Turn your Trimdek Sheets up or down using this Trimdek Tool. It is usual to allow roof sheets to overlap into gutters by about 50mm. If the roof pitch is less than 25° or extreme weather is expected, the pans of sheets should be turned down at the lower ends and turned up at the upper ends by about 80°.

Trimdek, in particular, pertains to square-fluted steel cladding that is available in long lengths. This means that one sheet can be used from ridge to gutter without having any end laps. Trimdek is remarkably strong (it can easily recover from deformation), has excellent spanning capacity, is lightweight, and is properly rigid. And of course, it is available in a wide variety of colours that Colorbond roofing steel is well known for — earthy colours that reflect Australia's distinct landscapes.

Who is BlueScope Steel owned by?

BlueScope has a long and proud history in 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 decided to cut production in half, effectively 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.

The company's headquarters are at 120 Collins Street in Melbourne, and distribution centres are in Melbourne, Sydney, Brisbane, Perth, and Adelaide.
