Fire doors are an essential component of any building’s safety system. They are designed to prevent the spread of fire and smoke, allowing occupants to evacuate safely. Fire door hinges play a critical role in the proper functioning of fire doors. This article will discuss the types and materials of fire door hinges.

Types of Fire Door Hinges

There are two main types of fire door hinges: concealed hinges and surface-mounted hinges.

2. Surface-mounted hinges are visible on the surface of the door and frame. They are available in a range of finishes and are suitable for doors with a weight of up to 160kg.

Materials of Fire Door Hinges

Fire door hinges are typically made from steel or stainless steel.

1. Steel hinges are the most common and cost-effective option. They are suitable for most fire doors and are available in a range of finishes, including brass, chrome, and satin nickel.
