Steel Cord-type constructions utilize a single layer of uniformly tensioned steel cords as tension members, encased in rubber. Steel cord belts are generally found in high tension and/or long distance applications and/or where extremely low stretch is a necessity. These tensions typically range from ST500 kN/m to ST5400kN/m and up. Typical elongation for steel cord conveyor belting is less than 0.25 %.
Steel cord belts must be manufactured to width. There are mainly two different types of cords. One is a 7x7 cord for low to mid tension and the other is a 7x19 cord for mid to high tension. These two types of cord enable rubber to fully penetrate to the center core. If rubber doesn’t penetrate to the core, the cord may corrode from small cuts or at the belt ends.
