PRODUCT FEATURES
Outstanding Fire Resistance
Manufactured according to National Standards, steel fire-rated doors come with various fire ratings (e.g., Class A, B, C), capable of withstanding high temperatures for over 210 minutes and effectively preventing fire spread.
Excellent Smoke Sealing
The sealed design of the door frame and leaf, along with high-temperature expansion sealing strips, ensures effective smoke control during a fire, reducing harm caused by toxic fumes.
Durable and Robust
Made with cold-rolled steel plates, offering high compressive and impact resistance while effectively withstanding external forces, thereby extending the service life.
Multi-Layer Structure Design
Filled with proprietary patented fireproof materials (e.g., magnesium oxide, magnesium chloride), enhancing fire resistance, corrosion resistance, and soundproofing for a balance between safety and comfort.
Aesthetic Appearance
Steel fire-rated doors can be customized with various surface treatments (e.g., powder coating, transfer printing) to blend seamlessly with diverse architectural and interior styles.
Convenient Installation and Maintenance
Professionally designed installation process for fast and easy setup; minimal maintenance required without complicated routines.
STRUCTURAL COMPONENTS
Door Frame: Made from cold-rolled steel, ensuring stability and safety.
Door Leaf: Typically consists of double-layered steel sheets filled with proprietary patented fireproof materials (e.g., magnesium oxide, magnesium chloride) for enhanced fire and corrosion resistance.
Sealing Strips: Positioned at the interface between the door frame and leaf; expands under high temperatures to block smoke and flame penetration.
Locks and Hinges: Equipped with high-temperature-resistant locks and hinges, ensuring smooth operation and enhanced security.
How to Choose the Right Steel Fire-Rated Door?
Choosing the appropriate steel fire-rated door is crucial for ensuring fire safety in buildings. Here are some key factors to consider:
-
Fire Rating
Understanding Fire Ratings:Based on National Standards, fire-rated doors are categorized into Class A (120 minutes), Class B (60 minutes), and Class C (30 minutes). Select the rating according to the building’s fire safety requirements.Applications:For public spaces with high foot traffic, Class A doors are recommended. For general passageways or storage rooms, Class B or C may suffice. -
