What Are EI30, EI60, EI90 & EI120 Fire Rated Steel Doors?
Understanding Fire Resistance Ratings
Fire-rated steel doors are classified according to the amount of time they can resist fire, smoke, and heat transfer.
The “E” classification refers to integrity, meaning the system prevents flames and smoke from passing through.
The “I” classification refers to insulation, meaning the system also limits heat transfer to the non-fire side.
Fire Resistance Classifications
- EI30 steel doors — fire protection for 30 minutes
- EI60 steel doors — fire protection for 60 minutes
- EI90 steel doors — fire protection for 90 minutes
- EI120 steel systems — fire protection for up to 120 minutes
These classifications are essential for modern buildings requiring compartmentation, protected escape routes, and advanced passive fire protection.

Frequently Asked Questions
What Is the Difference Between EI30, EI60, EI90 & EI120?
The number indicates the duration of certified fire resistance in minutes.
EI30 = 30 minutes
EI60 = 60 minutes
EI90 = 90 minutes
EI120 = 120 minutes
Higher classifications are typically required for larger commercial buildings, public infrastructure, and critical fire compartmentation zones.
What Does EI Mean in Fire-Rated Steel Doors?
The “E” classification refers to integrity, meaning the door prevents flames and smoke from passing through.
The “I” classification refers to insulation, meaning the system also limits heat transfer to the non-fire side.
Together, EI classifications provide comprehensive passive fire protection.
Are Fire Rated Steel Doors Available with Glass?
Yes. PORTAMET manufactures glazed fire-rated steel doors using certified fire-resistant glass systems.
These systems allow for slim steel profiles and large glazed areas while maintaining certified fire protection.
Can Fire-Rated Steel Doors Be Used Externally?
