Products Description
Comprehensive Fire Protection Engineering
Fire rated steel doors play an essential role in protecting human life and minimizing property damage during fire emergencies. These labeled fire resistant doors effectively control the spread of fire and toxic smoke for durations up to 3 hours, providing crucial time for safe building evacuation and firefighting response. Commercial fire doors manufactured from steel offer an economical yet highly effective alternative to wooden fire doors when protection ratings exceeding 20 minutes are required.
Steel remains the only door material capable of delivering a full 3-hour fire-rating, making it the preferred choice for high-risk commercial buildings, industrial facilities, hospitals, schools, and multi-story residential complexes. The inherent strength and non-combustible properties of steel provide unmatched reliability in fire barrier applications.
* Available in 20, 45, 60, 90-minute, and 3-hour fire rating classifications
* Heavy-duty 18-gauge steel construction for superior impact resistance
* Rigid honeycomb or high-density polystyrene insulating core
* Intumescent sealing systems that expand during fire exposure
* Pre-hung configurations available for faster installation
* Compatible with panic hardware, closers, and access control systems
The steel fire door design incorporates precision-engineered components that work together as a complete fire barrier system. The door leaf, frame, hardware, and sealing components are tested and listed as a complete assembly to ensure optimal performance during actual fire conditions. This integrated approach guarantees that every element functions properly when protection is needed most.
Our fire rated steel doors feature factory-welded construction with reinforced corners and edges to prevent warping and maintain dimensional stability throughout the product lifecycle. The galvanized steel substrate resists corrosion even in harsh environments, while the factory-applied primer provides an ideal surface for field painting to match any architectural color scheme.

FAQ
Q1: Are there any problems with the glass inside? Having steam or going foggy?
A: Our fire rated steel doors with vision lites use professionally manufactured 5mm+6A+5mm double glass units. These are hermetically sealed with no risk of condensation, steam, or fogging between the glass panes. The sealed units maintain clarity throughout their service life.
Q2: All these doors and windows come with frames to mount on walls?
A: Yes, every steel fire door is supplied complete with matching fire-rated frames designed for direct wall installation. The frame assemblies include all necessary anchoring provisions and are ready for mounting in masonry, concrete, or steel stud wall openings according to installation specifications.
Q3: The glass is broken with no reason, I'm afraid the rest will be broken?
A: Fire-rated glass in our commercial fire doors is manufactured to withstand both fire exposure and normal impact. Glass breakage only occurs when subjected to significant external force or improper installation stress. The material does not break spontaneously under normal operating conditions.
Q4: What type of fly screen you could supply?
A: While fire resistant doors do not typically require insect screens due to their application in interior fire barrier locations, we can supply three screen styles for compatible door types: roller screens for hinged configurations, sliding screens for sliding doors, and folding screens for wide openings. Screen materials include nylon, stainless steel, and reinforced security mesh.
Q5: PVC and aluminum, which is better?
A: For fire rated applications, steel fire door construction significantly outperforms both PVC and aluminum. Steel provides superior fire resistance, structural strength, and the ability to achieve 3-hour fire ratings that neither PVC nor aluminum can match. While PVC offers thermal insulation and aluminum provides corrosion resistance, only steel delivers the fire barrier performance required for life safety applications.
Q6: What kinds of packing do you have?
A: We offer three protective packaging options for fire rated steel doors: bubble wrap protection for full container shipments to maximize loading capacity; bubble wrap plus wooden frame reinforcement for standard shipments; and bubble wrap plus full wooden crate enclosure for maximum protection during less-than-container loads and shipments to regions with strict fumigation requirements such as the USA, Australia, and European markets.
