Explore our industrial-grade, high-durability conveyor belts designed for extreme operational environments.
In modern industrial bulk logistics, optimizing vertical and curvilinear paths represents one of the most significant engineering challenges. Traditional linear conveyor layouts often require vast spatial footprints and multi-stage transfer points, which drastically increase material degradation, dust emission, energy consumption, and equipment wear. Fan-shaped patterned conveyor belts have emerged as the premier engineering solution for navigating complex structural curves and steep inclines.
By integrating specialized transverse rigidity, custom molded rubber patterns, and variable carcass dynamics, modern curved belts maintain stable centering forces even on tight horizontal and vertical radii. The technical development of these systems relies on sophisticated material science and mechanical modeling to address the complex physical forces encountered in high-load bulk handling operations.
"By eliminating transfer towers and optimizing vertical-to-horizontal curve transitions, industrial operators can expect up to a 30% reduction in system energy requirements and a 45% decrease in mechanical wear points."
The next era of conveyor belt manufacturing focuses on digital integration and eco-friendly polymer formulation:
Founded in 2004, the Jinao® brand represents global excellence in conveyor system engineering, research, and manufacturing.
Located in the prestigious Rubber Industrial Park of Boye County, Baoding, Hebei Province, Hebei Boao Rubber Technology Co., Ltd. spans over 30 acres of state-of-the-art production facilities. Over the past 22 years, our "Jinao" brand has become synonymous with durability, innovation, and precise engineering.
As a fully integrated designer and manufacturer, we oversee the entire value chain—from compounding raw elastomers to final vulcanization and dynamic test runs. Our advanced facility features modern rolling mills, high-capacity forming machines, giant vulcanizing presses, and a comprehensive raw material and finished product testing laboratory.
Industrial performance depends on reliable quality control. Here is how we guarantee standard compliance.
Our independent chemical analysis rooms and physics testing laboratories monitor every stage of production. From raw rubber inspection to polymer rheology and finished belt tensile testing, we enforce a zero-defect policy.
With an array of state-of-the-art testing tools, our senior QA team validates flame resistance, abrasion metrics, temperature thresholds, and tensile parameters to meet global certifications.
Backed by strong engineering expertise and an active global support team, Jinao® products operate reliably in major steel mills, coal mines, cement plants, and ports across China and worldwide.
Custom-engineered rubber belts built for specific industrial environments, mechanical loads, and chemical requirements.
High tear-resistant and anti-impact conveyor belts designed to move heavy ores, granite, and coal across steep underground or surface mines.
Heat-resistant conveyor belts engineered to withstand materials up to 300°C (such as hot sinter, coke, and slag) without compound hardening.
High-angle wavy edge and patterned belts that transport abrasive sand, gravel, clinker, and fine powders without material fallback.
Acid-and-alkali resistant rubber compounds that resist chemical swelling, cracking, or deterioration when exposed to highly reactive raw materials.
Continuous, high-capacity conveyor belts resistant to extreme weather, salt spray, and ozone, offering high-throughput cargo vessel loading.

Integrating advanced automation into rubber vulcanization and processing lines is key to producing highly reliable conveyor belts. In our Boye County facility, Hebei Boao Rubber Technology uses advanced technology to control pressure, temperature, and curing time.
By automating our mixing and calendering workflows, we achieve consistent vulcanization across every meter of the belt. This manufacturing precision improves adhesion between the rubber covers and fabric plies, reducing the risk of ply separation and belt failure.
As a direct factory manufacturer, we maintain strong vertical integration. We source raw materials directly, compound our own rubber, and handle logistics through major domestic ports. This direct control minimizes supply chain disruptions and ensures reliable lead times for our global industrial partners.
Use the technical reference below to select the appropriate belt carcass and grade for your operations:
| Carcass Type | Standard Reference | Tensile Strength (N/mm) | Elongation at Break | Key Performance Features |
|---|---|---|---|---|
| Nylon (NN) | GB/T 7984-2013 / DIN 22102 | 100 - 630 N/mm per ply | ≤ 4.0% | High elasticity, excellent fatigue resistance, high impact strength. |
| Polyester (EP) | ISO 14890 / DIN 22102 | 100 - 800 N/mm per ply | ≤ 1.5% (low stretch) | Excellent dimensional stability, high humidity resistance. |
| Steel Cord | DIN 22131 / EN ISO 15236 | ST 500 - ST 5400 | ≤ 0.25% | Extremely low elongation, suitable for long-distance, high-capacity lines. |
| Patterned (Chevron) | Factory Std / DIN 22102 | EP/NN Multi-ply reinforced | ≤ 2.0% | Slip-resistant profile, supports inclines up to 40 degrees. |
