Finally the truss calculator will compute the best dimensional method to connect the pieces of the truss with steel joints and a bridge. There is a misconception that spacing trusses every 16 on center is better because it will be strong than the average 2. This document aims to apply to aussteel steel wall frames and trusses within the subsequent general limitations. The truss designer is only responsible for individual trusses not the roof system.

The trusses should be a little longer than the exact width to allow for overhang and you will need sufficient trusses to mount across the length. Although the standard spacing of roof trusses may be the same as that of rafters with 24 inch spacing being a common option the design of a truss may allow for the use of a lower grade of lumber than would be required for rafters with comparable spacing and span. Engineers have since determined however that the physical design of a post frame building will allow for standard spacing as great as 12 feet from the center when using high quality metal connector plates and lumber. While this can be true it is not always accurate unless in some high stress.
