The Difference Between a Colorbond Steel Opening Louvre Roof and an Aluminium Opening Louvre Roof.

Patio Roofs


Colorbond was first introduced in Australia in 1966.  It is a highly popular product in the building sector for its light weight, durability, strength and wide range of colours to fit any design.

Key advantages include:

  • ability to withstand extreme weather conditions;
  • minimal maintenance requirement as the colour is bonded to the steel and does not require repainting;
  • different profiles allowing further customisation in classic or contemporary styles;
  • palette of 22 colours to suit any exterior colour scheme;
  • thermally efficient material utilising Thermatech technology to prevent radiant heat during hot weather as well as cool faster than tiled roofs in the evening.

Colorbond roofing is more expensive than Zincalume; however, the pre-finished colour, low maintenance, and long term performance make it a great choice for the long term.


A blend of aluminium, magnesium, silicon and zinc, Zincalume has been thoroughly tested for its ability to withstand the elements. Zincalume is exceptionally durable, and also environment-friendly as a fully recyclable material.

Unlike older-style corrugated iron roofs that were susceptible to scratching during installation, Zincalume displays reduced risk of damage with advanced corrosion protection mechanisms built into the coating system.

Cost-wise, Zincalume does offer a competitive deal. From an aesthetic perspective, if the natural metal look of Zincalume fits with your vision for your property, you will be very happy with your choice.

Colorbond or Zincalume?

It’s a tough choice and the decision has to be made based on your expectations of the final outcome as well as your budget. Regardless of your choice, your decision to install a metal roof will anyway provide excellent long-term protection from the elements for your home and family. Colorbond will be more expensive initially but the roof will still look great years down the road, and will help you get a better price for your property. Zincalume will continue to retain its natural, somewhat rugged appearance.
