Specially customized for heavy-duty material transport and steep-angle incline bulk handling in South Asian industrial clusters.
Sri Lanka's strategic location in the Indian Ocean has positioned it as a vital maritime and logistical hub. With massive port expansions, including the Colombo Port expansion (East Container Terminal) and the Hambantota Port industrial zone, the demand for bulk handling systems has reached an all-time high. Major local industries such as cement manufacturing (clinker and slag handling at plants in Galle and Trincomalee), mineral sand mining, and aggregate processing require high-capacity material handling systems that can operate in challenging tropical environments.
High-inclination corrugated sidewall conveyor belts are crucial in these installations. By permitting material lifting at angles from 30° up to 90°, they dramatically reduce the ground footprint needed for conveyor loops. For Sri Lankan manufacturing facilities facing land restrictions in high-density industrial zones near Colombo, implementing our vertical pocket belts has become the industry standard for optimization.
Sri Lanka's tropical climate—characterized by high humidity, intense UV exposure, and coastal salinity—accelerates the wear and oxidation of standard rubber compounds. Sourcing inferior grade conveyor belts results in rapid cracking, sidewall separation, and costly unscheduled downtime for processing facilities. Heavy rains can wash away materials on traditional flat belts, necessitating the deployment of high-rigidity transverse cleated belts with side walls.
Hebei Boao Rubber Technology Co., Ltd. addresses this gap by engineering customized rubber conveyor belts with enhanced anti-aging, UV-resistant, and anti-static properties under our brand "Jinao". Our belts are specifically formulated to withstand the humid conditions of Galle, the chemical exposure of Trincomalee’s fertilizer terminals, and the mechanical abrasion of Colombo's aggregate crushing plants.
Understanding the engineering details that prevent material spillage and prolong operational lifetime.
Standard conveyor belts sag under high tension when loaded laterally. Our XE-reinforced base belts integrate high-tensile monofilament cross-rigid plies that provide vertical stability, preventing bowing on return idlers while maintaining longitudinal flexibility for smooth pulley wrap.
The sidewalls are vulcanized to the base belt using high-frequency cold bonding or hot vulcanization. The corrugated design acts as a flexible bellows, absorbing mechanical tension during curve transitions without cracking or delamination.
Cleats form pockets that lift material securely up to 90°. We offer T-cleats for low inclines, C-cleats for abrasive materials, and TC-cleats (heavy-duty segmented pockets) designed for high capacity, highly abrasive mineral sands and coal transport.
| Profile Type | Maximum Incline Angle | Suitable Materials | Typical Sri Lankan Applications |
|---|---|---|---|
| T-Cleat | Up to 40° | Fine powders, grain, dry tea leaves | Agro-processing, light chemical packaging |
| C-Cleat | 40° to 60° | Wet sand, crushed limestone, clinker | Tokyo Cement plants, river sand dredging |
| TC-Cleat | 60° to 90° | Heavy ores, coal, large aggregate, slag | Hambantota coal terminals, quarry plants |
Founded in 2004, Hebei Boao Rubber Technology Co., Ltd. is located in the Rubber Industrial Park of Boye County, Baoding, Hebei Province. Over the past 22 years, our facility has grown to span more than 30 acres. We are a professional manufacturer in China that integrates product development, research, design, manufacturing, and technical support for industrial conveyor belts and supporting machinery accessories.
Under our premium registered brand "Jinao", we have passed the international quality management system certification on our first attempt. Equipped with state-of-the-art production lines for calenders, forming machines, and high-pressure vulcanizers, we control the entire quality pipeline from raw rubber importing to final product shipping.
Adhering to strict international standards to ensure reliability under extreme mechanical stress.
We host an independent physical testing laboratory and chemical analysis room. Every batch of synthetic and natural rubber compound is analyzed before formulation. Our quality inspectors verify key properties: tear strength, elongation at break, ozone resistance, and adhesion layers. Products that do not meet our standards are rejected.
Our quality assurance testing includes: dynamic fatigue testing, steel cord pull-out testing, peeling tests, and abrasion testing. This ensures that every belt shipped to Sri Lanka's ports or mining zones operates reliably, minimizing belt joint failures and surface wear.
Our Jinao brand conveyor belts are engineered to comply with ISO9001, ISO14001, ISO18001, CE, and European DIN/national standard protocols. If your project in Colombo or Trincomalee requires certified flame retardancy, chemical resistance, or food-grade safety standards, we can provide third-party verified certificates upon request.

Providing specialized conveyor belt designs for different key industrial applications in Sri Lanka.
In cement production centers like Galle and Trincomalee, transferring hot clinker and abrasive limestone demands belts that can withstand extreme temperatures. Our high-temperature resistant corrugated sidewall belts handle continuous temperatures up to 200°C without cracking, ensuring uninterrupted transport from the kiln to the storage silo.
Colombo and Hambantota Ports require high-throughput conveying systems to load and unload bulk carriers efficiently. Our high-inclination sidewall belts enable vertical lift within tight port facilities, transferring grain, coal, and sand directly from vessels to storage warehouses with zero product spillage.
Sri Lanka's graphite mines require high-performance, tear-resistant belts to transport heavy minerals from deep shafts to processing stations. Our steel wire rope core sidewall belts provide high longitudinal tensile strength, enabling vertical lifts over long spans with minimal stretch.

Our heavy-duty rubber belts are trusted in critical infrastructure projects by global mining and infrastructure enterprises.
We do not just manufacture belts; we partner with your engineering teams to maximize equipment lifespan. For major operations in Sri Lanka, we provide end-to-end support packages:
Buying from multiple suppliers often introduces material compatibility issues. Jinao provides integrated solutions, supplying not only main sidewall belts but also steel buffer rollers, impact beds, return idlers, and drive pulleys. This ensures uniform wear characteristics and extends the operational life of the entire conveyor line.
