Mooring Bollard General Introduction
The normal used material for mooring bollards is cast steel, ductile cast iron and stainless steel. Ductile cast iron is our first choice for its high corrosion resistance and high tensile strength which can save much time and cost in maintaining.
Bollards designed by GLEN have a safety factor 1.5-3 times than working load.
All bollards are well painted with epoxy primer &middle coat, and polyurethane topcoat against corrosion.
