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
Made from cold-rolled steel, ensuring stability and safety.
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.
Positioned at the interface between the door frame and leaf; expands under high temperatures to block smoke and flame penetration.
Equipped with high-temperature-resistant locks and hinges, ensuring smooth operation and enhanced security.
