Which letter is used to designate deformed wire in welded wire reinforcement?

In welded wire reinforcement (WWR), deformed wire is designated with the letter "B." This designation indicates that the wire has surface deformations, which enhance mechanical bonding with concrete. The deformation improves the reinforcement's ability to withstand tensile forces and contributes to the overall strength and stability of the concrete structure.

Deformed wire has specific shapes or ridges, making it more effective at carrying loads compared to smooth wire. This property is crucial in construction, as it provides enhanced anchorage within the concrete matrix. The standardization of these designations helps manufacturers, builders, and engineers communicate more effectively regarding the materials used in construction.
