How to choose the fire rated door hardware?

Fire has always been a hidden danger in our lives, which is why many public places and homes are now equipped with stainless steel fire doors. This way, in the event of a fire, our lives can be better protected. Here we take a look at the features of metal fire doors and a guide to choosing fire door hardware.

To ensure the quality of stainless steel fire doors, how to choose hardware is also an important part of the process. As fire doors are specifically designed for fire protection, their fittings are unlikely to burn naturally and instantly, so the choice of fire door hardware must be rigorous. D and D HARDWARE is equipped with a range of certified hardware to meet a variety of design requirements. All hardware is available in a wide range of surface finish options.

1.  The fire rated door hinge

Fire rated doors are generally thicker so that they can perform as fire rated as they should, and to ensure smooth opening and closing, they need to be hinged to the door frame. If the fire rated hinges themselves are not strong enough to resist fire, they are bound to become short door of the whole door. It is therefore essential that all labelled door hinges are made of high quality steel and meet sufficient specifications to avoid deformation at high temperatures.

What are the general standards for fire rated door hinges?

Hinges selection of based on the following factors:

●Door weight

●Usage frequency

●Door dimension

●Ball bearing hinges are mandatory requirements for all fire rated door openings.

D&D produces the highest quality of stainless steel fire rated hinges，tested to international industry standards（European Standards& American Standards）, including BS EN, CE, UL, ANSI and BHMA, Suitable for education, healthcare, hospitality, residential and commercial applications.

For example, BS EN 1935 uses 8-bit coding system to classify door furniture. Each number contains different hierarchical requirements: category of use; durability, test door mass, fire resistance (grade 1 is Suitable for fire/smoke resistant door assemblies subject to satisfactory assessment of the contribution of the single-axis hinge to the fire resistance of the specified fire/smoke door assemblies.); Security and door high grade.

2.   The fire rated mortise locks

3.  The door closer

The function of the fire rated door closer is that when the fire door is opened, the door closer will automatically activate and close the fire door so that it can be closed, enabling the fire door to effectively prevent the spread of fire and smoke.

The first thing to look for when choosing a fire door closer is whether the closer meets the requirements of international standards such as CE/UL certification. Secondly, the metal door closer should be selected according to the weight of the door, the width of the door, the frequency of opening the door and the environment and requirements of the use. In general, the weight and width of the door are the main factors in choosing the type of door closer. If the door weighs less, choose a model with less strength, and vice versa. And the frequency of opening is closely related to the quality of the product. For frequent use, choose a door max with good sealing properties and a long service life.

Width of door max (kg):40-60kg

Width of door max (kg):60-80kg

Width of door max (kg):80-120kg

P.S: Double doors with two door closers shall be equipped with one door selector.
