The fence posts of a fence made from COLORBOND® steel have a different metallic coating underneath the paint to that used in the rest of the fence, which mean they are suitable for concrete immersion. You should not allow the concrete to contact the rails or infill sheets of the fence as this can detrimentally affect the performance of COLORBOND® steel. For the design of concrete footings, we recommend contacting your chosen supplier of fencing made from COLORBOND® steel.

The COLORBOND® steel colours listed on our website show the core colours for our fencing range. Your fencing supplier may offer additional colours, and we recommend speaking with them for the availability of colours that may not be listed on our website.

BlueScope constantly monitors colour and design trends, which informs updates to the COLORBOND® steel range, including the availability of specific colours for fencing applications versus roofing applications. If you find that your desired colour is not listed on our website, we recommend speaking with your fencing supplier as some suppliers may offer an extended COLORBOND® steel fencing colour range.

A possible cause of this discoloration could be the application of touchup paints. Air-dried touchup paint weathers differently to that of oven-baked, prepainted COLORBOND® steel resulting in an irregular fading where these touch up paints have been applied. For more information please refer to Technical Bulletin TB-38 - Effect of touch-up paint.

Generally not. The infill sheets, posts and rails made from COLORBOND® steel are the same colour on both sides. Infill sheets of different colours cannot be placed back-to-back, as 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, however, will result in a surface which is not as durable as the original COLORBOND® steel paint finish. Painting the fence will also void any warranty on the infill sheets, posts and rails. For more information on how to paint products manufactured from COLORBOND® steel we recommend reading our technical bulletin found here.

We recommend speaking to the supplier of your fencing made from COLORBOND® steel to get their installation guides for your style of fence.

No. The coating on the underside of the sheet has different properties which are not designed for prolonged exposure to weather. Roofing profiles are also designed to be used top side up and may leak if installed the wrong way. However, there are roofing profiles available with a coloured finish on both sides of the sheet for specific applications, such as patios and pergolas, where the reverse side of the sheet will be visible. However, colour combinations and styles may be limited and you should confirm availability with your supplier.

Some manufacturers do sell roof sheeting made from COLORBOND® steel with a top coat on both sides. However, colours combinations and styles may be limited and you should confirm availability with your supplier.

The fallout from chimneys and wood fired burners can be unsightly and, if neglected, can damage the surface on which it falls. For information, please refer to Corrosion Technical Bulletin CTB-14 - Exhaust from wood and oil fire burners.

Generally, hail indentations do not typically affect the lifespan of a roof made from COLORBOND® steel. However, potential issues can arise on low-pitched roofs where significant indentations lead to water ponding and dirt accumulation, which may promote corrosion. Similarly, if roof sheet overlaps are deformed enough to lose their anti-capillary effect, water can be drawn into the lap and cause damage. While the impact may cause some loss of the paint topcoat, this is primarily an aesthetic issue and generally does not impact the corrosion performance of the steel. For more information, please refer to Technical Bulletin TB-32 - Impact of hail damage to exterior BlueScope coated steel products.

Neutral cure sealants that conform with the Australian Steel Institute (ASI) Technical Specification TS-001 (non-extended, with a minimum of 90% silicone polymer content) are the most suitable. Any other generic type of sealant considered should possess similar properties to neutral cure sealants that conform with ASI TS001 if long term performance is required. It is most important that only quality neutral cure sealants be used with steel products. Other very common sealants, while being suitable for other materials, liberate by-products during curing which can be corrosive towards the protective coatings applied to steel. These often smell of either vinegar or ammonia. If in doubt, contact Steel Direct. For more information, please refer to Technical Bulletin TB-09 - Sealants for exterior BlueScope coated steel products.

COLORBOND® steel requires minimal maintenance – the wash of natural rain water will help keep it looking good for many years. Areas not regularly washed by rain water, such as wall cladding under eaves, garage doors and the underside of eave gutters, should be hosed down at least every six months and more frequently in coastal areas. In cases where regular hosing does not remove all the dirt we recommend washing COLORBOND® steel with a mild solution of pure soap or non-abrasive dishwashing detergent in warm water. Washing should be done with a sponge, soft cloth or soft bristel nylon brush (no abrasive scourers, steel wool etc) and be performed gently to avoid scuffing. Thoroughly rinse the surface with fresh water immediately after to remove traces of detergent. For more information please refer to Technical Bulletin TB-04- Maintenance of exterior BlueScope coated steel products.

COLORBOND® steel has stringent appearance specifications but to be confident of consistent aesthetic in a roof or wall with a large single plane (i.e. very large roofs and walls) it is best that your builder or roofing installer sources material from a single supplier, and that your supplier has manufactured all roofing and walling material for your project from a single BlueScope paint production run. Your builder or roofing installer should check with the rollforming supplier who can arrange this through the BlueScope Sales Office. For more information, please refer to Technical Bulletin, TB-19 - COLORBOND steel – visual considerations in large single planes.

Good building design requires some planning in the selection and use of materials. All building materials reflect sunlight and can benefit occupants and the environment by reflecting the sun's heat away from the building, however under certain conditions, this may cause annoyance to immediate neighbours. For more information, please refer to Technical Bulletin, TB-28 - Building materials and reflectivity.

Fungus/mould or lichen can sometimes grow on a variety of building materials, including COLORBOND® steel, in tropical and temperate areas of Australia. Fungal growth occurs where the prevailing ‘local environment’ or an isolated ‘microenvironment’ are conducive. This fungal growth can be removed with the appropriate cleaning agents. For more information, please refer to Technical Bulletin TB-27 - Identification of fungus in the field and recommendations for its removal.

Swarf is the term given to steel debris that is created during cutting or drilling operations when your roof is being installed. Swarf particles can corrode rapidly and cause unsightly stains that will detract from the appearance of the roof. Prevention of swarf staining is the responsibility of the installer and following trades. Care should always be taken to properly clean up any swarf created during the installation process by blowing, vacuuming, sweeping or rinsing the roof to remove loose particles. For more information, please refer to Technical Bulletin TB-05 - Swarf Staining.

Roofing made from COLORBOND® steel comes in a wide variety of profiles, and it is the profile of your roofing material that determines the minimum pitch that it can be placed at. For example, a corrugated profile typically has a minimum pitch of 5 degrees however some profiles can have a minimum pitch as low as 1 degree. We recommend speaking to your builder, designer or roofing supplier to determine the appropriate pitch for your desired roofing profile.

BlueScope Steel does not recommend the use of touch up paints on COLORBOND® steel.

The manufacturing process that gives COLORBOND® steel its colour and gloss retention properties means that the surface weathers differently to air-drying paint. After weathering, the areas which have been touched up will look different and can leave a blotchy look.

For more information on this we recommend reading our technical bulletin here.

You can get a quote or order COLORBOND® steel via our suppliers.
