The ideal solution for rugged coastlines. Designed specifically for New Zealand’s more extreme conditions, Colorsteel® Maxx® will stand up to higher atmospheric salt concentrations. Appropriate for roofing, cladding, gutters, downpipes, and fences.

A Zincalume® alloy coating is applied to the steel of each Colorsteel® Maxx® prepainted steel sheet. The zinc and aluminium in the Zincalume® steel coating combine to provide both stable corrosion protection overall and galvanic protection on cut edges. In conjunction with the primer and top paint coats, this means the investment in your new roof will be assured for many years to come.

Colorsteel® Maxx® prepainted steel is made touch to withstand harsh New Zealand conditions. One of the most demanding of building environments is the rugged coastline. High concentrations of salt in the atmosphere challenge all but the toughest building materials. Colorsteel® Maxx® prepainted steel has been specifically developed for buildings erected 100m from surf beaches on the West Coast.


*Ideal for severe to very severe environments (determined by your property’s proximity to the coast, geothermal areas and industrial environments)
*Corrosion resistant primer and baked-on finish to withstand tough environments
*Base metal thickness is typically 0.40mm or 0.55mm
*Available in a range Colorsteel colours

A moderate environment is characterised by:
*Little or no salt deposits
*The occasional smell of salt in the air
*Typically starts 500-1000 metres from breaking surf such as is found on exposed coasts, or in the immediate vicinity of calm salt water such as estuaries



A severe environment is characterised by:
*Little salt deposits
*A frequent smell of salt in the air
*Typically starts 100-500 metres from breaking surf such as is found on exposed coasts
*In the immediate vicinity of large expanses of calm salt water such as harbour foreshores



A very severe environment (which starts 25m from the high water mark on the east coast and 50m on the west coast) is characterised by:
*Heavy salt deposits
*The almost constant smell of salt spray in the air
*Close to breaking surf such as is found on exposed coasts


These environments may be extended inland by prevailing winds and local conditions.
