ZINCALUME® Corrugated Iron Roofing & Cladding

Steel thickness - .48 BMT

Sheet cover - 762mm

Corrugated roof sheets Zincalume® are among the world’s most popular metal roofing products due to their high quality and versatility. These corrugated iron roofing panels are suitable for traditional and contemporary roofing projects. It is long, wide, strong, lightweight and has an economic profile that can be quickly and easily aligned. These features alone will deliver you a steel roof that offers outstanding value!

One of the most durable, long-lasting roofing materials available, and it’s virtually maintenance-free. Made from hi-tensile steel, this profile, whilst strong, is also lightweight, which minimises sheet damage. 

It can be used in roofing and walling applications, and the wide cover (762mm) allows for quick installation, saving on both materials and labour. This versatile profile can be used on a minimum roof pitch of 5 degrees.

Corrugated sheeting is pierce-fixed, which ensures easy fixing by the conventional method. To ensure maximum weather protection, our Corrugated has a 1.5 rib overlap.

Recommended Fixing Method

Here at Metal Roofing Online, we only use and recommend class 4 screws when fixing roofing as they last considerably longer in the elements. In a standard roofing application, when fixing to either timber or metal purlins, we have in our range a Multifix screw which is the perfect choice for this roofing iron.

When using the corrugated iron sheet in a wall cladding application, there is a choice between 12 gauge x 25 mm timber fix screws when fixing into the timber. Otherwise, 10 gauge x 16mm will do the trick when fixing into steel. These screws are shorter as they are fixed into the corrugation's pan (or valley).

Who is BlueScope Steel owned by?

BlueScope has a long and proud history in the Illawarra as an efficient, trusted, and innovative steelmaker.

It arose from the merger of three companies that helped to establish the Australian steel industry in the early twentieth century: The Broken Hill Proprietary Company Limited (BHP), John Lysaght (Australia) Pty Ltd (Lysaght), and Australian Iron and Steel Limited (AIS).

The company began in 1915, when BHP established a steelworks in Newcastle, New South Wales.

Lysaght, a British company, established an Australian operation in 1918 to serve the building and construction industries. Its galvanised corrugated steel has long contributed to the distinctively Australian architectural style.

In 1999, a portion of BHP Steel's assets were spun off as OneSteel. BlueScope Steel, and now BlueScope, were formed from the remaining assets in 2002.

In 2011, Port Kembla Steelworks cut production in half, exiting the export market and operating only one blast furnace.

The Port Kembla Steelworks remains the company's largest global operation, producing 2.6 million tonnes of raw steel annually. The company is a global leader in metallic coating and painting technologies, offering a diverse range of branded products, including COLORBOND® steel, ZINCALUME® steel, and the LYSAGHT® building product line. It serves its customers throughout Australia through a network of distribution and manufacturing facilities.
