Explore Specifications →Located in the heart of the Boye County Rubber Industrial Park, Baoding, Hebei Province, Hebei Boao Rubber Technology Co., Ltd. (Jinao brand) has grown into a world-class bulk material conveying system manufacturer since its establishment in 2004. Boasting custom-designed advanced vulcanization systems, state-of-the-art calendering machinery, and raw material chemical formulation checking labs, Boao provides highly tailored material solutions to mining and industrial clusters globally, with a sharp focus on the rapidly developing Indonesian and Southeast Asian infrastructure sectors.
As the primary logistical gateway and economic heart of Indonesia, the Greater Jakarta Area (Jabodetabek) manages massive volumes of bulk materials, ranging from cement, sand, and aggregate required for extensive urban construction to coal supplies powering regional electrification networks. The expanding Port of Tanjung Priok and the industrial centers in Bekasi, Karawang, and Tangerang require transport networks that maximize throughput while managing structural constraints.
Standard flat rubber conveyor belts generally reach their slippage limit at incline angles between 15° and 18°. When transporting wet sand, run-of-mine aggregates, or volcanic materials common to West Java, materials inevitably roll back, causing critical machinery downtime, material losses, and safety hazards. Chevron patterns—specifically designed in herringbone, open V, closed V, and multi-ridge structures—create natural barrier walls to lock materials in place. For Jakarta's maritime unloading docks and cement batching plants, where land costs are high, deploying Chevron profiles allows engineers to reduce conveyor frame lengths by up to 50% compared to traditional flat conveyor runs.
Jakarta’s industrial environment features unique conditions: humidity levels consistently exceeding 80%, high ambient temperatures (average 32°C), and exposure to high levels of rainfall. These conditions lead to quick hydrolysis in lower-grade rubber compounds and cause mold and fiber rot in poor quality reinforcement fabrics. Boao Jinao Chevron Conveyor Belting utilizes synthetic Polyester (EP) and Polyamide (NN) fabric cores, treated with anti-humidity coatings, combined with high-grade EPDM and SBR cover rubber. This formulation ensures that our belts avoid ply separation, resist UV cracking, and maintain elasticity under Jakarta’s intense sun and monsoon rains.
| Chevron Profile Pattern | Standard Cleat Heights | Maximum Incline Angle | Typical Jakarta Industry Application |
|---|---|---|---|
| Closed V-Shape (Herringbone) | 15mm, 25mm, 32mm | Up to 35° | Aggregate Handling, Sand Processing, Cement Clinker |
| Open V-Shape Pattern | 15mm, 25mm | Up to 30° | Agricultural Feeds, Bulk Grain Terminals, Crushed Ore |
| High-Cleat Special Profile | 32mm, 50mm | 35° to 45° | Deep Mining Shafts, Ship Unloading in Tanjung Priok |
| U-Shape / Multi-Ridge Pattern | 10mm, 15mm | Up to 28° | FGD Gypsum, Fine Coal Powder, Fertilizers |
Modern material logistics require more than just a rubber sheet; they demand complete engineering integration. Hebei Boao Rubber Technology offers complete conveyor support lines designed to match the mechanical requirements of Chevron conveyor belts, preventing premature belt wear. We manufacture and supply high-performance roller accessories, ceramic lag rollers, buffering idlers, and bracket systems that stabilize the belt during transport.

Our heavy-duty belts are trusted by major industrial giants including Jidong Cement Group, Jinmei Group Coal Conveying Line, Taihang Steel, and Puyang Steel Group. These applications confirm our belts maintain low elongation, high abrasion resistance, and excellent adhesion strength across varied operation parameters.
To assure long-term operation on site, every batch of conveyor belts undergoes strict testing in our independent chemical analysis room and physics laboratory. Following our strict policy—no uninspected raw materials enter the plant, and no sub-standard products leave the facility—we inspect every batch of raw rubber, fabric reinforcements, and vulcanized products.

Our manufacturing capacity is backed by a fully automated mixing center with an integrated feeding device, calendering and shaping lines, and high-pressure vulcanization presses. By controlling temperature distributions across the vulcanizing platens, we ensure that Chevron cleats and base belts form as a single piece under high temperature, preventing cleat detachment, which is common in cold-bonded alternative brands.
We work to reduce downtime by offering specialized support packages directly to our industrial buyers in West Java, Banten, and Jabodetabek. Our service structure covers:
