Steel Cord conveyor belts

With their proven high-performance and reliability, Steel Cord conveyor belts are among the most popular modes of material handling. Wrap wires are embedded inside rubber and the alternating right and left hand twisted wires facilitate the straight movement of the belts.
The cords used in Steel cord conveyors are made of specially developed high carbon steel. The cords are zinc-coated to ensure superior bonding between cord and rubber as well as to protect the same against corrosion.

Steel Cord Advantages:

High Tensile strength
Low elongation
Long life
High Efficiency
Very high adhesion between rubber and steel cord

Steel cord belts with breakers (transverse reinforcements)

Transverse reinforcements are additionally added between the cover and the layers of steel cord. It is because of increasing the capacity of withstanding impact loads and shocks and results in achieving an outstanding improvement in service life.
