ABOUT DECRA

THE ORIGINAL INNOVATORS

The invention of our revolutionary steel roofing tiles in New Zealand in 1957 quickly made Decra an industry success story and a trusted manufacturer. Manufactured from clean, pure materials, Decra’s New Zealand-made tiles are manufactured to stringent ISO 9001 standards and exceeds international standards.

Innovation is a cornerstone of Decra’s ethos, with significant investment into research and development resulting in high-performing products and continual new product development.
