A heavy-duty exterior door hinge is required for use in commercial applications where the door is used as a primary entrance to the building. It is also required to ensure that the door is able to withstand extreme conditions. The best doors on the market are usually rated by one to five on a five-point scale for their strength and fire resistance. The UL listed door hinge consists of a steel tube covered by melamine, a safety-textured layer that prevents corrosion and makes it resistant to rust, stains, and dirt. They should be designed with a one-inch interior diameter steel tube that can be formed into a solid unit when heated, to ensure proper insulation.
When purchasing a door with the UL Listed door hinge, there are a few things to consider. First and foremost, the door must have a tapered flange to prevent the weight of the person walking up the door from tipping the latch assembly over. Additionally, the flange must be adequately reinforced so that it can withstand someone slipping through an opening that is too narrow for them to walk into. A good test to look for when trying to determine the overall strength of a door is to gently strike the bottom of the door with your fist. If the bottom hits the floor or does not bounce back at all, then the door is too weak and should be replaced with a new one.

UL approved fireproof door hinges are a great addition to any home or office building. However, the most important factor to consider before purchasing a door hinge is to make sure that the door is not only fireproof, but that it also functions properly. The next time you are at your local hardware store, look for a UL listed door hinges assembly.
