LYSAGHT TRIMDEK®
Product Description and Features
LYSAGHT TRIMDEK® is a subtle square-fluted steel cladding, available in long lengths, so on most jobs you can have one sheet from ridge to gutter without end laps.
LYSAGHT TRIMDEK® is made of high strength steel and despite its lightness, provides excellent spanning capacity and remarkable recovery after deformation.
The strength, spanning ability, lightness and rigidity of LYSAGHT TRIMDEK® permits wide support spacings to be used with safety.
- Can be used for both roofing and walling applications
- Available in a wide variety of COLORBOND® steel colours
Note:
- Walk only in pans and close or over the supports
- May be used on roof pitches from as low as 2 degrees (1 in 30)
- Read our Guidelines for using COLORBOND® steel & ZINCALUME® steel.

How can I identify LYSAGHT TRIMDEK® from other look-a-likes?
The easiest way is to look at the pans. LYSAGHT TRIMDEK® has a single crease along the centre of the pan. Other "look a-likes" have a single or double flute in the pans.
When fixing LYSAGHT TRIMDEK®, how many ribs have to be fastened?
It is necessary for every rib of LYSAGHT TRIMDEK® to be screw fastened to the support.
What is the best way to walk on LYSAGHT TRIMDEK®?
It is good practice to only walk in the pans, however at supports only it is safe to stand on the ribs.
What is cladding and how does it relate to roofing and walling?
Cladding is a collective term for any sheeting that covers a building, whether it be on the roof of the building, or on the walls. Roof cladding is made from thicker steel and is rolled to a profile capable of supporting roof traffic*. In most cases, these roof claddings can also be used for walling as well. Wall cladding is made from thinner steel, rolled to a less rigid profile. They are generally not capable of supporting roof traffic, prohibiting their use as roofing.
*Some roofing is designed to be non-trafficable. Please consult the span and capacity tables of the cladding for further details.

Span Tables
The maximum recommended support spacings are based on testing in accordance with AS1562.1-1992, AS4040.1-1992 and AS4040.2-1992. Supports must not be less than 1mm BMT.
Roof spans consider both resistance to wind pressure and light roof traffic (traffic arising from incidental maintenance).
Wall spans consider resistance to wind pressure only.
The figures relate only to buildings 10m or less in height and located in sheltered or exposed suburban areas or sheltered rural areas only, for further details Download LYSAGHT TRIMDEK® (822 KB).
