Notes:

The mass of fabric per square metre is based on a piece cut from the interior of a full sheet which is one metre square with equal overhangs on opposite sides.

Common trench mesh strip widths are 200 mm (3 wires), 300 mm (4 wires) and 400 mm (5 wires). See AS2870 Residential Slabs and Footings for applications.

Fabrics SL 63 and SL 53 have an internal mesh size of 300 mm x 300 mm. The sheet size is 6 m long by 2.3 m wide. The 100 mm closer wire spacings on the side reduce the minimum side lap to 100 mm, rather than 300 mm. They are not available in every state.

Although the fabrics listed above are generally available ex-stock, we recommend that designers and users check with their local ARC office if they have any questions about properties or availability.
