Steel Cord Conveyor Belts

Compared to textile conveyor belts, these belts have higher tensile strength, lower elongation, and superior impact resistance. Steel cord conveyor belts are designed for heavy-mining purposes and the transportation of bulk material over long distances.

With one of the best production lines in the world, Vasco steel cord belts are known for an excellent wear resistance as well as low elongation. Following customer requirements Vasco steel cord belts can be produced to any interna-tional standard; most common DIN22131, EN ISO 15236, SANS1366 and AS1333. An even better adhesion and prevention of rusting as well as chemical corrosion – and therefore longer service life – is achieved due to the open structure of steel wires, which allows the rubber to be completely soaked into the gap between the steel wires during vulcanization.

Clients can choose from a wide range of cover rubber compounds, such as low abrasive, standard, fire resistant, flame resistant, heat resistant, cold resistant and many more. Vasco also offers additional steel cord or textile break-ers in different qualities to protect the steel cord conveyor belt even more.

Vasco’s steel cord conveyor belts are mainly used in the coal mining industry, ports, quarries, cement and power plants.
