Steel Strong Butt Hinges

For heavy internal and external doors, fire doors, and commercial applications where a standard butt hinge would be undersized for the door weight or frequency of use, a strong butt hinge - also known as a broad butt hinge - provides the increased leaf width and material thickness that delivers genuine structural integrity at the hanging point. At the DIY Hardware Store, our steel strong butt hinges cover the broad butt and standard strong formats used in heavy-duty domestic and commercial door hanging.

Strong butt hinges differ from standard hinges in having a wider leaf (the broad butt format) or a heavier gauge steel construction, providing more screw fixing positions per leaf and a larger bearing area that distributes the door weight across a greater contact area on both door and frame. This reduces the stress at each individual screw fixing, prevents the hinge from working loose under repeated use, and gives the door a solid, quality feel in operation.

Available in steel at the DIY Hardware Store in 75mm and 100mm sizes, sold in pairs for complete door installation, in self-colour and zinc-plated finishes.
