Detailing reinforcementsMesh – fabric detail

Fabric is specified in term of the AS1304 standards.

Refer to Table 2.6 p2.42 (SB2)

For detailing – the important information are:- Type – e.g. F82 Longitudinal / Cross wire

pitch – e.g. 200 / 200 for F82

Longitudinal / Cross wire size – e.g. 8 / 8 mm for F82 ; 12.5 / 8 for F1218
