Product Description

B5/B6/B7/B8/B9/B10/B11/B12/B14/B16 reinforcing mesh with ribbed
Reforcing mesh is also called welded steel bar mesh,rebar welded wire mesh,rebar mesh,BRC mesh,reinforced mesh panel etc.
Our reinforcing mesh is welded by GWC welding machine of which the welding procedure is automatically controoled by computer. The aperture is even, quality is good, and the mechanical properties of steel bars are barely chaged before and after welding.
Heyou buy the material of reinforcing mesh (Q195,CRB550;CRB600H,HPB235,HPB300,HRB400) from the steel factory which has good reputation in steel field.

Advantage of reinforced steel mesh:
Reinforced steel mesh is finished on automatic and intelligent production line,which is controled stictly in mesh size, rebar wire diameter and quality.Especially,big rigidity,good elasticity, accurate spacing and high strength welding spot.Therefore improve and guarantee engineering quality.  
The longitudinal and transverse bars of reinforced steel mesh are formed a net structure which bonded firmly with concrete,and bearing-loading can be distribeted evenly,which obviously improves the seismic and crack resistance of reinforced concrete stuctures.

Application of reinforced steel mesh fabric:
Highway Cement Concrete Pavement Engineering
Bridge Engineering
Tunnel Lining surpport and reinforced

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.
