Because that corrosion of steel and reinforced concrete materials in the marine environment are not ever even and can’t last for many years, the most serious corrosion area is in splash zone, generally 0.3-0.5 mm per year, up to a maximum of 1 mm, about a full immersion zone of 3-10 times, resulting in China’s water industry marine dock construction serious corrosion.
Fiberglass material as a lightweight high-strength corrosion-resistant materials, which also has good thermal insultaion properties and dielectric properties, they have been used in marine construction in the decades ago. According to data reported, epoxy vinyl resin based fiberglass pultruded anti-corrosion lining, tank pipe, grille, the splash zone FRP coated cathode protection, pultrusion and winding FRP ribs and had entered port code table, offshore platform and a series of marine corrosion engineering.
For the atmosphere, water and the concentration of acid, alkali, salt, and a variety of oils and solvents, frp profiles have better resistance. They have been applied to various aspects of chemical anti-corrosion, is replacing carbon steel, stainless steel, wood, non-ferrous metals, etc.
