| Steel Cord Strength Range | Heavy-duty steel cord conveyor belts for mining, ports, power plants, and bulk-material handling | Common belt strength classes include ST1000 to ST7500; higher grades are available for long-distance and high-capacity systems | Request tensile-strength test reports and confirm compliance with the specified belt-strength class |
| Belt Width | Standard and customized widths for underground, surface, overland, and ship-loading conveyors | Typical widths range from approximately 800 mm to 2400 mm; wider belts may be produced for specific projects | Check usable belt width, edge construction, dimensional tolerance, and roll-length capability |
| Cover Rubber Options | Cover compounds designed for abrasion, heat, oil, flame, cold, and impact resistance | Common cover thicknesses are about 4–8 mm on the top side and 2–6 mm on the bottom side, depending on application | Verify cover grade, abrasion-loss results, thickness tolerance, and application temperature range |
| Steel Cord Construction | Longitudinal high-tensile steel cords embedded in a rubber compound with transverse reinforcement where required | Cord diameter, pitch, lay length, zinc coating, and cord adhesion are selected according to belt strength and splice design | Request cord-construction drawings, cord pull-out results, and dynamic fatigue-test data |
| Applicable Standards | Products may be manufactured to Chinese, international, or customer-specific technical specifications | Frequently referenced standards include ISO 15236, DIN 22131, and GB/T 9770 | Confirm the exact standard edition, test method, acceptance criteria, and certificate validity |
| Splice Compatibility | Hot-vulcanized finger and stepped splices supported for high-tension steel cord systems | Splice design depends on belt strength, cord diameter, pitch, pulley diameter, and conveyor operating conditions | Obtain splice drawings, joining procedures, recommended materials, and field-service requirements |
| Resistance Properties | Specialized compounds available for abrasive ores, hot materials, oily materials, and underground applications | Heat-resistant grades are commonly specified for material temperatures around 100–180°C, subject to compound and exposure time | Match the belt grade to actual material temperature, oil content, abrasion level, and fire-safety requirements |
| Quality-Control Testing | Routine inspection of rubber compounds, steel cord alignment, adhesion, tensile strength, elongation, and belt dimensions | Typical documentation includes batch records, physical-property reports, dimensional inspection, and finished-belt test results | Ask for a certificate of analysis, inspection plan, traceability records, and independent inspection options |
| Customization Capability | Custom belt width, strength class, cover compound, edge type, rubber grade, roll length, and packaging | Design inputs normally include conveyor length, belt speed, capacity, incline, pulley diameter, material density, and ambient conditions | Provide a complete conveyor data sheet before requesting a technical and commercial quotation |
| Export and Project Support | Export-oriented manufacturers commonly provide seaworthy packing, technical documentation, installation guidance, and remote support | Important documents may include commercial invoices, packing lists, certificates of origin, inspection reports, and splice manuals | Evaluate delivery schedule, warranty terms, spare materials, installation support, and after-sales response time |
