China Belt Steel Cord Manufacturer & Supplier

Pioneering High-Tensile Steel Wire Rope Reinforcements & Engineered Conveyor Solutions for Global Heavy Industry

The Global Industrial Landscape of Steel Cord Belting

In modern high-capacity logistics and mining infrastructure, steel cord conveyor belts represent the peak of bulk handling capability. Heavy industries are operating at unprecedented scales, requiring systems that can transport massive tonnages across challenging topography, over miles of mountainous or underground environments. Steel cord core design provides the extremely high tensile strength and minimal structural elongation necessary for these operations.

Global demand continues to grow in mineral extraction (iron ore, copper, gold), bulk shipping ports, coal-fired power plants, and modern dry-process cement facilities. These applications require dynamic strength, impact resistance, and long-term durability. Traditional fabric ply belts can experience elongation and splice failures over long distances, whereas steel wire rope reinforcement provides reliable operational continuity under high mechanical tension.

Why Choose Boao Technology?

Technical expertise and strict quality control systems at the core of our operations

Quality Assurance

Our facility features an independent chemical analysis laboratory and physical testing facility. We monitor key points from raw material selection to final vulcanization and curing. Materials that do not meet specification are not processed, and finished products undergo testing before shipping.

Strict Quality Control

Our quality control program utilizes trained technicians and testing equipment to evaluate mechanical performance parameters. We run tests for steel cord adhesion, cover compound abrasion resistance (DIN standard limits), and tensile strength retention after aging.

National & Global Reach

Supported by engineering services and post-sales support networks, our products are distributed across industrial centers in China and international markets. Our conveyor belts and components are used in steel manufacturing, metallurgy, underground coal mining, cement works, power stations, ports, and fertilizer storage sites.

Advanced Curing & Vulcanization Technology

Our vulcanization process integrates heat and pressure control to achieve consistent properties. For steel cord belts, maintaining precise alignment and uniform tension of individual wire ropes during the rubber injection and curing stage is critical. Our production equipment manages this process, which helps prevent tracking issues, belt distortion, and uneven stress distribution under heavy loads.

Frequently Asked Questions & Technical Resource

Expert technical insights regarding selection, installation, and operation of steel cord and fabric rubber belts

What are the main advantages of steel cord conveyor belts compared to multi-ply fabric belts?
Steel cord conveyor belts provide high tensile strength and minimal elongation during operation. They are suitable for high-tension, long-distance overland conveying where fabric reinforcement (like EP or NN) may stretch too much. The steel wire cores also offer high impact resistance and allow for larger troughing angles due to their structural characteristics.
How does Hebei Boao ensure zinc-galvanized steel cords adhere properly to the surrounding rubber core?
We use zinc-galvanized steel wire ropes which are combined with specialized chemical bonding agents in our rubber cover recipe. During the vulcanization process under controlled heat and pressure, a chemical bond is formed between the zinc-plated wire surface and the customized rubber matrix. This bond helps prevent separation and protects the steel cores from moisture and corrosion.
Which international testing standards do Boao's conveyor belts comply with?
Our products are manufactured and tested in accordance with common international standards, including DIN 22131 (German Standard for steel cord conveyor belts), ISO 15236, AS 1333 (Australian Standard), and national GB standards. Our laboratory tests cover tensile strength, elongation at break, rubber cover abrasion loss (measured in cubic millimeters), and post-aging properties.
How are splice joints designed and executed for high-tension steel cord belts?
For steel cord belts, splicing is done using hot vulcanization in a multi-stage step pattern. The rubber cover is stripped, and the individual steel cords are laid out and interlocked without overlapping in a specified pattern, separated by specialized tie-gum rubber. Heat and high-pressure vulc-presses are then applied to reform the continuous structure, ensuring the splice matches the strength requirements of the original belt.
Can Boao supply custom dimensions for conveyor idler roller brackets and frame structures?
Yes. Our engineering division designs and fabricates support components to order. We produce custom bracket frames, trough idlers, self-aligning trainer idler brackets, and impact cradle setups to fit specific structural designs and belt widths from 500mm up to 2200mm.
How does flame retardant compounding work in rubber conveyor belts?
Our flame-retardant conveyor belts are compounded using flame-suppressing additives (such as chlorinated paraffins, antimony trioxide, or aluminum trihydroxide) integrated into the base polymer (SBR, NBR, or Neoprene). This formulation helps the belt self-extinguish when the heat source is removed, meeting safety standards like EN ISO 340 and MSHA requirements for underground mining.
