The wall spacings are based on pressures for buildings up to 10m high in Region B, Terrain Category 3 conditions (Vs = 38 m/s and Vu = 60 m/s) using Cpe = 0.65, Cpi = 0.2 and Kl = 2.0. Spacings may be reduced by the Serviceability and Strength Limit States for the particular project under consideration.

Capacity & Load Tables The wind pressure capacities are based on  full scale tests carried out at BlueScope's NATA Registered Testing Laboratory using the direct pressure-testing rig. 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 Pressures for non-cyclonic Regions. The pressure capacities for serviceability are based on a deflection limit of (span/120) + (maximum fastener pitch/30). The pressure capacities for strength have been determined by testing the cladding to failure (ultimate capacity). These pressures are applicable to the cladding being fixed to a minimum of 1.0 mm, G550 steel LYSAGHT CUSTOM ORB® Wind Capacities (kPa) - Limit State Format Base Metal Thickness (mm) Type of Span Fasteners per sheet per support Limit State Span (mm) 600 900 1200 1500 0.42 Single 3 Serviceability 1.91 1.46 1.08 0.77 Strength* 12.00  8.60 5.80 4.65  5 Serviceability 5.39 3.20 2.07 1.19 Strength* 12.00 12.00 10.25 8.20 End 3 Serviceability 1.66 1.40 1.18 1.00 Strength* 9.15 7.55  5.90 4.50  5 Serviceability 6.08 4.27 2.79 1.59 Strength* 12.00  12.00  9.90  7.55  Internal 3 Serviceability 1.91 1.67 1.45 1.23 Strength* 13.35  9.25  7.45  6.00 5 Serviceability 7.00 4.92 3.32 2.21 Strength* 12.00 12.00 12.00 10.80 0.48 Single 3 Serviceability 2.12 1.47 1.03 0.77 Strength* 12.00 9.80 6.55 5.30 5 Serviceability 7.48 3.74 1.56 0.73 Strength* 12.00 12.00 9.65 7.75 End 3 Serviceability 1.92 1.66 1.48 1.35 Strength* 11.70 9.05 6.80 4.95  5 Serviceability 8.00 4.75 2.86 1.97 Strength* 12.00 12.00 12.00 10.60 Internal 3 Serviceability 1.98 1.96 1.84 1.62 Strength* 12.00 10.15 8.50  7.10 5 Serviceability 6.50 5.42 4.34 3.31 Strength* 12.00 12.00 12.00 12.00 LYSAGHT CUSTOM ORB® Wind Capacities (kPa) - Limit State Format Base Metal Thickness (mm) Type of Span Fasteners per sheet per support Limit State Span (mm) 1800 2100 2400 2700 0.42 Single 3 Serviceability 0.49  -  -  - Strength* 4.50  -  -  - 5 Serviceability 0.45  -  -  - Strength* 6.65  -  -  - End 3 Serviceability 0.83 0.67 0.52 0.38 Strength* 3.40 2.70  2.30 2.00 5 Serviceability 1.02 0.65 0.42 0.30 Strength* 5.75  4.50 3.60 3.05 Internal 3 Serviceability 1.03 0.85 0.69 0.56 Strength* 4.85 3.90 3.20 2.70 5 Serviceability 1.49 1.05 0.78 0.59 Strength* 8.85 7.10 5.65 4.50 0.48 Single 3 Serviceability 0.60  -  -  - Strength* 5.10  -  -  - 5 Serviceability 0.57  -  -  - Strength* 7.25   -  -  - End 3 Serviceability 1.19 1.01 0.81 0.60 Strength* 4.10 3.45 3.00 2.65 5 Serviceability 1.39 0.97 0.66 0.44 Strength* 8.00 6.20 5.00 4.25 Internal 3 Serviceability 1.36 1.07 0.82 0.62 Strength* 5.70 4.55 3.60 2.90 5 Serviceability 2.37 1.57 0.95 0.54 Strength* 11.00 8.65 6.75 5.25 * A capacity reduction factor of = 0.9 has been applied to strength capacities.
