What feature makes wire fencing somewhat flexible?

The feature that contributes to the flexibility of wire fencing is primarily the material used to construct it. Different materials, such as galvanized steel or softer metals, offer varying degrees of flexibility and strength. For instance, a wire made from a more pliable metal will bend and flex more easily compared to a harder, more rigid material. This flexibility can be advantageous in applications such as environments with high winds or where the fencing needs to absorb impacts without breaking.

While the installed height and the number of wires might influence the strength and security of the fencing, they do not directly correlate with its flexibility like the material does. Similarly, the color of the fencing is purely aesthetic and has no impact on its structural properties, including flexibility. Thus, the choice of material is the key factor that determines how flexible the wire fencing can be.
