TRIMDEK HI-TEN STEEL ROOFING PROFILE
TRIMDEK HI-TEN steel sheet is a lightweight, high tensile strength (550 MPa), trapezoidal ribbed, roll-formed roofing and cladding profile. It has widely spaced ribs and available in long length, governed only by transport considerations.
The effective cover width is 1000mm/760mm (± 4mm). The rib height is 32mm/29mm (± 1mm).

V-CRIMP HI-TEN STEEL CLADDING PROFILE
V-CRIMP HI-TEN steel cladding is a tough double – V wall profile that resists deformation over long spans – which means it can really take the knocks. It can be used vertically and horizontally and although used mainly for commercial or industrial cladding, it does not take a lot of imagination to see how it could be used as an interesting feature in domestic applications.

The material we use for both TRIMDEK and V-CRIMP profile sheet are colorbond® and Zincalume® from Blue scope steel Astralia and the details of which are as follow as circulated by Blue scope steel.

The name BlueScope Steel is itself a powerful brand. It represents the strength and traditions of our company from its pioneering origins in the Australian steel industry to its position today as a market leader providing high levels of service, and trusted and inspired steel solutions to our customers.
In conjunction with the BlueScope Steel brand, we are also famous for some of our leading product brands. Brands such as COLORBOND® steel (since the 1960’s) and ZINCALUME® steel (since the 1970’s) have been leading names in the building and construction industry, known widely as versatile, high quality steel building materials.

More recently, Clean COLORBOND® pre-painted steel – the “Defence System against Tropical Staining” – was released throughout Asia in 1999. The unique paint system of Clean COLORBOND® steel prevents fine dirt and other particles from bonding to the building surface even in the very hot and humid environments of Southeast Asia

BlueScope Lysaght, founded in 1918, is the steel roll-forming business of BlueScope Steel, a name that has remained synonymous with quality throughout the decades. From DIY home improvement kits through to structural products for large construction projects, there is a LYSAGHT® solution for every building application.
