GALVASPAN® steel is a hot-dipped zinc-coated structural steel for commercial and industrial buildings that is typically rollformed into purlins.
Made with a high-tensile steel substrate and available in Z350 and Z450 coating classes, GALVASPAN® steel is strong, durable and highly corrosion resistant. It is available with a guaranteed minimum yield strength of 450MPa, 500MPa or 550MPa across a range of thicknesses.
GALVASPAN® steel is strong, durable and backed by BlueScope warranties1, providing peace of mind. A 10-year warranty may be available from the date of installation against corrosion to structural failure, when used within the building envelope (not exposed to external environment).
GALVASPAN® steel conforms to the relevant Australian Standards AS/NZS 1365:1996 (R2016) and AS 1397:2021.
For thickness range and coating class2 by steel grade and other technical information please download the relevant GALVASPAN® steel datasheet.
- Warranty subject to exclusions, application, and eligibility criteria. For full terms and conditions and to determine the eligibility of your product for the warranty, please visit the BlueScope warranty website or contact us on 1800 800 789.
- Coating class recommendations for a range of building applications and further selection guidance information is available in BlueScope’s Technical Bulletin 17 ‘Selection guide for zinc-coated steel purlin products’.
Zinc-coated purlins made from GALVASPAN® steel are made with high-tensile steel and a minimum zinc coating of 350g/m2 providing excellent corrosion resistance, durability and long life.
