Available across the DeltaTrim, DeltaTrimTrim, DeltaTrimCorro, DeltaOrb and DeltaCorroCorro product ranges, DeltaMax is a steel substrate that provides greater corrosion resistance and a longer working life in demanding environmental conditions.

DeltaMax is suited to corrosive marine environments affected by salt  e.g. Surf Clubs, patios at the seaside or near a canal, swimming pools.

A 275 gram protective coating on the steel is nearly double that of competing products, creating a longer-lasting product. A self-healing coating protects the steel against light scratching and superficial damage.

DeltaMax is available with an extended warranty in comparison to other insulated panel products on the market.

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


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


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.


Bend test:
