Designs are typically based on the following: Standard Marine structures Ductile cast iron is the preferred material for all bollard applications. Grey cast iron is cheaper per unit weight, but the need for thicker wall sections and poor impact strength outweighs this. Cast steel remains popular in some countries but needs regular painting to prevent corrosion. Mechanical equipment design...
