Product Information

However, it is common for reputable fire door installers to use a grade 13 hinge when installing fire doors. Grade 13 hinges are able to support more door weight than a grade 11 hinge and are generally more resilient. The hinges are often tested alongside the doors they are recommended for use with and are most commonly made of steel, although brass hinge use is popular too. Bought them in case I needed them. Glad I did. Easy to fit and use. Would have been lost without them. Fire doors tend to use a minimum of three hinges rather than two, as seen on domestic and non-fire doors. This is not only to carry the weight of the substantially constructed door but also helps to prevent the door from bowing in the event of a fire. Additionally, the ongoing wear on the hinges from bearing the weight of the door and opening and closing cycles can be exacerbated by the use of door-closing devices. It is therefore good practice when selecting the correct hinge grade when using a self-closing mechanism to opt for a hinge that is capable of carrying up to 20% more than the actual door weight.

Complimentary products The hinges used to attach the fire door to the surrounding frame must be rated adequately for purpose. The standard used to rate hinges is BS EN 1935:2002 Building hardware. Single-axis hinges. Requirements and test methods.(https://shop.bsigroup.com/ProductDetail/?pid=000000000030118674). Up to 2002, BS 7352 indicated that a grade 8 hinge would be sufficient to be fitted to a fire door. However, BS 1935 replaced that guidance and the more recent standard requires a grade 11 hinge as a minimum for new fire door installations. If a fire door was installed in 2001 and has hinges of grade 8 or higher, it remains appropriate for continued use until it is replaced.In part 9, LWF talked about fire doors and the need for third-party accredited door sets and installers. In part 10, we look at fire door components, specifically the hinges. Even the smallest fire door should use a recommended grade 11 hinge, which is a hinge that has been fire tested and can maintain a door up to 80 kg in weight.
