How important is the fire rating of your metal frame?
That depends - on where you're using the frame as well as on national and local fire codes. At Mesker, we offer 3-hour, 1 and half hour, 60-minute, three-quarter hour or 20-minute fire rated doors.

In many cases, the door fire rating needs to be at least three-quarters of your wall fire rating. So, if your wall fire-rating is 4 hours, your door fire-rating needs to be at least 3 hours. Just click on the links above for more information.
