Product information

What is TRIMDEK® and where is it used?

A trapezoidal 5-rib sheet for roofing and wall cladding on homes, sheds and commercial buildings. The bold rib carries water on low pitches, so it suits roofs as flat as 2°, where corrugated needs 5°. ZINCALUME® is BlueScope's aluminium-zinc alloy coating: it outlasts galvanised steel in coastal and high-exposure sites.

What are the sheet specs?

Base metal thickness 0.42mm BMT. Nominal cover width 762mm, overall width approx. 820mm. Rib height 29mm. Minimum roof pitch 2°. Lengths from 1.0m to 10.0m, cut to order. Support spacings are in the span table; for a heavier gauge see ZINCALUME® TRIMDEK® .48 BMT.

ZINCALUME® or COLORBOND®?

Same steel, same profile. ZINCALUME® is the bare metallic finish at the lower price. COLORBOND® adds a baked paint finish in the full colour range. For colour, see COLORBOND® TRIMDEK® .42 BMT or .48 BMT. For a different profile, see ZINCALUME® Corrugated .42 BMT.

Which screws and accessories do I need?

12 x 65mm TRIMDEK® screws into timber battens, TRIMDEK® foam infill strips at the ridge and eave, flashings and ZINCALUME® guttering to finish. 

How long does delivery take?

Each sheet is cut after you order. Delivery takes approximately 4 to 7 working days, depending on location. Select your state above for local pricing and stock.

What warranty does it carry?

Made from 100% Australian BlueScope steel and backed by the BlueScope ZINCALUME® warranty. Every product is performance tested.
