Steel Cord Belts

Steel cord conveyor belts (ST) can convey bulk materials on long distances, under extremely difficult conditions. They are used primarily in the mining industry (quarries) to convey raw materials from the excavators to the discharge site, but they are also used in other fields of activity. A wide range of cover qualities is available.
