Description
Colorbond and Zincalume are BlueScope's flagship coated steel products, featuring Activate® technology for enhanced corrosion resistance. Available in Base Metal Thickness (BMT) from 0.42mm to 0.60mm, with yield strengths of G300 (300 MPa) or G550 (550 MPa). Colorbond adds a five-layer paint system with Thermatech® solar reflectance technology, while Zincalume features the bare metallic coating for architectural applications.
