66. ESTIMATION OF MATERIALS6.16.1 ESTIMATION OF CORRUGAT ED SHEETSFor proper estimation of the sheets, the following points should be considered:• The slope length• The slope (pitch) of the roof• The length of the sheet to be used – 1800mm, 2400mm etc• The end and side lapsIn all designed projects the roof slope will be specified, however therecommended minimum slope is 15 degrees.fig. 6.1Roof slopeSteps to Take When Estimating1.2.3.4.From the roof plan drawing or from physical measurements, the length and width of the roof areobtained as L Rand W Rrespectively. ( Including the horizontal projection of the eaves).From technical data table of page 17, the rafter length is obtained (R ) ALIn the case of multispan roofs, separate these spans and treat them individually.Choose the length of the sheet to use and hence determine the overlaps and net sheet dimensions.32®<strong>PROFILE</strong> 3 MANUAL
