Welcome to Blender Wireframe Modifier overview. A feature of Blender 2.70, it provides an easy way of making wireframe render in Cycles. But its great not just for visualization. It can be put on top of cloth simulation to make a fishnet. In general, this tool opens up many modelling scenarios for us.
Blender Wireframe Modifier Tips
To assign wireframe a different material, use Material offset.
Relative Thickness can be used to give the appearance of uniform wires (wires that are relative to polygon size).
