Fire doors refer to doors that can meet fire resistance stability, integrity and thermal insulation requirements within a certain period of time.

Specially used to isolate fire sources in housing construction. In the event of a fire, people can obtain escape opportunities through fire doors.

But many people are completely unaware of the importance of fire doors, and there are many misunderstandings about their cognition and behavior:

1. For convenience, keep the normally closed fire door open all year round

2. There are piles of debris near the fire door

3. Lock the fire door or change it into a security door without permission

These misunderstandings will encourage the spread of fire and block escape routes in the event of a fire, so everyone must maintain safety awareness at all times.

Wood fire doors, steel fire doors, steel and wood fire doors and other material fire doors, our commonly used fire doors The doors are wooden fire doors and steel fire doors.

2. According to fire resistance, it can be divided into:

Insulated fire doors (Category A), partially insulated fire doors (Category B) and non-insulated fire doors (Category C).

The fire doors we usually refer to are thermally insulated fire doors, which can meet both fire-resistant integrity and thermal insulation requirements within a specified time. Fire doors have smoke-proof properties when closed.

There are three commonly used fire resistance grades for insulated fire doors: Class A (1.5h), Class B (1.0h) and Class C (0.5h).
