True Oak® Corrugate


Roofing Industries introduces a New Zealand first – True Oak® Corrugate, the first major advance in metal corrugated roofing for over 70 years. True Oak® is a return to the original, deeper, rounder sinusoidal wave corrugate profile.

Strikingly different from traditional shallow corrugated profiles, True Oak® adds style and charm to any roofline. The distinctive shadowlines and deeper curves transform the performance of corrugated roofing.
