The Natural Choice
The hues of nature have determined our response to colour. Red based tones remind us of sunshine, earth and fire – so we think of them as warm and inviting. Blues are considered cool and refreshing, greens are restful and reminiscent of leafy glades and luxuriant growth. Sand spans the colours of the seaside to the richer desert hues. There is also the comfort of the stone colours that offer security and strength.
To our personal preference we add the ingredients of environment, situation and interaction of design when making a new roof colour choice. A Colorsteel® Endura™ prepainted steel roof reflects these hues of nature.
To the steel core of each Colorsteel® Endura™ prepainted steel sheet, a remarkable coating called Zincalume® has been applied. The zinc and aluminium in this Zincalume® steel coating combine together 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® Endura™ prepainted steel products can be used in all moderate to severe environmental conditions within New Zealand. For those very exposed coastal conditions or in very severe industrial or geothermal areas, please seek advice from a Farnsworth Roofing representative.
Limitations Of Use
Colorsteel® Endura™ products are not recommended for use in very severe environments, i.e. within 100m of breaking surf or corrosive industrial emissions. (Very severe marine environments are characterised by heavy salt deposits and the almost constant smell of salt spray in the air.) Refer to New Zealand Steel’s Environmental Categories Guide for further information on the definition of corrosive environments. (For very severe environments, Colorsteel® Maxx™ material may be suitable). Before using Colorsteel® Endura™ products near sources of industrial pollution or in geothermal areas, consult the Project Manager at Farnsworth Roofing Ltd.
Colorsteel® Endura™ products should not be used in the following applications:
Embedded in concrete
In contact with permanently wet materials
In contact with soil, bark or similar
As concrete formwork
In intensive animal shelters
Copper or brass pipes must not be allowed to discharge onto Colorsteel® prepainted steel products or be allowed to come into contact with them. The use of other materials in proximity to Colorsteel® prepainted steel products must be in accordance with the New Zealand Steel Specifiers and Builders Guide. Mixing of brands of prepainted material on the same building is no recommenced by New Zealand Steel Limited.
The reaction between Zincalume® steel and lead flashings will degrade the Zincalume® steel material. Soft zinc or aluminium flashings should be used. Marking with lead pencils is not advised, and sealing washers should be low carbon non-conducting. Refer to the New Steel Installers Guide under the ‘Marking, Cutting and Drilling’ section.
