Our delineator u-channel sign posts are manufactured from high quality, high tensile rail steel and finished with a protective coating of weather resistant baked enamel paint, or galvanized. They are designed to provide an attractive appearance and years of maintenance-free service. Delineator posts are smaller and thinner than standard U-channel posts. They provide a cost-saving solution when the application does not require a heavier post. Additional sizes are available upon special request.
