Classification of Fireproof Doors

Fireproof doors are categorized based on their fire resistance rating, material, and usage. 

1. Classification by Fire Resistance Rating

Fireproof doors are rated based on the duration they can withstand fire and prevent its spread. Common ratings include:

- EI30: Resists fire and smoke for 30 minutes

- EI60: Resists fire and smoke for 60 minutes

- EI90: Resists fire and smoke for 90 minutes

- EI120: Resists fire and smoke for 120 minutes

- EI180: Resists fire and smoke for 180 minutes

"E" stands for Integrity (ability to prevent flames and hot gases).

"I" stands for Insulation (ability to limit temperature rise on the non-fire side).

2. Classification by Material

Fireproof doors are made from various materials, each offering different levels of fire resistance and aesthetic appeal:

- Steel Fireproof Doors:

  - Made from galvanized steel or stainless steel.

  - Highly durable and offers excellent fire resistance.

  - Commonly used in industrial and commercial buildings.

- Wooden Fireproof Doors:

  - Made from fire-treated timber or wood composites.

  - Combines fire resistance with a traditional aesthetic.

  - Often used in residential and decorative applications.

- Glass Fireproof Doors:

  - Made from fire-rated glass with steel or aluminum frames.

  - Provides fire resistance while allowing visibility and natural light.

  - Suitable for modern offices, hotels, and public buildings.

- Aluminum Fireproof Doors:

  - Lightweight and corrosion-resistant.

  - Often used in commercial and institutional buildings.

- Composite Fireproof Doors:

  - Made from a combination of materials (e.g., steel core with wood or glass panels).

  - Offers a balance of fire resistance, durability, and design flexibility.

3. Classification by Usage

Fireproof doors are designed for specific applications based on their location and purpose:

- Industrial Fireproof Doors:

  - Used in factories, warehouses, and industrial facilities.

  - Designed to withstand high temperatures and harsh environments.

- Commercial Fireproof Doors:

  - Installed in offices, shopping malls, and hotels.

  - Focus on both fire safety and aesthetic appeal.

- Residential Fireproof Doors:

  - Used in homes, apartments, and villas.

  - Prioritizes safety while blending with interior design.

- Institutional Fireproof Doors:

  - Installed in schools, hospitals, and government buildings.

  - Meets strict safety regulations and standards.

- Emergency Exit Fireproof Doors:

  - Designed for stairwells, corridors, and emergency exits.

  - Ensures safe evacuation during fire emergencies.

4. Classification by Opening Mechanism

- Single-Swing Fireproof Doors: Open in one direction.

- Double-Swing Fireproof Doors: Open in both directions.

- Sliding Fireproof Doors: Slide open horizontally.

- Rolling Fireproof Doors: Roll up vertically, often used in industrial settings.

By understanding these classifications, you can select the appropriate fireproof door based on fire resistance requirements, 

material preferences, and specific usage scenarios.
