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.

Span Tables

The maximum recommended support spacings are based on testing in accordance with AS1562.1-1992, AS4040.1-1992 and AS4040.2-1992.

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 pressure considered is based on buildings up to 10m high in Region B, Terrain Category 3. For further details Download LYSAGHT TRIMDEK® (598 KB).
