are classified as trafficable when used for maintenance 
purposes. The following recommendations should be 
observed at all times.

• Crawl boards should be used when accessing  
    areas not supported by a structure
Colour Chart - Warranty
Expanded Polystyrene Fire-Retardant Grade (EPS-FR) 
is a thermoplastic that when exposed to high levels of 
sustained heat is subject to changes in its structural 
properties. On extremely hot days with no cooling 
wind, dark colours have been recorded as reaching 
extreme temperatures. The manufacturer of the steel 
recommends the following colours, subject to conditions 
of use, will maintain a temperature under 78.0oC 
dry heat (see clause 9, sub-clause j of our product 
Warranty). Please refer to Clause 12 of the Warranty – 
Roof Products for full details.
• Off White / Surfmist ®
• Gull Grey / Shale Grey TM
• Merino / Paperbark ®
• Mist Green / Paperbark ®
• Smooth Cream / Classic Cream TM
• Hamptons White 
• Zinc
• Birch / Dune ®
• Armour Grey / Windspray
To maintain Warranty cover with dark colours it is 
therefore recommended that a Thermosetting Phenolic 
Composite (TPC) core be used for all colours not listed 
above.
