I got my steel samples!! I a lot more than I hoped for which is great.

With the help of colourbond steel centre, I've listed and given a brief description of each colour. But first, here's some basic need to know things about colourbond steel:
Colourbond steel has a low thermal mass, which mean it cools down fast was the sun is off it. Lightweight steel can help minimise the amount of heat radiation into the home.

Surfmist -
One of the most popular colours on the steel palette and is also one of the most thermally efficient. Lighter colours are especially good at radiating less heat during summer.
