Description

Single Bitt Bollard is a common mooring bollard, very often also known as pillar type bollard. It is designed and manufactured for areas with a wide tidal range.

Single Bitt Bollard is usually made of cast steel or ductile cast iron, installed with 4-8 bolts, can be accepted multiple mooring lines to withstand the use in harsh environments. It has different capacities, from 20 tons to 200 tons, and also a larger capacity as required of up to 400 tons is available. The surface is coated with rust paint, and the color can be changed according to requirements.

This bollard is suitable for high angles mooring, the face angle of cable is -45 ~ +45 (vertical), 0~1800 (horizontal). Besides, Boomarine also provides other types of mooring bollards, such as Pillar Bollard, Kidney Bollard, Staghorn Bollard, T-Head Bollard, etc. And all of our mooring bollards can offer CS, ABS, GL, NK, LR, etc certificates.

Ductile Cast Iron VS. Cast Steel

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.
