Established in 2004, Hebei Boao Rubber Technology Co., Ltd. is positioned in the heart of the Boye County Rubber Industrial Park, Baoding, Hebei Province. Over the span of more than two decades, we have evolved into a leading enterprise focusing on the R&D, design, manufacturing, and customized integration of premium quality conveyor belts and supporting conveying machinery accessories. Under our renowned brand "Jinao", we represent excellence and durability on a global scale.
Our expansive production campus covers more than 30 acres, hosting multiple advanced, automated lines for rubber rolling, belt shaping, continuous vulcanization, and material testing. We boast a fully accredited international quality management system certification, guaranteeing that every conveyor belt leaving our facility matches the high standards expected by our global B2B procurement partners.
Understanding the physics, geometry, and design principles that enable high-angle slip-free conveying.
Traditional flat belts struggle at angles exceeding 18 degrees due to gravity-driven backslide. The Concave Herringbone (often referred to as Chevron or V-profile) uses specialized recessed or raised cleat geometries to create micro-pocket dams. These dams trap material and increase the internal friction angle of the load, permitting vertical transit up to 40 degrees.
A major failure point of cheap profiled belts is material accumulation within the grooves. Our proprietary concave designs feature smooth transition radii at the root of each Herringbone pocket. As the belt passes over return idlers and wrap pulleys, the elastic deflection of the rubber naturally flexes the grooves open, discharging sticky fines and dust.
The concave profile of the chevron pattern acts as an alignment guide for bulk materials. By guiding the bulk mass toward the centerline of the belt, dynamic load displacement is reduced. This reduces tracking errors, prevents edge wear, and protects the structural health of the conveyor support frame.

| Belt Width (mm) | Pattern Type | Cleat Height (mm) | Carcass Material Options | Max Conveying Angle | Applicable Standards |
|---|---|---|---|---|---|
| 300 - 650 | Open V / Closed V / Multi-V | 5, 10, 15 | EP (Polyester), NN (Nylon), Steel Cord | Up to 25° | DIN 22102, AS 1332, GB/T 7984 |
| 700 - 1000 | High-Pattern Herringbone | 15, 20, 25 | EP 200 - EP 400 Multi-ply | Up to 32° | ISO 14890, BS 490 |
| 1050 - 1600 | Concave Reinforced Chevron | 25, 32 | High Tension EP / NN / Steel Cord | Up to 40° | DIN 22131 (Steel Cord), JIS K6322 |
Modern B2B buyers look beyond simple price-per-meter metrics. High-capacity operations require components that minimize downtime and lower the Total Cost of Ownership (TCO). Our Jinao brand focuses on satisfying these specific demands:
Carcass Integrity: Our polyester (EP) and nylon (NN) fabrics are sourced from top industrial yarn producers. They undergo precise tensioning during the calendering process to ensure low elongation under load, avoiding the need for frequent take-up adjustments.
Compound Formulation: We offer custom rubber compounds suited for specific environments: high temperature, extreme cold, acid/alkali exposure, and flame-retardant scenarios. Our laboratories test each batch for abrasion resistance (measured in mm³ loss according to DIN 53516) to ensure extended service life.
We operate an independent quality control department that inspects production from compounding to final curing. Tests include carcass adhesion, cover tensile strength, elongation at break, and pattern height consistency. No batch is approved for dispatch until it matches the required specifications.
With an annual output of millions of square meters, we maintain safety stocks of standard belt widths to support critical project schedules. Our logistics network handles shipping from Tianjin Port, ensuring timely delivery to international markets.
How Hebei Boao Rubber Technology supports your operational life cycle from design to installation.
We provide comprehensive lifecycle support, including planned belt replacements, surface repairs, inspections, and emergency technical services. We aim to keep your systems running smoothly with minimal unplanned downtime.
Our service packages cover the supply of premium conveyor belts and rubber materials, safety stock management, vulcanized splicing, cover wear repairs, alignment tracking, and regular system audits.
We focus on improving conveyor operating efficiency, reducing belt wear, extending pulley life, and lowering energy consumption. We build relationships with our clients based on mutual success and shared value.
Our conveyor belts are field-tested in demanding material handling applications across the globe.
Supplied high-inclination patterned belts for stable, continuous sand and aggregate transport under high-volume conditions.
Delivered heat-resistant and chevron belts to transport hot clinker at steep angles, reducing material rollback.
Installed high-tensile steel cord and flame-retardant belts for heavy-duty underground coal conveyance.
Provided acid and alkali-resistant belts to support processing lines for nickel and stainless steel production.
Delivered durable conveyor systems to transport abrasive sinter and iron ore under continuous high-temperature loads.
Supplied high-durability patterned belts designed for raw limestone handling in wet, slippery conditions.
Our facility houses high-precision equipment to monitor quality from raw polymer blending to final curing tests.
The next generation of high-inclination material transport technology.
Energy consumption is a major operating cost for long-distance conveyors. Our R&D team is developing Low Rolling Resistance (LRR) backing compounds that reduce indentation losses as the belt passes over idlers, potentially saving up to 15% in drive power requirements.
We are piloting smart monitoring solutions that integrate RFID tags and copper sensor loops directly into the conveyor belt carcass. These sensors communicate with real-time scanners to track cover wear, detect longitudinal tears, and alert operators before catastrophic belt failures occur.
Aligned with global sustainability initiatives, our compound development includes devulcanized recycled rubber and bio-sourced processing oils. These materials maintain the tensile and abrasion properties of Jinao belts while lowering their overall carbon footprint.
