Minimum bending pin diameter for wired meshes

In wired meshes:
(a) The anchor should be at least 5Ø (Thus for a wired mesh with Ø10 wires, at least 50 mm)

(b) The bending pin should be at least 5Ø (Thus, in the example is Øm=50 mm) for all cases except when the transverse reinforcement wire is external and in distance ≤3Ø (thus, in example 30 mm), where the pin should be 20Ø! (Thus, in the example Øm=200 mm!!!)
