The Role of Ironmongery in Enhancing Fire Door Safety

Ironmongery, often considered the backbone of door installations, plays a pivotal role in the safety and functionality of fire doors. Fire doors, designed to prevent the spread of fire and smoke, rely heavily on the quality and installation of their ironmongery components to function effectively. Let's delve deeper into the significance of ironmongery in fire door safety.

Essential Components and Their Functions

Ironmongery encompasses a wide range of metal fittings, including hinges, handles, locks, and closers. Each of these components has a specific role

Fire Door Parts Include:


These ensure the door remains securely attached to its frame. For fire doors, it's crucial that hinges are robust and can withstand the intense heat, preventing the door from collapsing. 

Handles and Locks

While primarily used for accessibility, in the context of fire doors, they must be made of materials that won't easily melt or warp. This ensures that doors remain accessible for evacuation during a fire.

Door Closers

These devices ensure that the door closes automatically after being opened. In the event of a fire, this automatic closing prevents the spread of flames and smoke to other parts of the building.
