Carsonite was founded in 1975 by a team of engineers developing special fiber-reinforced materials for the U.S. space program. Their objective: put advanced composite technology to work for innovative, safety-oriented products for highway, utility, and recreational uses — technology patented and registered under the brand name "Carsonite."

It's a tradition we proudly uphold. Over the years we've added many new products, originated and patented many new technologies, and continued to strive to make the highways, the work place, and recreational areas safer.

Having introduced the first flexible highway delineation post more than two decades ago, Carsonite continues to lead the way in such highway and work-zone safety products as driveable and surface-mounted roadway delineators, mileposts, and hazard markers, all capable of sustaining repeated highway-speed impacts and coming back for more, plus rumble strips, speed bumps, and car stops, as well as accessories including snowpoles, street signs, decals, and reflective sheeting.

Our award-winning AcoustaShield™ Sound Barrier System not only helps curb noise pollution but helps remove scrap tires from the waste stream. The system features tongue-and-groove boards of glass-reinforced polymer composite, filled with pulverized tire scrap. A mile of Carsonite Sound Barrier 10 feet high consumes a stunning 211,000 pounds of tire scrap, ridding the environment of nearly 21,000 discarded tires.

More than 60 percent of utility service interruptions can be blamed on accidental rupture by excavation. We help eliminate that problem with our high-visibility, high-durability products for clearly and permanently identifying the locations of underground electrical cables, gas lines, fiber-optic cables, and water lines. And Carsonite is 100-percent "811" ready.

For parks, playgrounds, ballfields, and other recreational facilities, we provide flexible athletic fencing, signage, and posts — attractive, rustproof, and vandal resistant, plus a complete line of stock and custom signs and decals.

Facilities & Capabilities

Carsonite Composites operates two manufacturing facilities in South Carolina. The facilities employ two plastic extrusion machines with combined annual capacity of 5.7 million linear feet. Our 35,000 square foot composites facility in Varnville, South Carolina houses three 6,000-gallon resin mixing tanks and 11 pultrusion lines with one to four die cavities each. Carsonite's graphics operations are performed using state-of-the-art, computer-controlled graphic-arts plotters, using materials and processes that maximize outdoor durability factors. Our extensive finishing operations include lamination, direct graphics, drilling, assembly, and a variety of other tasks to make our products as customer-friendly as possible.

There is only one original Carsonite. We originated many of the products we sell, and we make ours better, longer lasting, and capable of withstanding more abuse - from vehicular impacts, attempted vandalism, even small caliber gunfire and controlled ditch burns. Our products are known in the industry for quality - one of our competitors has been caught boasting "as good as Carsonite." We achieve that quality by continuously monitoring all of our processes, and by a rigorous program of testing to make sure our products deliver on our performance promise. You cannot buy better markers. Period.
