250KN Tee Type Cast Iron Boat Bollard T Head Bollard Galvanized Mooring Protection

Material and Manufacturing

● Cast Iron: HT200 gray cast iron is mainly used as the main material. It has good strength, wear resistance, and shock absorption properties. It can withstand the tension and impact force when a ship is moored, has excellent casting performance, can be made into complex shapes, has a relatively low cost, and is suitable for mass production.

● Steel: High - strength steel such as Q345 is often used for the anchor rods. It can be firmly connected to the cast - iron main body and effectively transfer external forces to the basic structure. For nuts and washers, common carbon steel or stainless steel can be selected. Common carbon steel has a low cost, while stainless steel has good corrosion resistance.

● Other Materials: Materials such as asphalt and fibers are generally used as the core filler. They play a role in sealing and buffering, reducing the friction between the mooring rope and the bollard, and preventing water and impurities from entering.

● Mold Making: Corresponding casting molds are made according to the design dimensions and shapes of T - shaped cast - iron mooring bollards. Molds can be made of wood, metal, plastic, etc., and the commonly used process is the lost - foam process. In the lost - foam process, a model with the same shape and size as the casting is made of foam plastic. A refractory coating is applied to the surface of the model, which is then dried and formed with dry sand. Subsequently, molten metal is poured. Under high temperature, the foam - plastic model gasifies and disappears, and the molten metal takes its place. After cooling and solidifying, the casting is formed.

● Melting: The selected cast - iron materials are put into a furnace, such as a cupola furnace or an electric furnace, for melting. During the melting process, parameters such as temperature and chemical composition must be strictly controlled to ensure that the quality of the molten iron meets the casting requirements. The properties of the cast iron are adjusted by adding corresponding alloying elements and inoculants.

● Pouring: When the molten iron reaches the specified temperature and composition after melting, it is poured into the pre - prepared mold. During the pouring process, the pouring speed and quantity should be well - controlled to avoid defects such as misruns, gas pores, and slag inclusions.

● Surface Treatment - Long - lasting Protection: To enhance the corrosion resistance of the mooring bollard, either hot - dip galvanizing or spraying high - performance anti - rust paint is adopted. The zinc layer formed by hot - dip galvanizing adheres tightly, effectively isolating air and moisture. The anti - rust paint provides double protection, extending the service life of the product in harsh marine environments.

1. Solid Material: Carefully selected high-quality cast iron features a dense and firm texture. It can resist powerful external forces and withstand the strong pulling forces generated during ship mooring under various complex conditions, providing reliable support for ship docking.

2. Exquisite Craftsmanship: Advanced casting techniques are adopted. The surface of the casting is smooth, and the internal structure is uniform without defects such as sand holes and air holes. This ensures stable product quality, and the overall performance far exceeds that of mooring bollards manufactured by ordinary processes.

3. High Adaptability: The unique T-shaped design is suitable for various ship sizes and cable specifications. Whether it is a large cargo ship or a small fishing boat, safe mooring can be achieved through reasonable mooring methods.

4. Convenient Installation: The design fully takes into account the actual installation scenarios. With a simple structure and easy installation process, no complex installation tools or professional skills are required. It can effectively shorten the installation time and reduce construction costs.

Application Scenarios:

1. Commercial Ports: Container ships and oil tankers frequently enter and exit. The T-shaped cast iron mooring bollards can withstand huge pulling forces, ensuring that ships dock stably during loading and unloading operations, guaranteeing the efficient operation of the port, and meeting the needs of commercial transportation.

2. Yacht Marinas: For yachts that pursue a delicate docking experience, the mooring bollards are not only exquisitely designed but also stable. The T-shaped design enables crew members to easily tie the mooring ropes, allowing yachts to berth safely and providing reliable support for recreational boating activities.

3. Military Ports: Military vessels need to dock quickly and safely. The mooring bollards are high in strength and impact-resistant, capable of withstanding the great force when military ships berth, meeting the high standards of military operations, and performing excellently in both special missions and daily dockings.

4. Inland River Ports: Inland river vessels are diverse in types, and the water levels change greatly. The T-shaped cast iron mooring bollards are corrosion-resistant and highly adaptable, able to secure vessels under different water level conditions and facilitating the smooth progress of inland river shipping.
