Lysaght Wallclad® Schematic Physical Properties Mass and Yield BMT (mm) kg/m kg/m2 m2/t ZINCALUME® steel 0.35 2.74 3.60 278 Tolerance Cover: 762mm +/-4mm Length Tolerance:  +0, -10mm Spanning Tables The wall spacings indicated are the maximum recommended for buildings up to 10 m 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. These spacings may be reduced by the Serviceability and Strength wind conditions for the particular project under consideration. Maximum Recommended Support Spacings (mm) Type of Span Thickness (mm) Walls 0.35 Single Span End Span Internal Span Overhang 2100 2400 2400 150 Capacity & Load Tables The wind pressure capacities are based on tests conducted at BlueScope's NATA registered testing laboratory. 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-cyclonic Regions. Serviceability Limit State is based on a deflection limit of: (span/120) + (P/30), where P is the maximum fastener pitch. Strength Limit State capacities 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 (G550). Strength pressures are reduced when fixed to material <1.0 mm. To obtain the design capacity of sheeting, a capacity reduction factor should be applied (ø = 0.9).
