History
The first light frame trusses were built on site using nailed plywood gusset plates. These trusses offered acceptable spans but demanded considerable time to build. In the 1950's the metal connector plate transformed the truss industry by allowing efficient prefabrication of short and long span trusses. Originally developed in the United States, the truss plate is now the connector used in light frame trusses.  The popularity of this system grew rapidly since trusses could be prefabricated using highly efficient production techniques and machinery. Today economy, fast delivery and simplified erection procedures have made wood trusses competitive in many roof and floor applications in both long and short spans.
