Rubber Conveyor Belts - Steel Cord
Our steel cord rubber conveyor belts are designed for high-tension, heavy-duty applications requiring strength, stability, and reliability. Reinforced with galvanised steel cords and premium rubber compounds, they provide low elongation, high tensile strength, and excellent resistance to impact, tearing, and wear for long-distance bulk material transport.

Optional Rip Protection
Installed between the top cover and steel cords, this reinforcement layer absorbs impact energy and improves resistance to punctures and slitting. It also helps prevent tears from propagating along the belt while maintaining flexibility and troughability.
Rubberised steel cord strips embedded transversely at regular intervals strengthen the belt against tearing caused by trapped materials or chute impact, helping to reduce the risk of catastrophic belt failure.
