density of 120kg/m³, it balances door weight and fire protection performance, effectively blocking heat transfer and preventing fire spread for up to 120 minutes (depending on the fire rating).

Hardware Components

Equipped with high-temperature resistant hardware, including anti-theft door locks and heavy-duty hinges. The lock core adopts advanced anti-picking technology, while hinges are made of stainless steel with high load-bearing capacity (up to 80kg per hinge), ensuring smooth opening and closing even after frequent use. Fireproof sealing strips are installed around the door frame to enhance smoke and heat insulation.

Technical Specifications

Key Performance Features

Fire Protection Performance

Passed strict fire tests and certifications, the Stainless Steel Fire Door effectively isolates fire and smoke within the specified time, providing valuable evacuation time. The fireproof sealing strip expands at high temperatures to block gaps, preventing hot air and smoke leakage.

Security & Durability

The high-strength stainless steel structure resists deformation and impact, while the anti-theft lock core prevents violent opening. Corrosion-resistant properties ensure the door maintains performance and appearance for over 15 years in humid or outdoor environments.

Decorative Versatility

With a simple modern design, the smooth stainless steel surface and tough border lines complement architectural styles like minimalist, industrial, or European classical. It enhances the overall quality of buildings while fulfilling safety functions.

Applicable Scenarios

Commercial Buildings

Ideal for shopping mall fire partitions, office building stairwells, and high-rise building fire exits—areas requiring strict fire safety and high traffic resistance.

Industrial Facilities

Suitable for factory workshops, warehouses, and power distribution rooms, where fire risks and harsh environments demand durable, corrosion-resistant fire protection solutions.

Public Facilities

Widely used in hospitals, schools, hotels, and railway stations. Crowded places where rapid evacuation and long-lasting fire protection are critical.
