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. 

Standard mesh is belong to reinforcing mesh, the spacing of standard mesh is 200mm,overhang length is 100mm of four sides, and the popular size is A393, A252, A193, A142, B1131, B785, B503, B385, B283, and D49. We have plenty of these A type, B type and D type stocks perennially. The stocks of traditional standard mesh is manufactured in panel size 2.4m x 4.8m. and the material is B500A, which is conformed with stanard BS4483: 2005 and BS8666: 2000.

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.

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.
