The Steel Thermal Fire Door is a fully insulated A-class fire door built to handle both fire integrity and thermal insulation simultaneously. Built from premium cold-rolled steel and shaped using cold-pressing techniques, it features a solid structural design and high mechanical strength. For modern buildings, it serves as a critical passive fire protection component-delivering reliable safety, long-term durability, and effective heat containment.
Where It's Used
These doors are essential in any building requiring strict fire compartmentation and heat barriers:
- Escape stairwells and fire exits in high-rise residential and commercial buildings
- Fire partitions between different areas (like hotel corridors or hospital wards)
- Electrical and mechanical rooms (generator rooms, transformer stations, pump rooms)
- Kitchens and restaurants where high heat and fire risks are present
- Data centers and server rooms needing both fire blocking and equipment protection
- Parking garages and industrial plants subject to heavy daily use
- Spaces needing noise control-our fire+acoustic version cuts sound transmission while maintaining the thermal barrier
Key Features
Reliable Fire & Thermal Insulation
As an A-class fire door, it provides complete thermal insulation, blocking flames and significantly limiting temperature rise on the unexposed side. Standard ratings include Class C (≥0.5h), Class B (≥1.0h), and Class A (≥1.5h), with 2.0h and 3.0h options available for specific project needs. All ratings are certified by national fire testing centers in line with standard fire resistance tests for door and shutter assemblies.
Heavy-Duty Steel Construction
We fabricate the door leaf and frame from high-grade galvanized or cold-rolled steel, with thicknesses that meet or exceed national standards. The internal cavities are filled with high-density, non-combustible insulation (such as expanded perlite, ceramic fiber, or magnesium boards). This fill stays intact without cracking or falling out, even after severe sandbag impact tests. The structure is also specifically designed to resist warping and deformation under high heat.
Smooth Daily Operation & Automatic Closing
Each door comes with heavy-duty fire-rated hinges, a stainless steel fire lock, and an adjustable closer. Keeping daily use in mind, the opening force stays under 80N for effortless operation. For fire safety, every door has a reliable self-closing device that pulls it shut automatically in a fire. Double-leaf setups can be fitted with a sequential closer to ensure both leaves close in the correct order.
Customizable Configurations
We offer a wide range of layouts to fit different architectural needs:
- Single or double leaf
- With or without fire-resistant glazing (vision panels)
- With or without fanlights
- Combined glass and fanlight setups
- Large glass fire doors for better visibility
- Asymmetrical large/small leaf designs
- Combined fire and acoustic insulation versions
- *Note: Glass panels use multi-layer fire-resistant glazing with expansion seals to maintain both integrity and insulation ratings.*
Durable, High-Quality Finishes
Surface options include electrostatic powder coating (available in multiple RAL colors), PVDF coating, or brushed stainless steel cladding for premium projects. These finishes resist corrosion and scratching while being easy to clean. We also offer a wood grain transfer finish that mimics the look of natural wood while keeping the structural strength of steel.
Quality Assurance
All doors are manufactured under ISO 9001 guidelines. Every unit goes through a factory check covering dimensions, surface quality, closing smoothness, and hardware function. Fire resistance testing is handled by third-party accredited labs, following GB 12955 (China) or BS EN 1634 (Europe) based on your project location.
