Concrete reinforcement mesh is classified ribbed concrete reinforcement mesh and plain steel wire concrete reinforcement mesh. The wire of ribbed concrete reinforcement mesh is 3 faces indentation.Please see figuer


Concrete reinforcement mesh is always used on residential slabs and footing-construction and BCA complying with AS 2870,which is always paced in all reinforced conrete members to stop the concrete cracking.
And F62/F72/F82/F92/F1018 concrete reinforcement mesh is old specification,was replaced by SL62/SL72/SL82/SL92/RL1018.For example:previously called F62(now SL62) is wire diameter 6mm bars welded together in a 200mm square grid.the panel size is 2.4m X6m.
The Tensile strength is 300Mpa.

The concrete reinforcement mesh specification as below:
Reinforcing Mesh

F62 5mm 200*200mm 200mm 2.4m 6m 20.92
F72 6mm 200*200mm 200mm 2.4m 6m 30.12
F82 7mm 200*200mm 200mm 2.4m 6m 41
F92 8mm 200*200mm 200mm 2.4m 6m 53.55
