Developed to optimise the designer’s needs for efficiency, aesthetics and structural performance
Load/span figures
These tables are based on a combined imposed load of 1.50kN/m2, a construction line load of 1.5kN/m and a deflection limit of L/200. The factor of safety used is 1.5 for live load and 1.35 for dead load. Where actual design loads exceed these, the spans must be reduced. Subject to satisfactory fixings, the decks will resist wind uplift to at least 1.50kN/m2 to a deflection limit of L/150.
Full load/span tables are available to download below
Maximum cantilevers assume 0.9kN point load on the end, with the adjacent span being the single span as shown in the table. The end of the cantilever must be stiffened with an angle flashing.
Self curving
Self curving can induce stress marking in the sheet. The radius limits suggested in the tables reduce the visible effect of this; however some perceptible distortion may occur.
Factory curving
RoofDek D35 and D46 can be supplied crimp curved down to 400mm radius. The maximum crimped curve sheet length is 5m with a minimum straight 200mm lead in and 200mm lead out leg.
Aluminium and other material specificiations not shown here are available subject to minimum order quantity. Colorcoat HPS200 Ultra® is available single or double-sided on selected products and gauges. Please contact our estimating department for availability.
Load/spans are calculated to Eurocodes 3 and 9, however a fixings check is also required.
D32S and D35 are assumed to bear onto a 65mm purlin flange, D46 and D60 onto 100mm min. flange steel beam.
*(F0.40) – Factory crimp curving available to 0.40m radius.
