Most Australian garden shed manufacturers use COLORBOND® steel.
However, there are garden sheds available that use imported repainted steel and therefore don't necessarily deliver the same performance levels. To guarantee you are getting genuine COLORBOND® steel manufactured in Australia, for Australian conditions, look for the 'branding', on the underside of the sheeting. See our page on How To identify Genuine Product to see an image of the branding messages on COLORBOND® steel.
The importance of looking for the brand was highlighted during recent market research undertaken by BlueScope Steel. Some garden sheds where made using imported prepainted steel so BlueScope Steel decided to have these products tested to see how they compared with COLORBOND® steel.
Research and Technical services people noticed that the primer was relatively thin. Additionally the paint was on a very thin zinc coated steel base. By comparison, COLORBOND® steel used in garden sheds has a ZINCALUME® steel base, with a zinc/aluminium alloy coating that is about 50% thicker. This means in most applications the COLORBOND® steel would have a longer service life. The other material would typically deteriorate to show red rust much sooner.
One interesting point was that the retailer of the sheds kept calling the product a "Colourbond" shed. This may mislead consumers into thinking the shed is made from COLORBOND® steel, made by BlueScope Steel. Therefore you should always look for the brand to ensure you are getting genuine COLORBOND® steel - manufactured by BlueScope Steel, in Australia, for Australian conditions.
