Premium wear-resistant, flame-retardant, and steel-reinforced conveyor belt selections engineered for demanding bulk transport applications.
A detailed analysis of Steel Cord Conveyor technology, material compositions, selection criteria, and operational optimization.
Unlike fabric-reinforced belts, steel cord rubber conveyor belts utilize high-tensile, zinc-galvanized steel cords arranged longitudinally as the main carcass. This core configuration offers exceptional tensile strength (up to ST5400) with extremely low elongation. Surrounding these high-tensile cables is an adhesion-promoting core rubber formulation, wrapped inside specialized top and bottom protective rubber covers. This construction handles extreme loads, long span distances, and severe impacts.
Modern formulations target customized wear profiles: abrasion resistance for abrasive ores, self-extinguishing flame retardancy for coal terminals, thermal insulation for hot sinter plants, and flex-cracking resistance for low temperatures. By integrating premium polymers and carbon black structures, our engineers maximize cover life while reducing rolling resistance, which lowers operational power consumption.
To prevent costly downtime, advanced steel cord conveyor systems integrate modern active protection components. These include cross-rigid reinforcing breakers to counter longitudinal tears, alongside steel sensor loops embedded directly in the cover rubber. These sensors communicate with real-time electronic diagnostic systems to trigger emergency stops in the event of foreign body penetration.
| Performance Indicator | Steel Cord Rubber Belt (ST Series) | Fabric Conveyor Belt (EP / NN Series) | Direct Operational Benefit |
|---|---|---|---|
| Ultimate Tensile Rating | Extreme: ST500 up to ST5400 N/mm | Medium: Up to 3150 N/mm (multi-ply) | Enables single-flight long-distance transport |
| Elastic Elongation | Extremely Low (typically < 0.2% max) | Moderate (1.5% to 2.5% elongation) | Reduces take-up stroke requirements drastically |
| Troughability (DIN/ISO) | Excellent deep trough (up to 45° angle) | Standard trough (30° - 35° typical limit) | Increases volumetric carrying capacity without spills |
| Splice Efficiency | Up to 100% of basic belt strength (vulcanized) | 60% - 80% maximum splice efficiency | High reliability under extreme operating stress |
| Rip Resistance | High (integrates steel transverse breakers) | Medium (subject to localized puncture tears) | Minimizes risk of catastrophic longitudinal failure |
Established in 2004 and situated inside the Boye County Rubber Industrial Park, Baoding City, Hebei Province, Hebei Boao Rubber Technology Co., Ltd. spans an expansive state-of-the-art manufacturing campus of over 30 acres. Utilizing our flagship brand "Jinao", we are a professional manufacturer in China that integrates product development, research, design, manufacturing, and business services for conveyor belts and conveyor machinery accessories.
Boao operates multiple advanced processing lines covering rolling, extrusion, shaping, vulcanization, and material testing. Our commitment to high quality standards is reflected in our ISO international quality management system certification. Our production capability encompasses standard, heat-resistant, oil-resistant, acid-alkali resistant, cold-resistant, and high-tensile steel wire rope core conveyor systems, providing reliable material handling solutions globally.










How Hebei Boao utilizes the regional cluster dynamics and vertical integration to provide competitive advantages for global buyers.
Our in-house chemical analysis room and physical testing laboratories monitor every stage of production. From raw polymer inspection to finished steel cord adhesion tests, we operate under a strict policy: unqualified raw materials are rejected, and products that do not meet standards are not released for shipment.
Based in the Boye County Rubber Industrial Park, we benefit from a highly developed local cluster. This provides immediate access to premium raw materials, tooling machinery, and technical research support. This close proximity helps reduce raw material freight and logistics expenses, translating directly into pricing advantages for our clients.
Our strategic location in northern China offers direct transport routes to Tianjin port. This facilitates efficient packing, export customs clearance, and secure ocean freight container loading for key international markets in Europe, the Americas, Australia, and Southeast Asia.
We manufacture a complete line of high-performance conveyor belting, heavy-duty rollers, and mechanical accessories.
Custom engineered belting solutions matching standard, fire-resistant, high-temperature, acid-alkali resistant, and cold-resistant operational demands:
Durable components designed to prolong system lifecycle and maintain correct tracking alignment:
Comprehensive lifecycle support to maximize conveyor performance and reduce consumption costs:

Our manufacturing processes are certified to meet strict global safety and quality assurance criteria.
Empowering major infrastructure projects, steel complexes, cement plants, and extraction mines with reliable handling systems.
For procurement directors, engineering heads, and supply managers looking to secure reliable sourcing partners.
Ensure your supplier complies with global standards (DIN 22131, ISO 15236, AS 1333, etc.). Check that the rubber grade matches your specific application: Grade X/Y for general wear, Grade W for extreme abrasion, and Grade F/K for flame-retardant needs.
The connection strength between the steel wire core and the surrounding tie-gum determines the belt's lifespan. Ask for pull-out test reports in N/mm. Lower adhesion values increase the risk of internal cord separation under stress.
Evaluate your purchasing decisions on Total Cost of Ownership (TCO) rather than just the initial price tag. High-quality steel cord rubber belts reduce splice maintenance frequency, lower power consumption, and extend continuous runtime.
