Titan2 Type UL LFMC is manufactured with a spiral wound strip of heavy gauge, corrosion-resistant, hot-dipped galvanized steel. The core is constructed with a square locked steel strip with an integral copper bonding strip enclosed within the steel convolutions. A rugged, flame retardant, flexible PVC jacket is extruded over the steel core. The gray jacket resists oils, mild acids and exposure to sunlight. Also available in other colors subject to minimum runs.
