As a leading China fire door manufacturer, we design steel fire doors that meet rigorous safety standards while maintaining structural integrity and ease of installation.
* Fire-rated up to 3 hours for maximum safety protection
* 1-3/4″ thick construction with non-handed design featuring reversible hinge plates for flexible installation
* Interlocking seam design enhances structural rigidity, durability, and fire containment
* Factory applied rust inhibiting primer ensures long-term corrosion resistance
* Fire-rated glass options available for vision lites to maintain visibility while preserving fire protection
These commercial fire doors are built with heavy-duty 18-gauge galvanized steel that provides exceptional strength and fire resistance. The door core is filled with fireproof cotton or rock wool insulation, which expands under heat exposure to seal gaps and prevent fire and smoke migration. This design makes our steel fire door an ideal choice for building exits, stairwells, corridors, and other critical fire separation areas.

Why Choose Our Fire Rated Steel Doors
Fire rated steel doors play a vital role in keeping people safe and minimizing property damage during a fire emergency. Labeled fire doors control the spread of fire and smoke for up to 3 hours, providing critical time for evacuation and emergency response. Metal fire doors are an economical alternative to wood fire doors when more than a 20-minute rating is required. Steel is the sole door material capable of delivering a 3-hour fire-rating, making it the preferred choice for high-risk commercial applications.
As a trusted China fire door manufacturer, we specialize in producing commercial fire doors that combine safety, durability, and cost-effectiveness. Our steel fire door products are designed to withstand extreme temperatures while maintaining their structural integrity. The doors are tested to ensure they meet or exceed fire safety regulations, providing peace of mind for building owners, facility managers, and safety inspectors.
* 20, 45, 60, 90 Minute or 3 Hour fire rating labels available
* Heavy-duty 18-gauge steel construction for maximum strength
* Rigid honeycomb or polystyrene core with fireproof cotton or rock wool infilling
* Waterproof and heat insulation properties for enhanced building protection
* Suitable for exit doors, emergency stairwells, and fire separation walls
Our fire rated steel doors are ideal for a wide range of applications including hospitals, schools, hotels, shopping malls, warehouses, manufacturing plants, and office buildings. The doors can be customized in size, color, and configuration to meet specific project requirements. Surface treatments include heat transfer printing or powder coating in colors such as white, red, blue, or custom options to match your architectural design.

FAQ
Q1: Are there any problems with the glass inside? Having steam or going foggy?
A: Usually, we use 5mm+6A+5mm double glass. You can be assured that our fire rated steel doors with vision lites feature professionally manufactured double glass with no steam or fog issues between the panes. The sealed glass units maintain clarity throughout their service life.
Q2: All these doors and windows come with frames to mount on walls?
A: Yes, all commercial fire doors include complete frames ready for wall installation. Our steel fire door systems are delivered with mounting frames that simplify the installation process and ensure proper fit.
Q3: The glass is broken with no reason, I'm afraid the rest will be broken?
A: Glass breakage only occurs due to impact force. Fire rated steel doors with glass lites use tempered fire-rated glass that will not break spontaneously. Each glass panel is carefully inspected before installation.
Q4: What type of fly screen you could supply?
A: While fly screens are typically associated with standard doors and windows, our focus as a China fire door manufacturer is on fire safety products. For fire rated steel doors, ventilation accessories must maintain the fire rating. We can provide guidance on compatible accessories that do not compromise the fire protection integrity of commercial fire doors.
Q5: What are the advantages of choosing steel fire doors?
A: Steel fire doors offer superior advantages including the highest fire rating available (up to 3 hours), excellent structural strength, cost-effectiveness compared to equivalent-rated wood doors, resistance to warping and deterioration, minimal maintenance requirements, and proven performance in fire testing. These benefits make fire rated steel doors the preferred choice for commercial applications requiring maximum fire protection.
Q6: What kinds of packing do you have?
A: As a professional China fire door manufacturer, we offer three packing options for commercial fire doors: bubble bag for full container shipments, bubble bag plus wooden frame for standard protection, and bubble bag plus wooden case for maximum protection. The wooden case option is recommended for bulk cargo and shipments to countries with strict import requirements such as USA, Australia, and European nations, as it provides superior protection for steel fire door products during international transport.
