Mending Plates

A mending plate is the flat steel reinforcement plate used to repair, reinforce, or join timber sections in a straight line - the simplest possible fixing for a cracked beam, a weakened joist, a split board end, or a glued joint that needs additional mechanical support. At the DIY Hardware Store, our mending plates cover the zinc-plated straight plates used in furniture repair, general joinery, and light structural timber reinforcement.

Where a corner brace reinforces a right-angle joint, a mending plate reinforces a straight in-line connection - it's fixed flat across both pieces of timber with screws, bridging the joint or crack and providing mechanical continuity across the repair. They're used to repair split furniture rails and legs, to reinforce weakened shelf supports, to join short timber sections end-to-end in framing work, and as a general-purpose repair plate wherever a simple flat metal bridge is needed across a weak point in timber.

Available in multiple sizes from small furniture repair plates to longer structural reinforcement versions at the DIY Hardware Store, in zinc-plated steel for general internal use.
