Wind TC2 to AS1170.2
Full range of design charts for TC3, with variable frame spacing
For manufacturers one use of the charts is to plot sales history frequency of various size sheds on the charts and use to determine an optimum section for a range of sheds. It is not economical to keep changing size of components, just because of minimum weight structure: doing so does not provide minimum cost structure. Set up times for roll forming, material change overs from C150 to C200 or variations in material thickness all add cost.
