I. Product Function
1. A dedicated mooring device for docks, ports, and ship decks, used for winding and securing ropes. It restrains vessels during berthing, withstands the impact of wind, waves, and water currents, and prevents hull drifting and collision;
2. Suitable as a mooring and fixing component for inland river docks, coastal freight ports, yacht marinas, offshore drilling platforms, and various ship decks;
3. Can be supplied together with marine fasteners, marine watertight doors, marine piping systems, and complete port and vessel supporting products.

III. Material Application Scenarios
1. HT200 gray cast iron mooring bollards: suitable for small inland river docks and inland vessel decks, offering an economical option;
2. QT450 ductile iron mooring bollards: suitable for general coastal ports and medium-sized freight terminals, with good toughness and impact resistance;
3. Q235 cast steel mooring bollards: suitable for large seaports, ocean-going vessel decks, offshore platforms, and large-tonnage high-load working conditions.
IV. Product Advantages
1. Integrally cast with no spliced welds, providing high overall tensile and impact strength, and reducing the risk of fracture during large-tonnage mooring under strong wind and wave conditions;
2. The circular flange base features evenly distributed bolt holes, ensuring balanced force distribution, firm connection with the dock or deck foundation, and resistance to loosening;
3. The smooth curved horn surface reduces rope wear and breakage during winding, helping lower mooring rope loss;
4. The double-layer anti-corrosion coating resists seawater salt spray, rainwater, and rust, ensuring long service life for long-term outdoor use at coastal ports;
5. Tonnage specifications cover application needs from small yachts to ten-thousand-ton cargo vessel ports, and complete sets of high-strength marine fastening bolts can be supplied.
