These spacings may be reduced by the serviceability and strength wind conditions for the particular project under consideration.

Testing was conducted in accordance with AS 1562.1 - 1992, Design and Installation of Sheet Roof and Wall Cladding, and AS 4040.2 - 1992, Resistance to Wind Pressure for Non-cyclone Regions. The table for wind pressure capacities provides pressure versus span data for serviceability and strength limit state design. Serviceability Limit State is based on a deflection limit of: (span/120) + (P/30), where P is the maximum fastener pitch. The pressure capacities for Strength Limit State have been determined by testing the cladding to failure (ultimate capacity). These pressures are applicable when the cladding is fixed to a minimum of 1.0 mm material. To obtain the design capacity of sheeting, a capacity reduction factor should be applied (ø = 0.9).
