Our registered brand, "Jinao", represents standard-setting quality in heavy-duty conveyor systems.
We are a professional manufacturer in China that integrates product development, research, design, manufacturing, and comprehensive business services for conveyor belts and conveyor machinery accessories. We have passed the international quality management system certification, reinforcing our commitment to reliable manufacturing practices. Our manufacturing hub features multiple advanced production lines for rolling, forming, vulcanization, and state-of-the-art rubber testing (from raw materials to finished products).
A legacy of technical engineering, strict testing, and reliable global logistics.
We feature an independent chemical analysis room and physical laboratory to monitor every phase from raw material procurement to shipping. No unqualified material enters the site, and no sub-standard product leaves.
Professional quality inspectors, sophisticated testing equipment, and advanced destructive and non-destructive testing methods guarantee structural integrity and long service life of our conveyor belts.
Backed by robust technical strength and a responsive after-sales framework, our products are widely exported. We serve key industries including steel, metallurgy, coal mining, cement plants, power generation, port operations, and grains.
An authoritative analysis of high-tension multi-ply rubber belting solutions for bulk handling.
The Supermax 37x2 conveyor belt represents a top-tier specification in high-load bulk handling. Designed to bridge the gap between high-ply fabric belts and heavy-duty steel cord belts, the "37x2" architecture utilizes dual-layer heavy polyester-polyamide (EP) fabric matrices or specifically configured dual steel-cord reinforcement cores. Each tension member is isolated with robust, energy-absorbing skim rubber to optimize adhesion values and resist high-energy impact in bulk feeding stations.
Whether routing run-of-mine (ROM) coal, heavy metallic ores, or hot cement clinker, the structural integrity of the conveyor belt dictates operational uptime. The Supermax 37x2 is constructed using state-of-the-art synthetic polymer compounds that offer high abrasion resistance (often exceeding DIN 22102 Y or W standards), minimal elongation under maximum working tension, and high splice efficiency.
Modern bulk logistics is undergoing a transition driven by larger conveying capacities, steep incline configurations, and sustainable operations. As global operators seek to minimize carbon emissions, the demand for Low Rolling Resistance (LRR) conveyor belts has surged. These specialized rubber compounds reduce energy consumption by minimizing the indentation loss as the belt passes over idlers. For heavy belts like the Supermax 37x2, implementing LRR rubber translates directly into substantial energy cost savings and lower motor driver thermal stress.
Furthermore, smart predictive maintenance has moved from luxury to necessity. Operators are integrating RFID tags, steel cord rip-detection loops, and continuous visual scanners to monitor belt health. Boao’s advanced vulcanization processes ensure that embedded smart sensors maintain structural bonding without introducing delamination points.
For international procurement managers, purchasing a conveyor belt is not just about the initial price tag; it is about mitigating the Total Cost of Ownership (TCO). Unplanned shutdowns in a copper mine or a steel smelting plant can cost upwards of tens of thousands of dollars per hour. Therefore, global enterprises focus on three critical factors:
Based in Boye County's Rubber Industrial Park, Hebei Boao Rubber Technology Co., Ltd. embodies China's modern Factory 4.0 initiatives. By shifting from traditional manual batching to automated, closed-loop carbon black and chemical dosing systems, we eliminate human error from the rubber compound mixing process. Our automated calendering lines achieve precise thickness control down to ±0.1mm, ensuring uniform load distribution across the entire belt width.
This localized supply chain integration—combining domestic synthetic rubber production, high-tensile steel cord sourcing, and specialized weaving plants—ensures that our lead times remain highly competitive, even during periods of global supply chain disruption. Procurement partners benefit from reliable shipping timelines, consistent technical specifications, and factory-direct pricing.
The real-world reliability of "Jinao" products is proven across various operational environments:
Comprehensive service plans to maximize equipment lifecycle and reduce conveyor belt wear.
Our technical team provides planned replacements, structural hot or cold repairs, comprehensive site inspections, preventive maintenance, and emergency rapid-response conveyor services.
We manage everything from the delivery of conveyor belts and raw repair rubber to ensuring optimized safety stock levels. Our services also include systematic belt tension adjustments, edge-wear rebuilding, and professional splice auditing.
Our main goal is to improve the run-time efficiency of your conveyor systems, minimize energy draw, reduce physical carcass wear, and establish a mutually beneficial, high-uptime relationship.

Expert answers to critical procurement and operational engineering questions.
Typically, in high-capacity heavy belting structures, "37" represents either a custom nominal thickness of 37 millimeters for multi-ply belts or a specific high-tensile rating designed to support dual-reinforced steel cord layouts. The "x2" signifies a double reinforcement structure (such as dual breaker layers or dual inner tension members) built to withstand severe drop impact and high-tension strain on long-haul conveyor structures.
We use an advanced computer-controlled mixing system and high-tensile bonding agents. Our laboratories test rubber-to-fabric and rubber-to-steel adhesion values with specialized peeling test machinery. This process guarantees adhesion levels that exceed international standards (e.g., DIN 22102 and ISO 15236), preventing ply separation under heavy loads and tight bending radii.
Yes. We custom-formulate our rubber covers with premium EPDM or chlorobutyl rubbers. This formulation enables the belt to operate in high-temperature environments, carrying hot materials up to 200°C (with peak temperatures reaching 250°C), while maintaining carcass flexibility and tensile strength.
Standard production cycles are 15 to 25 days depending on the order volume and customized design requirements. Thanks to our integrated production capabilities in Boye County, Hebei Province, we maintain reliable supply chains to minimize lead times for our global partners.
