With new game changing ACTIVATE™ technology, COLORSTEEL MAXAM® is made with corrosion resistance and longevity in mind. A new roofing solution suitable for most NZ environmental conditions. Suitable whether your project is on the coast, inland, in a geothermal area, or in an industrial environment. No guessing, no confusion, no wrong choices. The only exception being extremely severe or aggressive environments where COLORSTEEL ALTIMATE® may be more suitable.  

Whilst COLORSTEEL MAXAM® is suitable for use in most New Zealand environmental conditions, the location of your project and its environmental surroundings can influence the warranty you receive.

Your property’s environmental category is a classification of the harshness or severity of the environment it’s in, which affects the length of your warranty. We categorise this, by describing the surrounding environment as:

  • Mild
  • Moderate

  • Severe

  • Very severe

  • Extremely severe

A number of factors can contribute to the environmental category, but the most significant consideration is how close the property is to the coast.

The following is a guide to which products are appropriate for which environmental category. Please seek advice from your COLORSTEEL® Supplier or contact us directly, for the warranties available for your location or product selection advice.

Please note: This is a guide only. Each warranty will be assessed on a case by case basis. To learn more check out the Environmental Categories & Warranty Guide. To ensure your COLORSTEEL® warranty remains valid, you need to ensure you maintain the product according to the warranty requirements. Check out our tips for caring for COLORSTEEL®.

Special Environments

In New Zealand, there are areas where local conditions create an increased likelihood of corrosion.
Special consideration should be given when selecting products and materials in these areas. 

Geothermal Areas

Geothermal activity creates a corrosive environment. Variations in natural activity, the draw-off from steam bores, as well as the effects of weather conditions make these high-risk areas hard to define. If you think you might live in a geothermal area, get in touch with COLORSTEEL®.

West Coast of the South Island

Smoke from coal burning fires may cause high concentrations of sulphur dioxide in the air. The sulphur dioxide, combined with the region’s high rainfall creates an aggressive environment. If you’re unsure about the category of your environment, get in touch with COLORSTEEL®.

Other special environments: Internal environments & Industrial environments 

To learn more about special environments see the Environmental Categories & Warranty Guide, speak to your COLORSTEEL® supplier or contact COLORSTEEL® to confirm the right solution for your environment. Download the COLORSTEEL® full warranty terms and conditions.
