350KN T Type Cast Iron HT200 Port Bollard Dock Bollards Galvanized Marine Boat Ship Shore

Material and Manufacturing

● Cast Iron: Generally, HT200 gray cast iron is selected. It has excellent casting properties, shock absorption, and wear resistance, enabling it to withstand the tensile force and impact when mooring ships. In some cases, ductile iron is also used. Ductile iron has higher strength and toughness than gray cast iron, which can extend the service life and reliability of the T - shaped cast - iron bollard.

● Anchor Bolts and Connecting Components: Anchor bolts usually adopt high - strength steel, such as Q345, etc., to ensure the connection strength with the wharf foundation. Nuts, washers, etc. generally use ordinary carbon steel or stainless steel to prevent rust and corrosion and ensure the long - term stability of the connection.

● Core Filler: Elastic materials such as rubber and polyurethane can be used as the core filler. When mooring ships, it can play a buffering role, protect the mooring ropes from wear, and also reduce the collision force between the ship and the bollard.

● Mold Making: Based on the design dimensions and shape of the T - shaped cast - iron bollard, materials such as wood, metal, or plastic are used to make the mold. For mass production, metal molds are often employed. These metal molds have high precision and strong durability, ensuring the dimensional accuracy and surface quality of the castings.

● Casting Process: Processes like sand casting or lost - foam casting are adopted. In sand casting, the prepared molding sand is filled into the mold, compacted, and then the mold is removed to form the casting cavity. In lost - foam casting, a foam plastic model is first made, coated with refractory materials, and then buried in dry sand. When pouring, the foam plastic model gasifies and disappears, and the molten metal fills the cavity. The molten cast - iron liquid is heated to an appropriate temperature, generally around 1400℃ - 1500℃, and then poured into the casting cavity. After cooling and solidifying, the blank of the T - shaped cast - iron bollard is formed.

● Machining: The blank is first rough - machined to remove excess burrs, flash, etc., leaving a margin for subsequent finishing. Then, finishing operations are carried out, including grinding and polishing the surface of the bollard to achieve the surface roughness and dimensional accuracy required by the design. Precise machining is performed on the installation holes, connection parts, etc., to ensure the fitting accuracy with components such as anchor rods and nuts.

● Surface Treatment: Surface treatment methods such as hot - dip galvanizing and spraying anti - corrosion paint are used. Hot - dip galvanizing can form a dense zinc layer on the surface of the bollard, effectively preventing the corrosion of cast iron by seawater, air, etc. Spraying anti - corrosion paint can further improve its corrosion resistance. Also, different colors of paint can be selected according to needs, serving the functions of aesthetics and identification.

1, High Load-bearing Capacity: Made of cast iron material, such as HT200, it has high strength and can withstand the large pulling force generated during the mooring of ships. It can meet the mooring force requirements of different specifications ranging from 50KN to 2000KN, ensuring the safety of ships during operations such as berthing and shifting.

2, Long-lasting Durability: The cast iron material itself has good wear resistance and fatigue resistance. During long-term use, it can withstand the friction of mooring ropes and the erosion of the natural environment, and is not prone to damage, thus having a long service life.

3, Corrosion resistance: The surface of the cast iron mooring bollard is usually treated with anti-rust measures, such as applying anti-rust paint or other anti-corrosion coatings. This can effectively resist corrosive substances in the natural environment like seawater and sea breeze, reduce the risk of rust and corrosion, and extend the service life of the mooring bollard.

4, Less maintenance cost: Due to its good durability and corrosion resistance, under normal use, there is no need for frequent maintenance and replacement, thus reducing the later maintenance cost.
