Product Description
Reinforcing Welded Wire Mesh is also called Construction reinforced concrete mesh, Concrete reinforcing mesh ,wire steel bar mesh, steel concrete mesh. Reinforcing Welded Wire Mesh is longitudnal reinforcement and transverse reinforcement were arraanged in a certain interval and at right angles to each other, all the intersections are welded together.
It was made by deformed bar after drawn, which is accorded to Australian/New Zealand Standard AS-NZS 4671-2001. The material is 250N, 300E, 500L, 500N and 500E, the mesh spaces is 200mm, there is two sides overhang which is 100mm.

We adopt R250N,D500L,D500N,D300E,D500E as material to make the slab mesh reinforcement, especially D300E and D500E is seismic grade.
The production process of reinforcement steel mesh
| Firstly,Purchase wire rod from steel factory | Secondly,Test the raw material tensile strength |
 |  |
| Thirdly,drawing wire diameter as per contract | Fourthly,Straight and Cutting wire as per contract |
 |  |
| Fifthly,The reinforcement steel mesh welded by automatic and electric resistance machine | After finished producing,the reinforcement steel mesh has a good condition storage. |
 |  |
| Clearly and visible notches | Firmly and strong solid joint |
 |  |
| Messured wire diameter of reinforcement steel mesh | Messured mesh space of reinfocement steel mesh |
Our products packing and shipment: |  |
| Steel pallet for reinforcing mesh size 2.4m *6m | Loading container for reinforcing mesh sheet:2.4m *6m |
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.

- 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.
- For 500L steel bars,only requriement for wire diameter is less than 5.0mm is RekL≥500
- Panel Size dimensions≤6m in length,there is 40mm tolerances.
- Panel size dimensions>6m in length,the tolerance is ±0.7%
- Wire diameter and mesh size measure and weld shear resistance test conformance to AS NZS 4761-2001 and as per contract.
- Weigh the each bundle weight to calculate each panel weight.
