This striking cladding features slender, high ribs and broad, flat pans that make a dramatic statement on any structure. Using a concealed fixing system to maintain its clean lines, LYSAGHT LONGLINE® cladding can be tapered for a fan-like effect where curvilinear roofs require a tailored cladding solution.
Sheets are supplied custom cut to length. Minimum and maximum lengths apply. Please contact your nearest LYSAGHT® office for your region for more information.

As LONGLINE 305® has a flat pan finish with no flutes, the material can exhibit signs of oil canning. This can exist for all COLORBOND® steel colours but is potentially more visible in the darker COLORBOND® steel colours in the range. This can be seen in the finish of the product so designers need to make a professional judgement in its suitability for the application. Oil canning is not a structural defect simply an aesthetic issue. Please consult with the Lysaght technical enquiries team for advice.

Disclaimer: Please note that all flat pan profiles can exhibit signs of oil canning under certain light conditions which can potentially be seen in the finish of the product. While this appearance can differ for all colours, it is typically more visible in darker colours. Oil canning is not a structural defect but simply an aesthetic issue. Designers should take this aspect into account upon selection and need to make a professional judgement on the profile suitability for the particular application. Please consult with LYSAGHT® technical team for any additional advice.

The college was established in 1863 by the Catholic Sisters of Mercy and is part of the Ipswich Heritage Trail. An important icon for the local community it is a prominent landmark for the city.
The new Riverside Precinct replaces a string of demountable buildings that were previously situated on the college’s “prime real estate” on a rise overlooking the Bremer River.
