Page 41 of the Rice Signs 2017 Traffic Safety Catalog explains the material specifications and use cases for Roll-Up Signs. Reflective Roll-Up Signs use reflective vinyl mesh that performs well day and night — they are the most popular choice for work zones requiring 24-hour deployment or low-light conditions. The reflective mesh material maintains visibility under headlights and is the standard for highway and freeway work zones. Non-Reflective Roll-Up Signs use a lighter, lower-cost mesh designed for daytime-only deployment — the open mesh allows wind to pass through, reducing stress on sign stands during high-wind conditions. Both types are available in the standard 36 inch and 48 inch sizes in fluorescent orange with black legend, and are sold across the Utility Work Ahead, Construction, Mowing Ahead, Lane Closure, Custom Worded, Symbol, Emergency Management, Changeable Message, and Special Event roll-up sign categories.
