Fabricated by twisting wires together

Explanation:
Strands are formed by twisting multiple wires together to act as a single unit. This twisting creates a flexible yet strong component that can be laid up with other strands to form wire rope, which is common in bridge cables and suspensions. The other terms describe different forms: bars are solid, rods are round reinforcing elements, and mesh is a welded fabric of bars. None of those are produced by twisting wires together, so the concept of twisting wires to create a unit points to strands.
