Common truss connections

The main connections in trusses are factory fixed nail plates. Nevertheless, many elements in the roof assembly still require fixing on-site.

AS 4440 determines methods for common connections. However, if skew nails, nail plates or metal strapping are used, wind load classifications must determine the connection. In high wind areas (N4, C2, C3) the connections tend to be upgraded from nails to nail plates, and from nail plates to straps.
