Explore our leading industrial conveyor belt solutions optimized for extreme conditions, wear resistance, and steep inclines.
In heavy-duty bulk handling, transporting materials up steep inclines presents significant challenges. Raw materials like dry powders, wet gravel, coal, and iron ore tend to slide backward once inclination exceeds the natural coefficient of friction. This is where Strip Patterned Conveyor Belts become critical components of advanced bulk transport systems.
Unlike flat belts, strip patterned and chevron conveyor belts feature integrated profiles (such as Herringbone, V-shapes, U-patterns, and Multi-rib designs) that are molded directly into the top cover rubber during the vulcanization process. This monolithic design creates a mechanical mechanical lock against the cargo, preventing back-slip at angles ranging from 15° up to 45°. This geometry optimizes space utilization in plants, allowing steep transport routes over shorter horizontal spans.
A trusted global leader delivering performance-engineered conveyor belts for heavy industrial bulk handling.
Located in the Rubber Industrial Park of Boye County, Baoding, Hebei Province, Hebei Boao Rubber Technology Co., Ltd. was founded in 2004 and covers an area of over 30 acres. Over the past two decades, our proprietary brand "Jinao" has become a standard of quality, integrating product development, rigorous laboratory research, CAD-driven system designs, modern vulcanizing lines, and robust logistical services.
We operate highly automated production lines for rolling, forming, and continuous vulcanization, supported by an advanced in-house rubber testing laboratory. Our processes ensure every belt is built for longevity and durability under extreme conditions.
With strong technical strength and a comprehensive after-sales system, our products are widely exported across the globe, serving key sectors including steel mills, metallurgy, coal mines, cement plants, power generation stations, fertilizer facilities, grain ports, and maritime cargo hubs.
How Strip Patterned Conveyor Belts solve specific high-volume conveying challenges in different regions.
1. South American Copper and Iron Ore Operations (High-Volume Mining): Large mining complexes in Chile, Peru, and Brazil require steep inclines to lift crushed ores out of open pits. Strip patterned belts reinforced with nylon (NN) or steel cord cores provide high tensile strength and impact resistance, allowing vertical lift while reducing dust emissions and back-slip.
2. North American & European Grain Processing and Storage: In port hubs and massive silos, grain must be moved rapidly. Standard belts slip at 16 degrees, but our food-grade strip patterned PVC and PU belts allow grain transport at up to 35-degree inclines. This design reduces space requirements and improves facility throughput.
3. Aggregates and Construction Materials in Southeast Asia & Middle East: Infrastructure development requires the transport of abrasive sands, limestone, and gravel. Strip patterned profiles help manage wet materials, channeling water away through designed grooves while conveying aggregate materials up steep mixing plant routes.
4. High-Temperature Steel and Coke Operations: Moving hot materials like coke or sintered iron ore in steel mills requires heat-resistant conveyor belts. Our EP/NN layered belts, customized with strip patterns, handle materials at temperatures up to 200°C without profile distortion.

How Hebei Boao maintains reliability, cost stability, and fast global delivery through regional integration.
Hebei Boao operates in Boye County, Hebei Province, the heart of China’s rubber manufacturing cluster. This location provides access to raw materials, synthetic polymers, high-tenacity polyester/nylon fabric weaves, and advanced equipment machinery. This industrial concentration allows us to shorten research-to-production cycles and manage production costs effectively.
Our facility features an independent chemical analysis room and physics laboratory. We conduct raw material inspections and run dynamic testing on finished belts to ensure strict quality control. This internal validation process confirms that every batch meets global standards before shipment.
With our proximity to Tianjin Port, one of Northern China’s largest maritime hubs, we offer reliable shipping timelines. Our logistics networks support quick delivery to North America, South America, Europe, Australia, and Africa, minimizing project lead times.
The next generation of industrial conveyor belts: Smart tracking, low-emission formulations, and advanced compounding.
Integrating RFID and copper indicator loops into rubber plies to monitor real-time cover wear, prevent tearing, and detect alignment issues before failure.
Developing low rolling resistance (LRR) rubber compounds for bottom covers, reducing conveyor drive motor energy consumption by up to 15%.
Incorporating sustainable, non-petroleum based polymers into light-duty PVC/PU strip belts to help global customers meet carbon neutrality goals.
Formulating specialized rubber matrices that retain elasticity in extreme cold (-50°C) and resist surface breakdown in high heat (250°C).
Strict QA protocols verifying physical and chemical properties from raw polymer to vulcanized belt.
Verifies polymer cross-linking density, carbon black dispersion, and antioxidant quality for long life cycles.
Tests tensile strength, elongation at break, DIN abrasion volume loss (mm³), and ply-to-ply adhesion levels.
Monitors temperature and pressure controls to ensure consistent curing and profile integrity.
In order to gain consumers' full trust in the reliability of "Boao" products, we are actively committed to enterprise product quality certification. We have established an ISO 9001-certified Quality Management System to ensure operational consistency across all production stages.
Our belts are designed and manufactured to comply with key international standards, including DIN 22102 (Germany), BS 490 (UK), AS 1332 (Australia), RMA (USA), and JIS K6322 (Japan). This compliance makes our conveyor belts suitable for integration into existing systems worldwide.

Answers to common technical questions regarding selection, maintenance, and operation of strip patterned conveyor belts.
While standard flat conveyor belts generally operate at angles up to 15° to 18° (depending on the material), strip patterned and chevron belts can handle inclinations from 15° up to 45°. The exact allowable angle depends on material characteristics: dry free-flowing grains can be carried up to 30°, whereas damp materials like wet coal or sand can climb up to 45° using appropriate cleat heights.
Unlike secondary vulcanized or glued-on cleats that can peel under high load stress, Jinao brand patterned belts feature integrated, monolithically vulcanized profiles. The top rubber cover and the profile shape are cured together in high-pressure molds, creating a single unit. This design prevents detachment even when conveying heavy, sharp ores.
EP (Polyester warp / Nylon weft) fabric offers low stretch, high dimensional stability, and resistance to chemical moisture, making it suitable for medium-to-long distance conveyors. NN (Nylon warp & weft) provides higher elasticity, impact resistance, and flexibility, making it the preferred carcass for high-shock aggregate handling and heavy-impact drop zones.
Standard primary polyurethane scraper blades are not suitable for patterned belts as they catch on the raised cleats. We recommend rotary motorized brush cleaners, secondary return-side belt beaters, or water spray wash systems. These methods remove sticky fines and carryback without damaging the vulcanized profiles.
To provide an accurate technical quote, we require: 1. Conveyed material properties (bulk density, particle sizing, moisture content). 2. Conveyor layout details (horizontal distance, lift height, angle of incline). 3. Belt specifications (belt width, required tensile rating like EP400/3, cover thickness, and desired pattern style).
