FAQs

There are generally two types of warranty available to consumers of BlueScope Steel products:

• A warranty against defects is known as a "Manufacturer’s Warranty", this covers the materials, such as COLORBOND® steel, that certain steel products are made from.
• A Performance Warranty, or "Express Warranty", assures consumers that the end product will perform as expected for a specified period.

For more details, such as whether a warranty is available for your desired application and product selection, the applicable terms and conditions or how to apply for the warranties, please talk to your supplier or go to our relevant product section of this website. In addition, consumers have rights under the Competition and Consumer Act 2010 which cannot be excluded, modified or restricted.

All coloured materials will change colour when exposed to UV light - the paint finish on your car, the clothes on your line, and so on. When it comes to steel building materials, the extent of colour change is influenced by factors such as the colour itself, the aspect, the design of the structure and the environment. Dark colours are inherently prone to more noticeable colour change than lighter colours. Individual perceptions also come into play. How you see colour can differ greatly to someone else.

COLORBOND® steel does not have a Fire Rating.

Information about the Early Fire Hazard ratings for COLORBOND® steel can be found in our Product Datasheets.

• It is recommended that ZINCALUME® steel not be heated above 200°C.
• It is recommended that zinc coatings not be heated above 250°C
• COLORBOND® steel should not be heated continuously above 100°C and intermittently 200°C.

The appearance of COLORBOND® steel affected by weathering can often be restored by re-painting. Please contact a roof restoration expert to assess the suitability of the roof for re-painting. If the roof is in a suitable state for re-painting please refer to the BlueScope Steel guidelines for overpainting, found in Technical Bulletin 2.

You're probably looking at swarf stains. Swarf is the term given to the steel debris arising from cutting or piercing operations, and mostly comprises of fine steel particles mixed with abrasive, however, in this context swarf may also be taken to include any other discarded steel objects such as rivet shanks, nails, screws and nuts, which may come in contact with coated products such as COLORBOND® prepainted steel and ZINCALUME® zinc/aluminium alloy-coated steel.

Swarf particles, if left on the surface, will corrode and cause rust stains which will detract from the finished appearance of a project. These stains are often mistaken for early deterioration of the roofing and walling itself.

The following link contains a guide for removing mild and severe staining from prepainted steel sheet and metallic coated steel sheet.

With steel building frames made from TRUECORE® steel, mortar splashes from bricklaying operations are rarely a direct cause for concern. However, TRUECORE® steel, ZINCALUME® steel and COLORBOND® steel (manufactured with a ZINCALUME® steel substrate) should not be immersed in wet cement, as rapid corrosion and degradation of the alloy structure will quickly occur. Should splashing occur, the concrete should be removed immediately before it is allowed to dry, as it then not possible to remove without damaging the product. A few small splashes are unlikely to cause significant damage to the product surface; however our warranty does not cover failure of the product in such circumstances.

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.
