Switched from Construction/Engineering Grade sheeting to High-Intensity sheeting for barrels and barricades

Iowa requires all project signs (either skid-mounted or post-mounted) to use fluorescent orange sheeting (Iowa Type VI or Iowa Type VII). The sheeting products approved in Iowa are found in two files: 486.03aa.pdf and 486.03.pdf. Effective January 1, 2007 all orange on work zone devices are also Iowa Type VI or Iowa Type VII.
