From 1 October 2013, COLORBOND® steel products – including COLORBOND® Ultra steel, COLORBOND® Metallic steel and Coolmax® steel – will have maximum warranty periods of “up to 36 years” when used in certain roofing applications.*

This maximum warranty period represents an increase of “up to six years” over the maximum warranty period offered for original COLORBOND® steel.

The warranty periods applicable for architectural roofing panels using new COLORBOND® steel, for example, have increased from “up to 15 years” to “up to 36 years”.*

BlueScope’s confidence in the durability of new COLORBOND® steel is the result of its improved resistance to corrosion compared with original COLORBOND® steel.

Original COLORBOND® steel substrate was protected by a zinc and aluminium metal coating under the painted surface. New COLORBOND® steel’s substrate is protected by a patented coating with Activate® technology that features the addition of two magnesium compounds into the zinc and aluminium alloy.

The strategically positioned magnesium causes aluminium in the metal coating to more actively protect areas of the base steel following exposure from cutting, drilling or wear.

New COLORBOND® steel’s improved corrosion durability has been verified through extensive accelerated and in-field testing.

BlueScope has invested almost 20 years and $100 million of research and development in Activate® technology, including extensive testing in harsh Australian conditions.

New COLORBOND® steel’s improved corrosion performance compared to original COLORBOND® steel also means BlueScope can explore the possibility of offering products in new open and unwashed applications such as solar shades, and solar cell and architectural panels.

The COLORBOND® steel warranty gives the peace of mind of local technical support, and because COLORBOND® steel meets the deemed-to-satisfy performance requirements of the National Construction Code, users can avoid related compliance risks simply by specifying COLORBOND® steel.
