Marine mooring bollards



We supply marine mooring bollards  in many popular shapes and sizes to suit most docks jetties and wharves such as Tee bollard (T bollard) ,pillar bollard, horn bollard,double bitt bollard, single bitt bollard and kidney bollard. Usually we use spheroidal graphite (SG) cast iron /  Ductile cast iron, cast steel and grey cast iron as standard material. We are able to design bollards to facilitate the accommodation of large vessels with more acute mooring angles at quayside.

Spheroidal graphite(SG) cast iron/ Ductile cast iron is the preferred material for all marine mooring bollards applications owing to the benefits of lowest service life cost,high strength,good impact resistance and high corrosion resistance,we usually suggest this material firs.

Cast steel marine mooring bollards are good cost per weight ,high impact resistant and high strength that make this material popular in some countries ,but compared with Ductile cast iron, cast steel bollards are easy to get rusty so regular maintenance is necessary to prevent corrosion.

Grey cast iron are excellent corrosion resistant and cheaper per unit weight but the need for thicker wall sections and poor  inferior mechanical performace such as low strength and low impact resistance make grey cast iron last material for marine mooring bolalrds
