When choosing a suitable bollard, engineers need to consider more than its nominal capacity. For example, mooring loads, material properties and structural design all influence product selection. Therefore, read our guide to mooring bollard load capacity, materials and design for further technical information.
Double Bitt Bollards for Marine Mooring Projects
Double Bitt Bollards are used at commercial ports, cargo terminals, harbours, docks and industrial jetties. Their twin-post configuration provides contact points for arranging mooring lines to suit the intended berth layout.
During product selection, engineers should consider mooring loads, line direction, mounting details and foundation strength. In addition, the final rated capacity and installation arrangement should be verified against the project design.

Marine Bollard Coating Technology
Marine bollards are exposed to moisture, salt and changing weather conditions. Therefore, a suitable protective coating system helps reduce corrosion and protect the external surface. The coating specification should also match the installation environment and project requirements.
Surface Preparation
Before coating, the surface is prepared to remove contaminants and support proper coating adhesion. The required preparation grade should follow the approved project specification.
Primer and Finish Coats
Primer and finishing coats form the protective coating system. Depending on the selected system and expected exposure conditions, the coating type and number of layers can be specified accordingly.
Dry Film Thickness
Total dry film thickness can be specified according to the agreed coating system. In addition, inspection requirements should be confirmed before production.
Coating Inspection
Quality checks may include surface condition, coating appearance and dry film thickness measurements. Further inspection can also be agreed according to project requirements.
