More Information: COLORBOND® Corrugated Roofing Sheets .42 BMT

Our genuine COLORBOND® Corrugated Roofing Sheets in .42 BMT are one of the most popular choices for Australian homes, sheds, garages, patios and carports. Manufactured from premium BlueScope steel, this traditional corrugated roofing profile combines the classic Australian look with reliable everyday performance.

Why Choose COLORBOND® Corrugated Roofing Sheets?

• Classic corrugated roofing profile trusted across Australia

• Made from genuine BlueScope COLORBOND® steel

• Custom cut to your required lengths

• Strong, lightweight and easy to handle

• Suitable for reroofing, new builds and renovations

• Wide range of genuine COLORBOND® colours available

Is .42 BMT Right For Your Project?

.42 BMT is the most common thickness selected for standard residential roofing applications where normal spanning conditions apply. It offers an excellent balance of strength, weight and value.

Many customers choose .42 BMT for:

• Homes and extensions

• Sheds and garages

• Patios and verandahs

• Carports

• General replacement roofing

If your build requires heavier specifications, higher wind ratings or engineering requirements, .48 BMT or a concealed-fix profile such as COLORBOND® Klip-Lok 700 Hi-Strength roofing may be worth considering.

Sheet Coverage & Custom Lengths

Each corrugated sheet provides 762mm effective cover. This is the usable installed width after sheet overlap and is important when calculating how many sheets you need.

We cut sheets to the lengths you enter when ordering online, helping reduce waste, minimise joins and speed up installation.

Genuine COLORBOND® Colours Available

Choose from Australia's most recognised steel roofing colours including Monument®, Woodland Grey®, Surfmist®, Basalt®, Shale Grey® and more.

Many customers match their roof sheets with gutters, fascia and roof flashings for a cleaner finished look, while others choose alternative profiles like COLORBOND® Trimdek roof sheets for different aesthetic and spanning requirements.
