Steel Cord Rubber Conveyor Belts Manufacturer

Steel cord conveyor belts use high-strength steel wire ropes as their internal framework. This structure gives the conveyor belt extremely high tensile strength and wear resistance, ensuring long-lasting durability even in harsh environments. Rentone Belt offers steel-cord conveyor belts in various strength grades, including ST-500, ST-630, ST-800, ST-1000, ST-1250, ST-2500, and ST-4500. Fire-resistant steel cord conveyor belts possess the advantages of ordinary steel cord conveyor belts, such as long-distance and heavy-load capabilities, while also offering fire resistance and anti-static properties, making them suitable for material handling in underground coal mines. Steel cord conveyor belts play a vital role in heavy industries such as coal mining, metallurgy, and chemical industries, as well as in logistics hubs like ports and docks.

Our company’s steel cord conveyor belts can be customized according to customer needs and are available in various wear-resistant, tear-resistant, oil-resistant, and fire-resistant grades. Widths range from 500 mm to 1600 mm.

High Tensile Strength
The conveyor belt uses steel cords as its framework, providing excellent tensile strength, making it suitable for long-distance heavy material conveying, with high load capacity and no deformation.
Excellent Impact and Tear Resistance
The steel cords are resistant to tearing and punctures, able to withstand harsh environments and the impact energy of sharp objects, making them the best choice for transporting raw ore and stone materials in mines.
Minimum Elongation
Compared to fabric conveyor belts, steel cord conveyor belts have very low elongation, ensuring stable operation and smooth material conveying.
Long Service Life
The steel cord core is not easily damaged, extending service life and reducing maintenance costs in harsh environments (high loads, large drops, long distances).
Good Troughing
The steel cords are arranged longitudinally without a transverse framework, making it easy to form an ideal deep trough and allowing the carrying of more material while preventing spillage.
Fire and Heat Resistance
Steel cord conveyor belts can be customized with fire and heat-resistant properties, making them ideal for use in extreme environmental conditions, commonly found in the coal mining and steel manufacturing industries.
Long Joint Life and High Reliability
Steel cord conveyor belts use vulcanized joints, and the joint strength can exceed 90% of the conveyor belt strength, thereby extending service life.
