Monoclad® Adverse Conditions Stramit Monoclad® cladding will give excellent durability in almost all locations. It is however important to choose the correct coating for each application environment. The table below shows the suitability of coating types for different exposure conditions. suitability of coating type site exposure condition benign moderate severe very severe Zincalume AZ150 ? ? Galvanised Z450 ? Colorbond XRW ? Colorbond XSE N/A N/A ? ? Question marks indicate conditions where durability may be diminished, depending on the particular application. The approximate site exposure conditions in the table above are defined below. distance of site from site exposure condition rough active surf calm, still salt water industrial emmision fossil fuel combustion benign 1000m + 100m + 500m + 500m + moderate 400m-1000m 0-100m 250m-500m 250m-500m severe 100m-400m N/A 100m-250m 100m-250m very severe 0-100m N/A 0-100m 0-100m Maximum Span Chart (mm) Roofs Overhangs bmt (mm) pressure (kPa) internal (end) span combination free edge stiffened edge serviceability strength double span equal spans N1 or Region A (sheltered suburban) 0.42 0.76 1.35 1350 1350 1700 (1400) 150 400 0.48 0.76 1.35 1700 1700 2300 (1900) 200 500 N2 or Region B (sheltered suburban) and Region A (exposed suburban) 0.42 0.78 1.94 1350 1350 1700 (1400) 150 400 0.48 0.78 1.94 1700 1700 2300 (1900) 200 500 N3 or Region A (rural) and Region B (exposed suburban) 0.42 1.18 2.96 1350 1350 1700 (1400) 100 300 0.48 1.18 2.96 1700 1700 2300 (1900) 150 400 Walls N1 or Region A (sheltered suburban) 0.42 0.61 1.04 2700 2850 3000 (2500) 0.48 0.61 1.04 2900 2750 3000 (2500) N2 or Region B (sheltered suburban) and Region A (exposed suburban) 0.42 0.61 1.49 2700 2850 3000 (2500) 0.48 0.61 1.49 2900 2750 3000 (2500) N3 or Region A (rural) and Region B (exposed suburban) 0.42 0.92 2.25 2050 2200 2800 (2300) 0.48 0.92 2.25 2600 2500 3000 (2500) Internal spans must have both end spans 20% shorter.

Foot Traffic Foot traffic limits for Stramit Monoclad® cladding are shown for three alternate foot traffic categories. These are: High Maintenance - for applications with repeated maintenance, particularly where personnel may be unfamiliar with correct procedures for walking on metal roofs. Normal - based on traditional expectations, with moderate maintenance foot traffic using designated foot paths. Controlled - spans that conform to AS 1562 but require minimal careful foot traffic only on the designated foot path. Suggested for use only where occasional aesthetic imperfections from foot traffic are acceptable. bmt (mm) Fasteners per sheet span type high maintenance normal controlled 0.42 4 internal - 1700 2100 equal - 1350 1800 double - 1350 1800 0.48 4 internal 1000 2300 2700 equal 800 1700 2250 double 800 1700 2250 Tables are based on tests to AS1562 and AS4040 parts 0 and 1.
