Product Description
1. Buoy body materials
Metal: stainless steel (highly corrosion-resistant, for large buoys), aluminum alloy (lightweight, suitable for small and medium-sized buoys).
Polymer materials: high-density polyethylene (PE, good weather resistance, low cost, wide application), polypropylene (PP, high temperature resistance, suitable for tropical seas), FRP (FRP, high strength, moldable, used in science/weather buoys).
Auxiliary material: polyurethane foam (internal buoyancy filling for enhanced safety).
2. Anchor material
Chain: High strength alloy steel (tensile resistance, corrosion resistance, for shallow / medium and deep water).
Ropes: ultra-high molecular weight polyethylene (UHMWPE, mainstream, high strength, lightweight and corrosion resistance), steel wire cables (for deep seas, extremely strong but prone to rust).
Anchor body: cast iron or concrete (heavy weight, fixed to the seabed).
3. Electronic systems and accessories
Housing: stainless steel, engineering plastic (waterproof and anti-corrosion).
Seals: sealing rings such as fluoroelastomers (to prevent seawater infiltration).
Wire: Salt spray resistant insulated wire (to ensure circuit stability).
Core material selection principles: give priority to meeting the needs of corrosion resistance, strength and buoyancy, and take into account cost and environmental adaptability.
