T Head Mooring Bollard is also called Tee bollard or Tee-head bollard, specially designed for carrying wire ropes. This design has a “T” shaped top, hence the name. Because of its simplicity, it stands out in many parts of the world.
T Head Bollard is made of ductile iron or cast steel, using advanced casting technology, and its capacity ranges from 10ton to 200ton. The surface is coated with epoxy paint, which looks smoother and more beautiful, and also has high corrosion resistance. The base can also be of different shapes, such as round, square, semi-circular, etc., and can also be customized. T head bollards along with staghorn bollards can handle higher line load angles than single bitt bollards and kidney bollards. It is an ideal choice for everything from small leisure terminals to the largest bulk terminals.
T Head Bollard is widely used in berths for bulk minerals and liquids. It provides a simple yet efficient method for fulfilling mooring requirements to allow the safe securing of vessels next to jetties, wharves, berths and dolphins in ports and harbors.
As a leading marine equipment supplier, Boomarine strives to provide mooring bollards with superior service life and resistance to physical and corrosive environments. The products we provide will guarantee quality and reasonable price, which ensure our cooperated customers can get the maximum value and low cost. If you have any needs, please feel free to contact us.

Different Materials of Mooring Bollards
There are also some different materials for you to choose from, including spheroidal graphite (SG) cast iron / Ductile cast iron, cast steel and grey cast iron.
| Material | Standards | Grade |
| Ductile/ SG Cast iron | ASTM536 | 65-45-12 |
| Cast steel | ASTM A27 | 65-35 |
| Anchor bolts galvanised | ISO 898 | G.R.8.8 galvanised |
| Blasting | ISO 12944 | SA2.5 |
| Paint | ISO 12944 |
Class C5M |
- Ductile Cast Iron has 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.
- Cast Steel is available in a wide range of strengths, this allows the bollard to be commercially competitive versus thicker cast iron bollards. The ductility of cast steel gives the needed structural margin in the event of an overload situation.
- Grey Cast Iron is excellent corrosion resistant and cheaper per unit weight but the need for thicker wall sections and poor inferior mechanical performance such as low strength and low impact resistance make grey cast iron the last material for marine mooring bollards.
