Glasform’s fiberglass reinforced composite utility marker posts and highway delineators are designed to withstand multiple vehicle impacts and return to an upright position. Markers come in lengths of 62, 66 and 72 inches and come in several colors. According to Glasform, fiberglass combines a blend of strength and flexibility for easy installation and a long service life. Being a naturally rust, rot and corrosion resistant material that can withstand temperature extremes, Glasform’s marker posts and delineators can perform in the -60 degree F weather of the Arctic as well as survive forest fires, the company says.
