COATING AND COMPLIANCE WITH AS/NZS 2728 (CORROSION RESISTANCE)

An independent laboratory was employed to ensure KiwiColour complies with the AS/NZS 2728:2013 performance requirements. The laboratory had the following findings: “KiwiColour Vitor+ and Zenex+ products are manufactured overseas** and distributed in New Zealand by Kiwi Steel. Kiwi Steel engaged an independent laboratory to assess KiwiColour Vitor+ and Zenex+ products against the corrosion resistance performance requirements of AS/NZS 2728:2013.”

“In accordance to AS/NZS 2728:2013 Product Type 4 is suggested for use in corrosive environments
up to and including ISO 9223 Category 4‘High’ (coastal/low salinity). Most populated areas of New
Zealand fall within this category and only off-shore installations, geothermal areas, specific industrial environments, direct beach fronts and beach fronts with high wind and surf exceed this corrosivity category in New Zealand.”

“From the results available KiwiColour Vitor+ and Zenex+ products conform to the performance requirements of Product Type 4 in all aspects of salt spray performance and humidity resistance. Other product specific properties such as coating thickness, gloss and cross hatch adhesion also fall within the requirements of Product Type 4 (Gloss Category 2).”
All KiwiColour materials are available on Masterspec. ** Steel manufactured overseas and roll-formed in New Zealand.

LEAD FREE

To ensure compliance with international and local regulations regarding chemical composition of our KiwiColour pre-painted steel, the full range of KiwiColour paint systems were tested for lead content by SGS, one of the world’s largest internationally recognized independent inspection, verification, testing and certification companies. These test results showed no lead content present in any of our KiwiColour paints.

Painting

ZINCALUME® coated steel is readily paintable using good quality primers and water-based acrylic topcoats. Paint manufacturers’ instructions should be followed.
