"Our bollards are extremely strong and are powder coated in a ""Safety Yellow"" color to allow them to be easily seen no matter what the conditions are. The main benefit besides the protection offered by these bollards is the fact that there is no required concrete work to allow these bollards to be efficient. Being that this bollard is 6"" in diameter and 42"" tall you will be able to offer a strong and reliable barrier from any potential hazard."
