Relative strength of wire mesh vs rebar for reinforcing a concrete slab
There are also disadvantages: Wire mesh is often produced by cold-drawing - which can decrease the ductility in comparison to standard steel bars. Lap splices can be more awkward due to the cross wires being welded in place. This paper has a more detailed comparison of Welded Wire Mesh and conventional reinforcement Share Improve this answer

What are the benefits of using bar and mesh reinforcement in reinforced ...
Answer (1 of 2): Steel wire mesh (better known as welded wire fabric) is the typical reinforcement used in concrete slabs on grade. It is cheaper as a material and cheaper to install since it is less labor-intensive than laying a grid of individual bars. Deformed steel bars (rebar) are used in s...

Concrete vs. Steel: Pros and Cons of Each - BuilderSpace
The corrosion of steel lessens the useful cross-section of structural components like columns, slabs, and beams. Additionally, in buildings where there is a steel-concrete bond, corrosion can have a significant impact. The steel reinforcement will start exhibiting an imperfect bond with the surrounding concrete, reducing the unit's capacity.

Rebar in Concrete: Does Concrete Slab, Patio, Driveway Need Rebar?
The reinforcing steel allows concrete to withstand more weight, tensile stresses, vibration, and even shifts within the soil strata. It helps extend the life of the concrete by minimizing shifting, cracking, and breaking. Reinforced concrete may crack, but the steel prevents horizontal, vertical, and lateral separation or movement.
