Setting a new industry benchmark, next generation ZINCALUME® steel meets the growing demands of a changing built environment for durability, resilience and sustainability; giving you the confidence to create for years to come.

Next generation ZINCALUME® steel’s patented Activate™ technology introduces magnesium into the aluminium-zinc alloy coating, improving galvanic protection by activating the aluminium. The result is a tougher protective coating that's more resistant to scratches and scuffs encountered during construction.

The protective coating innovation also increases the product lifespan of next generation ZINCALUME® steel whilst using fewer metal resources. Compared to ZINCALUME® steel AZ150, next generation ZINCALUME® steel AM125 has a smaller environmental footprint^ in all 18 Life Cycle Assessment (LCA) categories assessed.

Over a 17 year period, more than 5,000 panels have been tested in a wide variety of laboratory and ‘real world’ climatic conditions. Additionally 50 building sites, comprising a wide range of applications, as well as 5 purpose built test structures have been tested in the real world, including extreme marine environments. The result is confidence that next generation ZINCALUME® steel is more durable and more resilient.

From its launch in August 2013, roofing applications made from next generation ZINCALUME® steel will be backed by a warranty of up to 36 years, including warranties closer to marine environments.

Next generation ZINCALUME® steel is made only by BlueScope Steel and will be identified by its brand mark, which is printed on the steel. Check for the brand and you can be sure it meets AS1397, and the "deemed to satisfy" requirements of the Building Code of Australia (BCA) for roofing and walling applications. Specify correctly by name - ZINCALUME® steel AM125.
