FAQs

COLORBOND® Coolmax® steel is available in three introductory sizes: 0.42 x 940mm and 0.48 x 940mm for roofing, and 0.55 x 1200mm for accessories.

COLORBOND® Coolmax® steel is available in three sizes. The two roofing sizes are available on two weeks production lead time plus transit times. The accessory or flashing size is available on three weeks production lead time plus transit times. Please see our supplier list.

Yes. As with other bright and light-coloured materials, consideration should be given to visual amenity, particularly in hilly terrain where the roof can be viewed by neighbouring properties to the south and above.

No, generally not. The steel infill panels, posts and rails are the same colour on both sides. You can add some colour variety by 'mix and matching' sheets, posts, rails, lattice and caps of different colours along the fenceline, see our fencing colours page to help with your colour choice. Please note that you cannot place infill sheets of different colours back to back - the posts and rails are not designed for this. The only way to achieve a different colour on one side of the fence is to paint it. Overpainting will, however, result in a surface which is not as durable as the original oven-baked COLORBOND® steel paint finish. Painting the fence will also void any warranty on the infill sheets. For more information on how to paint products manufactured from COLORBOND® steel, visit our Technical Bulletins page and read TB-2 Overpainting and Restoration of COLORBOND® Prepainted Steel Sheet. However, if you have a substantial development proposal that might involve a large quantity then please contact us.

Standard heights for COLORBOND® steel are 1.5m and 1.8m. These are readily available. If you require a different height, this can generally be organised by your supplier - however you may need to wait longer and there may be extra charges applicable.

The cooling energy savings associated with COLORBOND® Coolmax® steel have been quantified in our own BlueScope Steel building study. This involved comparing the relative running costs of three identical insulated buildings, the only difference being the type of roofing material used. The results have been used as a guide to possible savings for other buildings. This is further supported by information from reputable sources in the public domain, see our Calculator and Case Study.

All light products have a greater tendency to show dirt than darker colours. Fortunately all COLORBOND® steel has excellent resistance to dirt retention, so regular washing from the rain is all that is usually required to keep your roof looking great.
