The Life-Saving Importance of 2-Hour Fire-Rated Doors

A 2-hour fire-rated door is precisely what its name suggests: a door that can withstand the intense heat and flames of a fire for up to two hours, such as our fire-rated metal double doors. This rating is a testament to the door's ability to act as a barrier, preventing the fire from spreading to adjacent areas. It's crucial to note that these doors are rigorously tested and certified by relevant authorities to ensure they meet stringent fire safety standards.

2-Hour Fire Door 
Construction & Features

2-hour fire doors are not your ordinary doors; they are engineered with fire-resistant materials that can withstand extreme temperatures. They typically consist of multiple layers of fire-resistant core material enclosed within heavy-duty steel or other fire-resistant materials. This construction provides exceptional heat insulation and integrity, preventing the fire from penetrating the door.

Moreover, 2-hour-rated doors often come equipped with fire-rated hardware, including hinges, locks, and latches, designed to withstand the high temperatures of a fire. This ensures the entire door assembly maintains its integrity during a fire event.
