Engineered for extreme tensile demands, high abrasive stress, chemical exposure, and temperature variances.
Founded in 2004 and operating within the state-of-the-art Rubber Industrial Park of Boye County (Baoding, Hebei Province), Hebei Boao Rubber Technology Co., Ltd. has developed into a premium global enterprise specializing in high-tension rubber conveyor belts and related bulk material conveying products. Under our premier registered brand "Jinao", we focus on researching, designing, and manufacturing high-performance conveyor systems that serve vital roles in national energy infrastructure and global industrial supply chains.
Strict Quality Assurance Standards: Equipped with an independent, state-certified physical properties laboratory and chemical analysis room, we guarantee continuous, real-time testing of rubber compounds, ply materials, and finished vulcanized belting. Our mandate remains absolute: no unqualified raw materials enter our processes, and no product exits our plant without meeting national and international compliance benchmarks.
From mining operations deep below the surface to high-heat metallurgical plants and dusty cement facilities, Boao belts are optimized for specific industrial challenges.
Designed for extreme high-heat environments handling sinter, coke, and slag. Our heat-resistant lines withstand continuous material temperatures up to 250°C and peak temperatures up to 400°C, preventing surface cracking and premature ply separation.
Utilizing high-tensile steel cord and nylon/polyester (EP) carcass structures, our belts handle heavy impact, deep troughing angles, and sharp rock transitions in large coal mines, gold, and copper processing facilities.
Providing custom pipe conveyor systems and high-angle chevron belts that prevent material spillage, reduce dust pollution, and resist environmental oxidation and ozone degradation in marine shipping installations.

| Belting Type | Carcass Construction | Tensile Strength Range | Abrasion Resistance | Special Properties / Ideal Environment |
|---|---|---|---|---|
| Nylon (NN) Series | Nylon 66 / Nylon 66 Plies | 100 - 630 N/mm per ply | ≤ 90 mm³ (DIN ISO 4649) | High flexibility, superior impact absorption, ideal for long-distance bulk conveying. |
| Polyester (EP) Series | Polyester Warp / Nylon Weft | 100 - 800 N/mm per ply | ≤ 120 mm³ (DIN ISO 4649) | Low elongation, high dimensional stability, ideal for mid-to-long distance logistics. |
| Steel Cord (ST) Series | Zinc-coated high-tensile steel cords | ST630 - ST5400 | ≤ 80 mm³ (Premium DIN W) | Near-zero elongation under maximum load, designed for high-tonnage mining veins. |
| Flame Retardant Series | EP/Steel Core with SBR/NBR blend | 315 - 3150 N/mm | ≤ 140 mm³ | Self-extinguishing cover, complies with MSHA & ISO 340 anti-static and safety standards. |
| Heat Resistant (HR/EHR) | EP/Glass-fiber reinforced fabric | 200 - 2000 N/mm | ≤ 110 mm³ | Resists vulcanized cracking, thermal fatigue up to 250°C continuous processing. |
At Hebei Boao, quality control isn't a mere final checklist; it is integrated directly into the polymer synthesis phase. Our internal laboratory features sophisticated analysis equipment to test physical properties under dynamic stress. Our testing protocols include:
Boye County, situated in Hebei Province, represents China's largest industrial rubber cluster. This unique manufacturing ecosystem gives Hebei Boao structural advantages that we pass directly to our global partners.
By operating inside the Rubber Industrial Park, we are located alongside premier chemical, nylon fabric, and steel wire suppliers. This localized ecosystem reduces raw material logistics costs and ensures rapid component acquisition.
Spanning over 30 acres, our factory handles large-scale runs alongside custom engineered solutions. Equipped with automated calendering, continuous vulcanizers, and computerized mixing stations, we guarantee uniform rubber thickness and ply tension.
Through advanced automation, energy-efficient vulcanization lines, and local raw materials procurement, we provide flat rubber belting options that meet strict international ISO/DIN standards at highly competitive pricing.
Our Jinao brand products have been deployed across major national and international heavy industrial operations, validating our structural durability under extreme workloads.
We believe in establishing long-term service agreements that keep your systems operating smoothly. From initial layout design to on-site vulcanized splicing, our technicians support your operational team through every phase of the belting lifecycle.
Emergency Repair Response: 24/7 technical consultation channels for splicing failures, mechanical tears, and pulley tracking troubleshooting.
Preventative Inspection Protocols: Periodic thickness profiling, belt wear calculations, joint condition checks, and cover compound health reports.
Optimized Safety Stocks: We coordinate with global partners to warehouse critical spares, ensuring minimal downtime in the event of unforeseen conveyor blockages or failures.
Certified Global Quality Compliance:
Compliance Standards: API 6D, API 607, CE, ISO9001, ISO14001, ISO18001
