Pryda Span Trusses
Pryda Span trusses have metal diagonal webs for light weight and economy. They are ideal for shallower trusses where there is more clearance room to accommodate the plumbing than with timber webs and for trusses where the chord design has some reserve capacity, as is often the case. In some instances, a few diagonal metal webs may have to be replaced by timber webs in these trusses, as load or geometry considerations dictate. Webs may be on both faces of the truss or just on alternate faces, and in the latter case this allows for the webs to overlap.
Pryda Span trusses are referenced as PS25, PS30, and PS4O, where “PS” means Pryda Span, and “30” is the nominal overall depth (cm). The overall depths are nominally 250, 300 and 400 mm deep. The actual depth dimensions are in nominal size steps according to the metal web used and if required, the specific depth should be obtained from the Pryda licensed fabricator.
