Grade R4 Mooring Chain

Grade R4 mooring chain finds extensive use in various offshore applications due to its superior strength, durability, and resistance to corrosion.Grade R4 mooring chains are utilized to secure offshore oil and gas platforms in place. These platforms operate in harsh marine environments and require robust mooring systems to withstand the forces exerted by waves, currents, and wind. The high tensile strength and corrosion resistance of Grade R4 chains make them ideal for this purpose.
