Welded wire fabric is a series of parallel longitudinal wires welded to cross wires by electric fusion method with accurate spacing. The welding work is done by machinery which ensures the precise dimensions and results in

welded wire reinforcement is governed by the ASTM A1064 Standard Specification for Carbon-Steel Wire and Welded Wire Reinforcement, Plain and Deformed, for Concrete. Welded plain wire reinforcement is characterized by smooth circumferential wire surfaces.

W.W.F. concrete refers to concrete reinforced with welded wire fabric (also known as wire mesh). This fabric is a network of steel wires welded together in a grid pattern, typically used as a reinforcement material in concrete.

Welded wire reinforcement keeps the cracked sections of a slab closely knit together so that the slab will act as a unit. When a slab cracks, the faces within the crack are jagged. If the sections on each side of the crack are held closely together, the jagged faces of the concrete are interlocked which helps transfer loads across the crack.
