Carsonite

What Carsonite does

Carsonite, founded in the early 1990s and headquartered at 19845 U.S. Highway 76 in Newberry, South Carolina, is a product brand and manufacturer of composite safety posts, markers, delineators, sound barriers, and related signage and accessories used in highway, utility, and parks and recreation applications across North America. The brand operates as a product line under Valmont Composite Structures, Inc., itself a subsidiary of publicly traded Valmont Industries, Inc. (NYSE: VMI), a global conglomerate that manufactures in 22 countries and serves customers in more than 100 countries across infrastructure and agricultural segments. Carsonite leverages Valmont's in-house technical expertise and global resources to produce composite safety products made in the United States.

Carsonite's core technology is fiberglass reinforced composite material manufactured via a heated pultrusion process, with products engineered to flex on impact and return to position, resist corrosion and UV exposure, and deliver service life of up to 50 years. The product portfolio is organized into five categories: highway delineators and accessories (RoadMarker, Curv-Flex, Dual Sided Marker, Tuff-Flex, Boundary Marker, FlexGuard, Survivor, GreenLine, Modular Guidance System, guardrail and cable delineators, flexible fence); utility markers and test stations (Utility Marker, Utility Sentry, LineMarker, PermaPost, Visipost, and several cathodic/telecom test station variants); sound barriers (SoundWall and the award-winning AcoustaShield); signs, decals, direct print graphics, and reflective sheeting; and parks and recreation products including parking and traffic signs, campsite markers, and flexible fencing. Many marking products incorporate proprietary trademarked profiles that are industry standards, and AcoustaShield is certified to meet AASHTO and DOT sound wall guidelines.

The company generates revenue through one-time hardware sales via three channels: a network of direct sales representatives handling custom-engineered solutions and enterprise accounts, a vast North American distribution network serving highway, utility, and parks markets, and an online store (shop.carsonite.com) for standard products. Pricing is not publicly disclosed; quotes are provided on request. End customers include government transportation departments, road construction contractors, telecom/gas/electric utility companies, municipal authorities, and federal, state, and local parks and recreation departments. No revenue figures are disclosed.
