A slope of 22Ø (degree) is common for corrugated steel and asbestos roofing sheets. For economic spacing of roof trusses, the cost of truss should be equal to twice the cost of purlins +the cost of roof covering.

WebbAdditionally, the 19.2” on-center spacing is useful when using engineered I-joist/truss rafters with the wider flange. I-truss rafters typically have a gap of 15.7” between parallel flange edges when spaced at 19.2” on-center. A gap that isn’t much different from the 14.5” between trusses at 16” centers. WebbTrusses with N shaped diagonals can span a distance 15-30m. Trusses with N shaped diagonals and secondary members can span a distance 30-50m.
