The materials of navigation marks mainly include the following:
Steel: Steel has high strength, but it is easy to rust, so it needs regular maintenance.
Fiberglass: Fiberglass is not easy to degrade and is suitable for specific environments.
Aluminum alloy: Aluminum alloy is light and strong, and it is also environmentally friendly.
Polymer polyethylene plastic: This material is corrosion-resistant and recyclable, and is widely used in navigation mark production.
Polyethylene (PE): PE material has the characteristics of light weight, corrosion resistance, impact resistance and good weather resistance, and is often used in plastic navigation marks.
Polystyrene foam material: This material is used as the internal buffer medium of navigation marks used in offshore construction.
