The Differences Between the Three Materials for Making Dock Bollard
Dock bollards are crucial elements in marine infrastructure, providing mooring points for vessels. They are typically made from Ductile Iron Grey Cast Iron Cast Steel materials, each with its own set of advantages and disadvantages. We compare the materials based on their strength, impact resistance, ductility, corrosion resistance, and price.
Overview
Ductile Iron
Strength:The strongest of the three materials
Impact Resistance:Better impact resistance
Ductility:Is a ductile material
Corrosion Eesistance:High corrosion resistance
Price：The most expensive of the three materials
Grey Cast Iron
Strength:Less intense
Impact Resistance:Lower impact resistance
Ductility:Brittle materials
Corrosion Eesistance:Best corrosion resistance
Price：Cheapest price
Cast Steel
Strength:High impact resistance
Impact Resistance:High strength
Ductility:Brittle materials
Corrosion Eesistance:Requires regular maintenance to prevent corrosion
Price：Medium price
Summarize
When choosing the material for dock bollards, factors such as the expected loads, environmental conditions, maintenance requirements, and budget should be considered to. ensure optimal performance and longevity.
