MAX paint finish is a steel substrate product offering high corrosion resistance and is available for use across our range of insulated roofing and walling panels. It is ideally suited for use in marine environments affected by salt e.g. saltwater swimming pools, properties located in seaside areas or near canal waterways.



The standard manufacturer's warranty on the MAX paint finish is 20 years, with site specific warranties of up to 25 years available.
The 275 gram MAX protective coating on the steel is nearly double that of competing products. It is made up of 240 grams MagnaFlow and 35 grams of Pretreatment.
The MAX corrosion resistant steel substrate is available for the following insulated roofing and walling panel profiles:

Tested under New Zealand's most demanding environmental conditions and ready for the harsh Australian landscape.
Results from lab tests are backed up with ongoing testing through out New Zealand providing real world testing in demanding industrial and marine environments.

Salt spray
Meets the requirements of AS/NZS2728:2013 Sections 2.8 and 2.10.

Humidity resistance
Meets the requirements of AS/NZS2728:2013 Sections 2.8 and 2.9.

QUV resistance (durability of coating system)
Meets the requirements of AS/NZS2728:2013 Section 2.8 and Table 2.4.

Bend test
AS/NZS2728:2013 section 2.6.1 and Appendix F. No loss of adhesion or paint cracking when bent around a diameter equal to five times the thickness of the sheet.

Impact resistance
AS/NZS2728:2013 Table 2.2 and Appendix E. No loss of paint adhesion after a test piece is struck on the reverse side with a specified force, in line with the test methodology described in Appendix E.

Scratch resistance
Good scratch resistance. Testing includes needle scratch test – no marking of paint surface when a needle with a 2kg weight attached is drawn across. ASTM D5178-13.

Heat resistance
Suitable for continuous service up to 100ºC. Continuous service at higher temperatures may cause some colour change and damage to the paint film.
