What is the difference between Profile Mesh (V-Mesh) and Twin Wire Mesh?

Profile Mesh (V-Mesh): Features horizontal V-shaped pressings along the height of the panel to add vertical rigidity using a single horizontal wire structure. It is lightweight and cost-effective.

Twin Wire Mesh (e.g., 656 or 868): Features two horizontal wires sandwiching a single vertical wire. It contains no V-pressings, providing a flat profile with superior resistance to heavy force and vandalism.
