It really is a question of life and death to have fire door types. To develop structures that adhere to the NFPA code, buildings and especially doors and their hinges must undergo periodic fire door assembly inspections. A safe living environment must be created and inspections must be passed by using the proper gear. For secure residential living, our fire-rated door hinges offer the robustness, ADA compliance, and increased safety required. Our fire-rated door hinges are made of stainless steel, so they can readily resist the rigors of regular home usage. In fact, UL-listed our hinges not only attain Grade 1 status, wherein they pass the 1,000,000 cycles test and are certified for a 3-hour fire, but they also do so with little to no wear. You may open doors of any weight with as little as 5 pounds of power when using our fire door hinges. Waterson hinges are ADA compliant and suited for commonly used residential fire-rated doors. They are especially suitable for elderly communities due to their ease of opening. Additionally, Waterson hinges are perfect for wheelchair-access entryways since they readily meet the 78" minimum clearance standard. The finest of both worlds is combined in our fire-rated door hinges. Waterson hinges are a highly functional, long-lasting alternative to ordinary door closers, which exclusively provide hydraulic function.
They combine reliable pneumatic speed control with comfortable hydraulic dampening. In the improbable event that one of our closers develops a leak, the mechanical system will consistently slow down closing and prevent potentially harmful slamming. With optional hold open and door stop capabilities, our closer hinges combine an overhead closer and a hinge into one elegant component. Commercial entrances, gates, and glass doors are perfect applications for Waterson hinges. These closer hinges are simple to install and may be readily adjusted to provide silent, secure shutting while meeting ADA and ICC A117. 1 opening force criteria. The NFPA 80-compliant and UL 3-hour fire-rated Waterson closing hinges are made of stainless steel and may be used for both internal and all-weather outside openings. Check out all of our self-closing options. The fire door hinge is a simple, inexpensive, and wire- and battery-free final line of defense fire safety solution. The device works like a typical door hinge, enabling the door to swing freely as usual. It is designed to be fitted as a top hinge on the different interior doors of a house (for example, bedrooms, baths, and closets).
The device turns on and closes the door, cutting off oxygen to the fire, when it is subjected to temperatures normally encountered in the very early stages of a fire. A closed door also serves as a barrier against heat and poisonous smoke, granting you extra time to flee or call for help. After being turned on, the hinge now behaves like a standard spring hinge, steadily exerting a modest closing force on the door while yet permitting easy reopening. There must be three approved fire hinges on every fire door. All fire door hinges should have a fire identification marking that is clearly visible and be CE certified. If they lack these indicators, then they are ordinary door hinges, and this has to be fixed. Typically, a fire door weighs more than a regular door. A 30-minute fire door normally weighs over 40kg whereas a regular hollow core door weighs around 15kg. When attempting to sustain this much weight, a regular hinge would rapidly wear out, yet fire door hinges have been shown to last for years at a time. The majority of fire doors have a fire door closer fitted, which increases the amount of wear and stress on the hinges. Once again, fire door hinges are examined and created with the additional weight in mind.
A fire door must contain the fire in case of a fire for at least 30 minutes. The door will distort and burn at this point, and there is a substantial differential in air pressure on each flank of the door. A fire door hinge can survive such circumstances when a conventional door hinge cannot. This is because fire door hinges have the following qualities: Fire door hinges are stronger due to their thick steel structure, big hinge areas, large screws, and pinned and capped designs that stop the pin from falling out of the hinge. Fire door hinges are often composed of stainless-steel Grade 13 material. Steel that is strong enough to handle intense pressure, weight, and heat is crucial, and the greater the grade, the stronger the steel. Additionally, Grade 11 and Grade 7 fire door hinges are available, however, they are often used for 30-minute fire doors and may support less weight.
Always ask the producer of the door core what grade of steel was used to test the door A fire door should be placed appropriately if it has a space of 3 to 4 millimeters between the door and the framework and at least three fire door hinges, however, depending on the specification, four may be required. It is crucial to inspect this since the manufacturer's testing of the door core determines where the hinges should be placed on a fire door. The middle hinge of most fire doors is located between the two other hinges, at a maximum distance of 200mm from the top and bottom of the door. Another option is to position two hinges near the top to assist hold the weight, with one hinge at the bottom of the door as described earlier. Four hinges, if utilized, are typically evenly spaced apart.
