The normally used material for mooring bollards is cast steel and ductile cast iron.
Both of them have their advantages during applications. Advantage of Ductile Cast Iron: more corrosion resistance than steel and can tolerate compromised coatings better than steel. Ductile cast iron is more fluid during the casting stage which results in a smoother finish. Advantage of cast steel: available in a wide range of strength, this allows the bollard to be commercially competitive versus thicker cast iron bollards. The ductility of cast steel gives needed structural margin in the event of an overload situation.
