The single post sign assembly becomes the workhorse for most sign programs. Terrabilt offers a wide selection of standard panel sizes to accommodate common applications in single panel and modular assemblies—both single face and with panels on front and back of the upright. Graphics are available with both fused image on aluminum (full color graphics) and retroreflective sheeting on aluminum (for motorist guidance and traffic control applications). Special panel shapes are available. Unique shapes can be developed upon request.
