Hollow metal fire door play a critical role in fire safety. They slow the spread of fire and smoke, giving staff and employees time to evacuate safely. By containing the fire for as long as possible, they also minimize property damage and inventory loss.
Fire doors are rated by how long they can survive direct heat and flames. Testers attach them to a furnace with a controlled fire that builds slowly to over 1500°F, similar to fires in real-world settings, which can escalate quickly. Ratings are based on how long each door lasts, from 20 minutes to three hours.
Hollow metal fire doors are the only ones capable of achieving the maximum three-hour rating. They are a building’s strongest defense against smoke and flame. Consequently, installing them at critical sections inside and outside provides the best protection against fire and other types of emergencies.
Other Advantages of Hollow Metal Fire Doors
Though fire protection remains its primary function, a hollow metal fire door offers several other benefits as well, including:
- Durability. Nothing lasts longer than steel. It can withstand more wear and tear than any other material. As a result, steel doors last longer and require few repairs.
- Security. Steel doors provide better protection against burglars and vandals. They’re resistant to common break-in tools and damage from natural disasters, such as high winds and debris.
- Efficiency. The empty space between door panels acts as insulation, slowing energy loss between rooms within the building and the environment outside. Additional insulation can be installed between the panels, for even greater savings.
Metal doors also blend easily into your building. They’re available in a wide range of finishes and or can be painted to match your color scheme.
