True Oak Corrugate
Description

Roofing Industries introduces a major advance in metal corrugated roofing and cladding. 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.

Key Features
  • Greater span reduces construction costs
  • Strongest residential metal corrugated profile
  • Warranties meet New Zealand's Building Code
  • Installation possible at 4 degree pitch
  • Enhanced water carrying capacity
  • Ability to down-gauge due to profile strength
  • A snug-fitting lapping edge is aesthetically pleasing
Scope of Use
  • Commercial Roofing and Cladding
  • Residential roofing and cladding requiring that classic appeal
  • Reroofing of historic and heritage buildings
  • Roofing of outbuildings
  • Low pitch roofs and verandahs
  • Curved and bullnosed projects

Metal Roof and Wall Cladding materials used to construct the building envelope shall be:

  • In accordance with the durability requirements of NZBC B2 suitable for their end use, location and environment as shown in E2/AS1 Table 20, and;
  • Compatible with adjoining materials as shown in E2/AS1 Table 21 and Table 22; and
  • Meet NZ Metal Roof and Wall Cladding code of practice; and
  • True Oak Corrugate will meet the risk score in E2/AS1 13 - 20 for vertically fixed and also horizontally on a cavity. Over 20 will require specific design.
Limitations on Use

Commercial Design compliance is in accordance with current Roofing Code of Practice v3.0

4° Minimum Roof Pitch Required
Statement of Building Code Compliance

True Oak Corrugate will, if employed in accordance with the supplier's installation and maintenance requirements, assist with meeting the following provisions of the building code:

  • Clause B2 - Durability: Performance B2.3.1(b)
  • Clause E2 - External moisture: Performance E2.3.1, E2.3.2

Selection of the correct grade of material and appropriate surface coating is imperative to ensure True Oak Corrugate performs satisfactorily in the environment it is to be installed, meeting the requirements of The NZ Building Code.

In-Service History

Launched in 2013, True Oak has been installed nationwide on thousands of homes and commercial buildings including historical buildings, public buildings, factories, schools and aged care facilities.
