Steel Cord Conveyor Belt Manufacturer

Steel Cord Conveyor Belt Manufacturer

Purposes: Extensive applications in coal,mining,port,metallurgy,power,chemical sectores for long-distance,large amount and high-speed conveyoring of materials.

Structure: The logitudinally uniformly arranged and left-right twisted zincifiaction steel cable and plastic core form the cord which is covered with rubber to form the belt.

Ensure the quality, in order to better explore the market, starting from the user’s needs, enhance scientific and technological content, the introduction of technology innovation, in order to put more quality products to the market, meet more machinery industry development, promote the further development of economy. In such a virtuous cycle to drive the conveyor belt into the industry with stronger momentum of sustained development!
