Corrugated steel was an idea first thought of back in 1843 in England. They discovered that by corrugating a thin sheet of iron, it made for a much stronger yet still lightweight building material.
For cosmetic reasons, people would paint the corrugated iron but this was expensive and had to be done frequently in order to keep it looking good.
Luckily a product called Colorbond was invented. They figured out a way to bond paint to galvanised steel. It comes in an array of colour choices and is also thermally efficient.
Colorbond steel is long lasting and 100% recyclable leaving a smaller footprint on the environment. Not only that but it is resistant to termites, corrosion and also cracking, peeling and chipping. It is also extremely lightweight which makes it very popular in the roofing and other building industries.
After many year of research Zincalume was introduced the the market in the 1970s. It is made up of aluminium, zinc, and silicone. It has proved to be up to four times more durable than galvanised steel. It has been designed to last a lifetime and to stand up to all the harsh elements Australia has to offer.
Keeping up with technology Zincalume has an activated aluminum coating that makes it more durable and resistant to scratches when erecting.
