Product Description

F62/F72/F82/F92/F1018 concrete reinforcement welded wire mesh

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

3.Each sheet of reinforcing mesh panel shall include number of bars,pitch,length,width, and overhang dimensions. And the bar arrangement of reinforcing mesh panel has single bars,twin bars or combination of single bars and twin bars.
 4.The technical data of reinforcing mesh panle is contained composition and characteristic mechanical porperties of reinforcing steels.

Notes:

1. Grade 250N is supplied as plain round reinforcing steel complying with AS 3679.1,exceptthe tolerance of the diameter and roundness dosen't apply it.
2. For 500L steel bars,only requriement for wire diameter is less than 5.0mm is R_ekL≥500

Material certificate of reinforcing mesh as below:
 

How can we conctrol our products quality for exporting Autralia?
Firstly,we purchase the material from Steel Factory and inspect chemical composition and mechnical property of reinforcing mesh panel in our in-house laboratary according to AS 1554.3.

Secondly,the panel size tolerances meassure way as:

1. Panel Size dimensions≤6m in length,there is 40mm tolerances.
2. Panel size dimensions>6m in length,the tolerance is ±0.7%
3. Wire diameter and mesh size measure and weld shear resistance test conformance to AS NZS 4761-2001 and as per contract.
4. Weigh the each bundle weight to calculate each panel weight.
