Where it works
Roofs, walls and everything between.
- Low-pitch skillion roofs
- Commercial and industrial buildings
- Modern homes and extensions
- Wall cladding
9 Rib has a bold, architectural look and, because its ribs sit close together, it is strong for its weight. It is a popular choice for low-pitch skillion roofs and for wall cladding where a sharper line is wanted.
It is an equivalent profile to Lysaght Spandek®, supplied by Roofing Depot on the Gold Coast. Flashings, cappings and barges are made to match in the same colour.

Common questions
9 Rib (Spandek-style): common questions.
What are the dimensions of a Spandek-style 9 Rib sheet?
Cover width 700 mm, rib height 24 mm, rib spacing 87.5 mm centre to centre and a rib top of 22.9 mm. Sheets are cut to any length up to 10,000 mm.
How many 9 Rib sheets do I need?
Measure the roof along the gutter in millimetres and divide by 700, then round up. A 6,000 mm wide roof needs 6,000 ÷ 700 = 8.6, so 9 sheets.
Is your 9 Rib the same as Spandek?
It is an equivalent profile supplied by Roofing Depot. Spandek® is a trade mark of Lysaght; our sheets are not manufactured by Lysaght.
Can 9 Rib be used on a low-pitch roof?
Yes. 9 Rib is suited to low-pitch roofs down to 1°. Very low pitches need care with end laps and flashings; ask us and we will confirm the detail for your roof.
How long does it take?
Normally ready within two business days of your order being confirmed. Collect from Coombabah or have it delivered, with freight quoted for your suburb before dispatch.
