However, some features are standard to all fire doors, including fire-rated hinges, heat-sensitive intumescent seals, and closing mechanisms. Here, Roland Etheridge, Category Manager at IronmongeryDirect, looks at some of the key fire-rated solutions from its online catalogue of over 18,000 products that help installers comply with the latest regulations. Hinges Fire doors must have a minimum of three CE or UKCA Marked BS EN 1935 fire-rated hinges, with all screws fitted and installed with intumescent pads. The hinges should be free of metal fragments and oil leakage, as these are signs of extreme wear. If the hinges squeak, they must be replaced immediately. IronmongeryDirect has a wide choice of fire-rated hinges in a range of sizes and finishes, including Stainless Steel, Polished and Satin Chrome, and Antique Brass. The line-up includes its exclusive Altro Twin Ball Bearing Fire Door Hinges, which are CE Marked and compliant with BS EN Grade 13, available either as a pair or pack of three. Intumescent Seals Intumescent seals are crucial components for ensuring fire doors work as expected in the event of a fire and should be fitted to the door and frame. When exposed to heat, this material expands to fill the small gaps around the door and other components to trap fire and smoke. Intumescent pads must also be fitted under CE-marked fire door hinge leaves on both the frame and door. IronmongeryDirect stocks a range of intumescent pad packs that are suitable for 30- or 60-minute fire doors in a choice of sizes, which are fully tested to BS 476 Pt 20:22 and Pt 31.1 (cold smoke leakage) as well as CERTIFIRE certified. Locks and Handles Locks and handles must be selected carefully to ensure compliance with regulations. The lock must be CERTIFIRE approved and match the fire rating of the door set, as well as being sturdy enough to withstand the level of use. The door handle also needs to meet accessibility requirements, so that anyone using the building can open the door. For example, the Touchpoint 19mm Return to Lever Door Handle is made from 304-grade stainless steel for low maintenance longevity. The design of the crank is also compliant with BS 8300 (Equality Act), making it ideal for public environments. Door Closers and Hold Open Devices Door closers should comply with BS EN 1154 Controlled Door Closing Devices or BS EN 1155 for electromagnetic closers and fire door holders. They must be CE Marked and validated by a Declaration of Performance (DoP) from the manufacturer.
