Available across the DeltaTrim, 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.
