Key features and specifications of Fire Resistant Steel Doors

  • July 17, 2023

Fire-resistant steel doors are designed to provide enhanced fire protection in various commercial, industrial, and residential settings.

They are constructed using high-quality steel materials and equipped with fire-resistant components to withstand fire and prevent its spread.

Here are some key features and specifications that are often associated with fire-resistant steel doors:

Fire Rating

Fire-resistant steel doors are classified based on their fire rating, which indicates the duration for which the door can withstand fire. Common fire ratings include 30 minutes, 60 minutes, 90 minutes, and 120 minutes, indicating the time the door can resist fire and maintain its structural integrity.

Steel Construction:

These doors are typically constructed using high-quality galvanized or stainless steel, which offers excellent strength, durability, and fire resistance. The steel core provides structural stability and ensures the door remains intact during a fire.

Fire-Resistant Core:

Fire-resistant steel doors feature a fire-resistant core material, such as mineral wool or ceramic fiberboard. This core material helps to insulate the door and prevents the transfer of heat during a fire, thereby slowing down the spread of flames.

Intumescent Seals:

These doors often include intumescent seals around the edges, which expand when exposed to heat, creating a tight seal between the door and the frame. This seal helps to prevent the passage of smoke, flames, and hot gases, maintaining the integrity of the door assembly.

Hardware and Accessories:

Fire-resistant steel doors come with specialized fire-rated hardware and accessories. This includes fire-rated hinges, closers, locks, panic bars, and vision panels. These components are designed to withstand high temperatures and maintain the door’s fire resistance.

Testing and Certification:

Reputable fire-resistant steel doors undergo rigorous testing and certification by recognized fire safety organizations. Look for doors that comply with industry standards and certifications, such as UL (Underwriters Laboratories), EN (European Norms), or FM Global.

Customization Options:

Fire-resistant steel doors can be customized to suit specific requirements. They are available in various sizes, designs, finishes, and configurations, including single or double doors, with or without glazing options.

Additional Features:
Some fire-resistant steel doors may offer additional features such as sound insulation, thermal insulation, and security enhancements. These features can provide added benefits in terms of noise reduction, energy efficiency, and protection against forced entry.
