Abstract

The term 'timber engineering hardware' encompasses a diverse range of metal components made of steel plate, sheet or strip which are used to connect timber members together, usually in conjunction with dowel-type metal fasteners. Timber engineering components have widely replaced traditional carpentry joints due to their ease of use, ready availability and the avoidance of complex machining of timber members. Typical examples of common types include joist hangers, framing anchors, truss clips and wall ties. Mass-produced timber engineering hardware is usually made from pre-galvanised mild steel, from 1mm-3mm thick. However, heavier components are also made for large structures in thicknesses up to 12mm, sometimes in proprietary forms. These thicker components are usually galvanised after manufacture; this has the advantage that the edges, which are otherwise exposed by cutting or drilling, are fully protected. Some manufacturers also supply stainless steel components to order.
