Therefore, the minimum allowable pitch for this roof profile is 2.0. Maximum roof lengths are shown in Table 4 and Figure 4. m = 250mmw' = 206mmD = 32.8mm D/2 = 16.4mmw = 201mmh ol =16.9 D m = 12.7 Area = 2420 mm 2 Figure 3DeltaTrim DPP1150 Roof Sheeting Table 3 - DeltaTrim DPP1150 roofing profile variables used for calculations mDh ol w'w'/D > 2.5?Use Eqn.d mwa' D1 or D2?(0.75*h ol ) 250mm32.8mm16.9mm206mm12.2D212.7mm201mm2420mm 2 Table 4 - DeltaTrim DPP1150 Maximum Roof Lengths for Rainfall IntensitiesMaximum Roof Length (m)* 100 I 5ARI Pitch Pitch Pitch Pitch Pitch Pitch(mm/h)23457.510 100126146164180214244 1508498109120143163 20063738290107122 250505966728698 300424955607181 350364247516170 400323741455461 450283336404854 500252933364349 *The designer and installer must provide allowances for thermal expansion according to AS1562.1:2018 and other relevant design codes.Page 6 of 10"
