emergency exit door
Emergency exit doors are a vital component in modern building design, serving as critical safety features that provide secure and efficient egress routes during emergencies. Whether in commercial, industrial, or residential settings, these doors are engineered to withstand harsh conditions and ensure the safety of occupants. This article delves into the significance, design, benefits, and maintenance of steel exit doors.
Steel Emergency exit doors are heavy-duty doors constructed from steel, designed primarily for use in emergency situations. They are typically installed in commercial buildings, schools, factories, and other public spaces to facilitate safe and rapid evacuation. Unlike standard doors, steel exit doors are built to meet specific safety codes and regulations, often incorporating features like fire resistance and panic hardware.
Steel exit doors are engineered to endure high levels of wear and tear, making them ideal for high-traffic areas. Their robust construction minimizes damage from impacts, weather, and corrosion.
Many steel exit doors come with fire ratings, providing crucial protection against smoke and flames. This feature is essential in ensuring that exit routes remain accessible during a fire.
Fire doors play a crucial role in fire safety systems worldwide, designed to prevent the spread of fire and smoke and ensure safe egress. Different countries have established their own codes and regulations, often influenced by international standards. Here’s an overview of the key safety codes and regulations governing fire doors across various regions:
| Country | safety codes and regulations |
|---|---|
| United States | National Fire Protection Association (NFPA)NFPA 80: Covers the installation, inspection, testing, and maintenance of fire doors.NFPA 101: The Life Safety Code addresses egress requirements and fire door applications in buildings.International Building Code (IBC)Governs construction and occupancy requirements, detailing where fire doors must be used.Underwriters Laboratories (UL)UL 10B and UL 10C: Standards for fire door performance and testing. |
| Canada | National Building Code of Canada (NBC)Specifies requirements for fire safety, including fire door assemblies and their ratings.Underwriters Laboratories of Canada (ULC)Similar to UL, ULC sets standards for fire doors, including testing and performance criteria. |
| European Union | EN 1634-1This standard specifies test methods for fire resistance and smoke control of doors.Building RegulationsEach EU country has its own regulations, but they often align with the EU directives, requiring fire doors to meet certain performance and safety criteria.CE MarkingFire doors in the EU must be CE marked, indicating compliance with relevant EU standards. |
| United Kingdom | Building Regulations Approved Document BThis document outlines fire safety regulations, including the installation and use of fire doors in buildings.British Standards (BS)BS 476: A series of tests for fire resistance, including those applicable to fire doors.BS EN 1634: Specifies requirements for fire doors and their performance. |
| Australia | Building Code of Australia (BCA)Sets out the requirements for fire safety, including specifications for fire door assemblies.Australian Standards (AS)AS 1905.1: Specifies the performance and testing requirements for fire-resistant doors. |
Steel exit doors often include panic bars or exit devices that allow for quick, one-handed operation. This design is crucial during emergencies when time is of the essence.
Many emergency exit doors are equipped with self-closing devices to prevent doors from being left open unintentionally. This is especially important in fire-rated doors to prevent the spread of smoke or fire.
Emergency exit doors must be clearly marked with visible, universally recognized exit signs. These signs are often illuminated and should be visible from a distance, indicating the direction of escape. The signs should also be accompanied by a "push bar" symbol, where applicable.
The size of an emergency exit door is critical. It should be wide enough to accommodate a large number of people evacuating at once, minimizing the risk of congestion or panic. Building codes often stipulate minimum widths based on the size of the building and the occupancy load.For high-occupancy areas, doors should be wider and may have multiple exit doors.
The steel fire door frame is made of high-quality galvanized steel sheet metal, which is bent and welded. The frame can be made into a welded frame or a knock-down frame. It adopts a 3mm hinge reinforcement plate and is equipped with different anchor for installation on different wall types. At the same time, high-expansion fire-resistant strips are pasted around the frame.
The steel fire door leaf is made of high-quality galvanized sheet as the face panel, with mineral fireproof board as the fireproof and heat insulation core material; 3mm thick hinge reinforcement plate is welded inside; it is glued with fireproof PU glue and cold pressed for more than 6 hours under a pressure of 1500 MPa. Finally, the joints around the perimeter are welded with a laser welding machine.
Finally, the steel fire door is equipped with fire-rated certified hinges, door closers and escape locks, and is inspected and packaged for storage.
Optional solid color
The surface is covered with a layer of pvc film, sleeved with bubble wrap, and then packed into a 7-layer corrugated cardboard box and wrapped with strapping tape; the secure packaging can reduce the damage caused by scratches and collisions during on-site handling.
Same as standard wooden door packaging,door pack with the foam corner and edge protection, the surface of a layer of sponge film, and then put into a cardboard box, wrapped with tape; safe packaging can reduce the damage brought about by scratches and collisions in the handling process on site
Knock-down packaging reduces the volume of packaging, increases the number of loaded goods, reduces transportation costs, especially for large-size metal doors, both knock-down packaging reduces the weight of a single piece of packaging, which is easy for on-site workers to carry, and reduces the size of the package, which avoids the limitations of the size of the container or the size of the access to the site, which makes it easy to carry through.
After the standard packaging, and then put each door into the wooden box, usually the wooden box is made of plywood board or particle board, the bottom of the wooden box has a base can be forklift truck work; Obviously the wooden box packaging increases the cost, but it also brings a lot of benefits, 1 . Convenient for loading and unloading 2. Avoiding damage to the product from collision during international transport, especially for doors with glass.
