It can be divided into many different types like Single-column Bollard, double-column Bollard, single-cross Bollard, double-cross Bollard, inclined double-column Bollard, and sheep horn Bollard, etc.
(Large and medium-sized ships often use double-column Bollard.)
Wide ranges of pulling capacity available, usually from 10 tons to 200 tons High-quality SG iron as standard, cast steel also can be customized Strong and durable designs Very low maintenance Large line angles possible
