Marine-related components (ship equipment, marine facilities, etc.)
Features
Once at sea, marine components are constantly exposed to sunlight and seawater until they enter the dock of their respective countries.
Once at sea, marine components are constantly exposed to sunlight and seawater until they enter the dock in each country.Therefore, high corrosion and weather resistance is required.
Application
Marine Related Components ー Lights for ships, buoys for navigation, etc.
