How is the wire size of welded wire fabric (WWF) denoted?

Welded wire fabric (WWF) is a type of reinforcement material used in concrete construction, and its wire size is denoted by a combination of thickness and spacing. The thickness refers to the gauge or diameter of the wires used, which affects the strength and load-bearing capacity of the fabric. The spacing indicates how far apart the wires are arranged, both horizontally and vertically. This specification is crucial because it determines the structural integrity and performance characteristics of the welded wire fabric in different applications.

For example, in a construction scenario where concrete slabs are reinforced, the thickness of the wire will influence how much load the slab can carry, while the spacing will determine how evenly that load is distributed across the surface. Together, these two factors help in selecting the proper WWF for a specific project, ensuring that the material meets the necessary engineering standards and building codes. Thus, denoting wire size through thickness and spacing is standard practice in the industry for proper specification and application of welded wire fabric.
