Fire gates are one of the most popular and frequently used types of fire barriers. They are capable of preventing the spread of fire during a fire. In addition, they prevent unauthorized access and participate in the design of houses, structures for various purposes and the territories adjacent to them.
Variety of fire gates
They are of the following types: retractable, sectional and hinged. Fire resistance of all types of gates is achieved by the fact that they are made of special fire-resistant material or processed with fire-resistant means.
Retractable fire gate
This type of fire gate has one indisputable advantage - they significantly save usable space. When you open the gate, it rolls back along the fence and completely releases the entrance to the courtyard (they have no height restrictions).
Fire sliding gates by design type there can be 2 types:
- Single-leaf gates that can open along the doorway in any direction. This will significantly save space inside or outside the building. This type of gate is often put on production.
- Double-leaf sliding fire gates, opening along the opening in different directions. This type around the perimeter of the door is equipped with additional gaskets to prevent the ingress of smoke and other combustion products into the building. In addition, they perform thermally insulating functions. In this regard, in enterprises that have an increased fire hazard and a high intensity of movement, double-leaf fire gates become an indispensable element.
The main functions of sliding gates
This type of fire gate performs the following functions:
- Protective. Gates - excellent protection of the premises from the penetration of unauthorized persons.
- Heat insulating. Able to retain heat in the room and prevent it from leaving.
- Fire fighting. This function prevents the spread of fire.
- Evacuation. When you open the doors, a sufficiently large opening opens, allowing people to freely evacuate from this room. In addition, the opening gives firefighters free access to the fire.
Sectional fire doors
Sectional fire doors practically do not differ from ordinary sectional doors . Their only distinguishing feature is the filler located inside the panels. In some, it is foamed polyurethane foam, which has a high density, and in others, basalt mineral wool, which has flame retardant properties (it does not lend itself to burning and does not melt, does not allow smoke, and has a low thermal conductivity).
Product design
A special sealing profile is located around the perimeter of this type of gate, which is made of non-combustible material. This ensures a tight fit and sealing of the opening. It has a special sealing petal, which ensures a tight fit of the canvas and the opening to each other.
Scope of application
As a rule, this type of gate is installed in rooms where an emergency situation with fire may occur, which means that there will be a need for urgent evacuation of personnel, protection of material assets and the speedy elimination of the fire. Sectional fire doors are designed to protect against smoke and fire, in order to prevent them from spreading. They are embedded in the opening of the premises in factories, in various workshops, dryers, foundries and melting rooms, etc.
Swing gates
They are installed in any places. They are distinguished by ease of operation and maintenance, high reliability and durability. Their only drawback is that a sufficient amount of space is necessary for their opening, which can be carried out both inside and towards the street.
Oar fire gates are often equipped with a fire door, which opens in the same way as the gates themselves.
A separate category of swing type constructions is fire metal gates. For their external design, special metal plates are used, which are highly durable.
