I was wondering, what type of roll-up signs are used in your area - mesh, non-reflective vinyl, or reflective vinyl?
Here in the Phoenix area, reflective vinyl now seems to be the norm, including for Fluorescent Pink incident management signs. My guess its key advantage is that it can be used at night. I haven't seen a mesh sign in years.
I'm pretty sure Nevada uses reflective vinyl for any roll-up signs (construction warning, mostly).
I don't think I've ever seen a mesh sign...
Mesh signs are garbage. Not only do people always end up using them at night, they get stained very easily by the dirt, grease and oil that can be found in the back of a work truck.
