Welded wire mesh is produced within TS 4559, DIN 488,BS 4483, ASTM-A 497 standarts.
| Definition of the welded wire mesh |
Welded wire mesh is a prefabricated steel reinforcing material. It is manufactured from S220 cold drawn, ribbed and high yield strength steel wires especially used in construction. welded wire mesh bars are produced with cold rolling Bst IVb iron or Bst 50/55 (RK) minimum carbon St I iron and deformed specially.Bars, which are drowned in cold rolling processes are cut in cutting machines. After that the bars are processed by electronic programmed tack welding machines. Welded wire mesh has been manufactured with TS-4559, DIN 488.BS 4483,ASTM-A 497 norms. The details about concrete steel bars used in steel mesh, are specified in TS 708.
In additional to this St IV b bars can use in constructions as steel mesh, you can find detailed info about steel mesh in steel mesh page
GUVEN welded wire mesh is successfully and economically used in all assorts of concrete structures, such as slabs, walls, webs, beams, and column footing, highways, tunnels and galleries. They are especially suitable for concrete reinforcement.
Apart from these, there are other available welded wire mesh types which are used for garden fencing safety railings and suspended ceilings.
According to the costumer demand, these can be manufactured as hot dipped galvanized and polyester painted.

Standard welded mesh is manufactured in R and Q types.
R welded wire mesh: R wire mesh type which works and carry on one direction, Vertical pipe space is 150mm horizontal pipe space is 250mm in all R type wire mesh.
Q welded wire mesh: Q type wire mesh which works and carry on both directions.
Vertical and horizontal pipes space is 150 mm.
Standard wire meshes are 5.0/2.15 m and easy to transport. vertical pipes can be double but horizontal pipes must be single, special wire mesh can produce at every section with in, 8m vertical pipe and 2.80m horizontal pipe diameters.

| Advantages of welded wire mesh |
1 : Because of double more confidence tensile from normal building wire, welded wire mesh saves material %40 more than Norman building wire (STI). For STI Ve=1400 kg/cm2 but for wire mesh Ve= 2400 kg/cm2 so it saves material almost double more.
2 : Steel mesh can be carried and montage easily because of less material than others and it is in plates.So it makes timesavings.
3 : Labour Cost Saving:Steel mesh can laid down easily.Because it doesnt need processes like straighten,making hook or cutting bars threadly. Because of short steel mesh laying down, you save 50 %.
4 : Transporting Saving: Steel mesh are manufactured in 500 x 2.15 standards so it can be transported easily and it saves also money because of easy transport.
5 : Material saving,time saving and labour cost saving make money saving between 10 %-20%.
6 : Quality Advantage: Steel meshes are manufactured with automatic welding machines for full scantling vessel.Steel mesh bars show dispersal homogeneity.Aderance of bars are accured because bars are drawnd and welded.So cracks,corosions and leakage are abolished.
7 : Steel Mesh Certificated TSE: It has manufactured with calibre and length standards so it don’t let losess of calibre and lenght.
8 : Agio; Steel Mesh is in Public Works price list with 23.010 and 23.011 pose numbers.Price difference in steel mesh is set ad 8 mm iron according to Law No. 88 / 13811 Cabinet Decision which was published in No. 19905 official gazete in 20 August 1988.
