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. 
 

Trench mesh reinforcement is welded by galvanized low carbon steel wire or high quality low carbon steel wire

It divided the shape: trapezoid, triangle, two bars and three bars welding. The trench mesh reinforcement is always used on foundation construction, residential slabs, footing construction and pier beam.
 

 

1.The Advantage of Construction Reinforcement Mesh by AS-NZS 4671-2001 standard:

1. Save 30% of steel bar dosages
2. Reduce 50%-70% work time,improve construction progress and shorten construction period.
3. Cut down 5%-10% construction cost
4. Used widely,it has a good market development prospects.

What is the material of the slab mesh reinforcement?
We adopt R250N,D500L,D500N,D300E,D500E as material to make the slab mesh reinforcement, especially D300E and D500E is seismic grade.


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

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.

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
