Welded Wire Mesh
Welded wire mesh (welded wire fabric) is a grid of steel wires welded at each intersection, used as light, uniform concrete reinforcement for slabs and pavements where a mesh gives faster crack control than individually placed bars. NLS sources welded wire fabric to ASTM A185 and BS 4483, in standard sheet or roll format, wire gauge and spacing matched to the slab design.
Welded wire mesh is a grid of steel wires, running in two perpendicular directions and resistance-welded at every crossing point, supplied as flat sheets or rolls rather than individually tied bars. That factory-welded grid gives a slab a uniform, evenly spaced reinforcement pattern in one placement step, which is why it's the standard reinforcement choice for thin, wide-area concrete elements where placing individual rebar in a grid pattern would be slower and less consistent.
NLS sources welded wire fabric to ASTM A185, the American specification for welded steel wire fabric for concrete reinforcement, and BS 4483, the British/European equivalent covering steel fabric for reinforced concrete. Mesh is specified by wire diameter and spacing in both directions (which can be equal, square mesh, or different, rectangular mesh), and is supplied in standard flat sheets for slab work or rolls for pavement and long-run applications. Wire is plain carbon steel, cold-drawn for the strength gain that process gives, welded at every intersection rather than only at the edges.
On Saudi projects, welded wire mesh reinforces ground slabs, floor slabs on grade, road and yard pavement, precast concrete panels, and shotcrete or thin-shell applications where a mesh's crack-control performance suits the element better than discrete bars. It's often specified alongside conventional rebar rather than instead of it, mesh for surface crack control in a slab that also carries structural rebar for load.
NLS quotes welded wire mesh against wire gauge, mesh spacing, sheet or roll dimensions, and quantity, and returns a priced quote in USD. Standard square mesh in common gauges typically sources fastest, while custom spacing or heavier wire gauges more often carry a mill-confirmed lead time.

Frequently Asked Questions
How is welded wire mesh different from conventional rebar?+
Rebar is individual deformed bars tied into a grid on site. Welded wire mesh is a pre-welded grid of wires supplied as a sheet or roll, placed in one piece. Mesh suits thin, wide-area slabs and surface crack control; rebar carries the heavier structural load in beams, columns, and thick slabs.
Does NLS supply mesh in rolls for large pavement areas?+
Yes, welded wire mesh is available in roll format for pavement, yard, and long-run applications, alongside standard flat sheets for slab work, depending on the area and layout of the pour.
Can welded wire mesh replace rebar entirely in a slab?+
Not usually. Mesh is often specified alongside rebar, mesh handling surface crack control on a slab that still needs conventional rebar for the structural load, rather than as a full substitute in load-bearing elements.
