ZINCALUME® steel with Activate® technology is an aluminium / zinc / magnesium alloy coated steel. Activate® technology is designed to slow the rate of corrosion resulting in more effective, longer-lasting protection.

ZINCALUME® steel is typically formed or fabricated into roofing and walling, garage doors, structural sections, or other general manufactured articles.

It was developed in 1976 and over the years has been refined to meet the needs of Australian customers. In 2013, ZINCALUME® steel with Activate® technology was introduced after almost two decades of testing and development facilitated by our Research and Innovation team at Port Kembla, New South Wales.

ZINCALUME® steel conforms to relevant Australian Standards AS/NZS 1365:1996 (R2016) and AS 1397:2021 and is backed by BlueScope warranties1 for peace of mind.

For thickness range, coating class, steel grade and other technical information please download the ZINCALUME® steel datasheet.
