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.
- Any wire size can be used from, starting at W 1.4 up to W 46.5 in increments of 0.1.
- No site space needed for steel assembly: Example
- 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. For example, for a #3 bar the cost is $5/ 100wt. while a #6 bar is $1.25/ 100wt.
- 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, 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 handing as it will remain stable in its loaded position for easy unloading and installation at the working site.
