ABSTRACT
A range of steel timber connectors is commercially available. Trussed rafters, which account for a large market, are usually constructed with galvanised steel nail plates (Fig. 4.21). Plates are hydraulically pressed into both sides of the timbers to be connected at the butt joints. Other types of connector include single-and double-sided circular toothed plates fixed with a central bolt, also joist hangers and roof truss clips. Laminated timber beams are usually fixed with purpose-made bolted shoes or plates.
