Marine-grade materials are specially designed to withstand the harsh conditions found in marine environments. These materials are resistant to saltwater, humidity, and UV radiation, making them ideal for use in boats, docks, and other structures exposed to the sea. Common examples include stainless steel, marine plywood, and specific types of plastics. Using marine-grade materials helps prevent corrosion, decay, and other forms of damage that can occur when regular materials are used in marine settings. This durability ensures longer lifespans and reduced maintenance costs for products like boats, furniture, and equipment used in coastal areas.
