The longitudinal and transverse reinforcement bars are welded into concrete wire mesh. The concrete meshes have a more dense spacing of the steel bar. Concrete wire mesh is also named welded steel fabric.
Concrete wire mesh is used for reinforcement, concrete pavement, bridge deck pavement, airport runway, tunnel lining, housing floor, roof, wall, floor, concrete pipes and so on
Welded Wire Mesh Advantages:
- Because bars are welded in a mat, the bars do not move when concrete is placed, insuring bars are in their proper position.
- Since WWR is prefabricated and welded in plants, the risk of missing a bar is minimized.
- The chance of improper bending of bars is reduced by using WWR since bending machines bend the mat as a single unit.
- The use of WWR minimizes the chance of misplacement since only one type of mat is used on a given section.
- Provides the exact size of reinforcement where needed through variable bar size and spacing, thereby reduces steel waste.
- No site space needed for steel assembly.
- Faster erection time means you can beat changing weather conditions.
- Removes reinforcement placement from the critical path.
- Barrier walls on bridge deck construction could be constructed faster. This reduces the time for fall exposure and insurance premium costs.
- WWR can reduce construction time, thereby saving: equipment leasing time.
- Material cost is decreased because the small bar is not fabricated.
- Less field labor needed.
- The material fabrication is automated.
- The process of hard drawing results in every section of wire being actually tested as to tensile strength thereby rendering it a more reliable material.
- With welded wire fabric there is no laying of single bars, no binding, no cutting, no bending, no hooks, and no small pieces to be lost.
- Fabric is quick and easy to lay, and once in position is not readily displaced by workmen when laying the concrete, as in often the case when rods are used.
- The bonding area of a close mesh fabric with welded joints is several times greater than manually assembled rebar, since the mechanical anchorage action of cross welded joints offers much superior pull-out strength compared to the mere peripheral bonding in manually assembled rebar.
- Economical. Using steel mesh requires less steel reinforcement than using steel reinforcement bars.
- Safety. Because the mesh is formed by electro welding versus the alternative methods.
- Cost. There can be a considerate savings because mesh is easy to handle and can be installed much faster.
- Effectiveness. Mesh stays where you put it and has excellent adherence to concrete.
- The products is well suitable for shipping and handling as it will remain stable in its loaded position for easy unloading and installation at the working site.
