GBT554-2008 Marine Double Cross Bollard Type DL
Introduction:
GBT554-2008 Marine Double Cross Bollard Type DL is a type of bollard that is commonly used in marine environments. It is designed to provide a secure mooring point for ships, boats, and other vessels. The bollard is made of high-strength materials such as cast iron or cast steel, which enables it to withstand the forces exerted by the moored vessel.
The bollard consists of two cross-shaped horns that are placed perpendicular to each other. These horns provide two separate points of contact for the mooring rope, which improves the stability of the moored vessel. The bollard is also designed with a circular base that is securely attached to the dock or pier.
