True Oak Deep® Roofing and Cladding System

Product Description

  • True Oak Deep® is a major development in high strength sinusoidal corrugate 
  • Strikingly different to traditional shallow corrugated profiles with no flat areas
  • Smooth rounded and deeper sinusoidal wave profile integrating both form and function — creating distinct shadow lines that can be seen from afar
  • Stronger and deeper than traditional corrugated roofing and cladding
  • Much higher strength underfoot, and far less susceptible to denting by foot traffic
  • A replacement product for similar fibre-cement high rib corrugate — manufactured and supplied to any length
  • Wider sheet coverage, ensuring rapid installation, fewer sheet laps reducing construction costs and the possibility of water ingress
  • Superior water carrying capacity
  • Where building regulations permit, can be installed at a roof pitch as low as 3°
  • True Oak Deep® features an extensive colour and metal substrate selection, providing greater design options and choice
  • Exclusive design protected manufacturing technology
