China Nylon Flame Retardant Filament Brush Strip For Fire Doors Manufacturer

Introduction

This brush strip is made from a metal back and flame retardant nylon filaments. During installation, the brush strip is usually fitted into a aluminium holder, which allows it to be securely mounted around the door frame, and then fills the small gaps between the door and the frame, creating effective seal.

Why Brush Strips Are Important For Fire Doors

Fire doors are typically installed in building corridors, stairwells, and other high-safety areas. Their primary purpose is to slow the spread of fire and block smoke during an emergency, giving people more time to evacuate safely.

However, even when a fire door is properly installed, small gaps between the door and the wall or frame are almost unavoidable. These gaps can become pathways for smoke to travel quickly from one area to another.

This is where brush strips for fire doors are important here.

By installing a fire door seal brush around the edges of the door, these gaps can be effectively sealed. The flexible brush filaments fill the space and prevent smoke from passing through, improving the door’s ability to contain fire and smoke.

Another important safety feature is the material itself. The filaments used in our flame retardant brush strip contain flame-retardant additives. When exposed to open flame, the filaments do not support combustion, which helps maintain the integrity of the door seal during a fire.
