Is wire mesh still used in floor slabs florida.
When working with concrete you will be faced with 2 popular choices when reinforcing concrete.
Even small slabs which may not require reinforcement may benefit by the use of welded wire reinforcing mesh to add strength and control cracking.
To resist breaking apart and deteriorating when the slab eventually does crack to increase flexural strength of the slab.
The first is using rebar and the second is using steel mesh.
Typical method of mesh anchorage where welded wire reinforcement is bent and hooked around beam flange draped mesh concrete slabs supported by hot rolled steel beams and girders were one of the most prevalent one way floor slab systems used in buildings constructed from the 1920s to the 1960s.

These slabs consist of draped welded wire.
Steel mesh unlike rebar is easily formed making it very popular.
I would rather you use the wire mesh low slump concrete and soft cuts.

I use a 3 bar 3 8 spaced 18 inches on center placed at slightly above the 2 inch line of a 4 inch patio slab using a 2 inch plastic chair.
You can add the fiber mesh too for added insurance and it will strengthen the slab.

Typically you want to place your rebar in the upper part of the middle third of the slab but since i am using both i want the rebar slightly lower so there is room for the wire mesh to sit in the.
It does not offer the strength that rebar does but it is very close.
