Types of corrugated roofing

  • Corrugated galvanized iron describes the original product that was wrought iron plate coated with zinc and then roll formed into corrugated sheets. This product is still used in some areas.
  • Galvanized steel. Still manufactured but mostly used for heritage products.
  • Zinc 55% / aluminum 43% / silicon 1.6% coated steel. Sold under various trade names. i.e. "Zincalume". Often left in the zinc finish, but more widely with factory coated colors (colorbond).
  • Metal tile sheets made of high quality zinc coated roofing steel and polyester coated on top
  • Stainless steel. Available for harsh conditions, rollformed and fixed similar to corrugated steel profiles.
  • Aluminum - One of the longest lasting metals, but somewhat expensive. Aluminum roofs are lightweight, corrosion-resistant, and have high reflectivity, which may help increase a building's energy efficiency.
  • Copper - Usually used for flashing or very small sections like covered entryways.
  • Stone coated steel - Panels made from zinc/aluminum coated steel with acrylic chip.
  • IBR or Inverted Box Rib is a low-cost corrugated square-fluted iron roofing used mainly in the South African market.

Installing metal roof battens

Metal battens are relatively easy to install, starting with the truss apex battens. Hit some guide nails into the trusses to sit the battens on so they end up 100mm (4") from the truss apex. Using a good 18-24 volt cordless drill, attach the batten to the trusses with roofing screws. Now install the end batten at the overhang of the trusses, 50mm (2") from the ends. Install the inside battens at maximum 900mm (36") centres as evenly as possible up the truss top chord.
