Key Standards Comparison Summary
Fire Resistance
All standards require no flame combustion phenomenon during drum friction tests, ensuring immediate self-extinguishing capability in fire scenarios.
Anti-Static Properties
Universal requirement of surface electrical resistance ≤300 MΩ prevents static electricity accumulation and potential ignition in explosive atmospheres.
Temperature Control
Maximum drum surface temperature limit of 325°C ensures belt safety during friction-induced heat generation in emergency situations.
Triple Certification
Our belts meet EN 14973, MT668-2008, and GB 21352-2008 requirements, providing comprehensive safety assurance for global mining operations.

Get instant answers to common questions about our steel cord conveyor belts
Selecting the optimal belt grade depends on several key factors including conveying distance, material characteristics, belt speed, and environmental conditions. Our engineering team analyzes your specific requirements such as tonnage capacity, conveyor inclination, operating temperature range, and material abrasiveness. For most mining applications, ST2000-ST3000 grades provide ideal strength, while lighter-duty operations like cement plants perform well with ST1250-ST1600 grades. We provide detailed technical consultations to match your exact operational parameters with the most cost-effective belt specification.
Our advanced production facilities can manufacture steel cord belts up to 3,000 meters in continuous length, eliminating the need for multiple splices on long conveyor systems. For exceptionally long installations exceeding 3km, we design optimized splice locations to minimize joint points while maintaining system integrity. Transportation logistics vary by destination, but we utilize specialized shipping methods including custom steel core spools and protective wrapping to ensure safe delivery worldwide.
Absolutely. Every belt shipment includes comprehensive documentation detailing all quality control test results performed during manufacturing. Standard test certificates cover tensile strength verification, adhesion force measurements, elongation characteristics, cover rubber thickness, steel cord diameter and spacing, and vulcanization quality indicators. Additional certifications available include ISO 9001 quality management compliance, international safety standard conformity (MSHA, CE), material composition analysis, and third-party laboratory verification reports when requested.
Standard production lead time ranges from 25-35 days depending on belt specifications, order quantity, and current production schedule. Custom specifications or special rubber compounds may require additional 7-10 days for formulation and testing. Rush orders can often be accommodated with expedited production scheduling when urgent replacement needs arise. Delivery timeline varies by destination, typically 15-30 days for ocean freight to major ports worldwide, or 7-15 days via air freight for critical urgent shipments.
Yes, we offer comprehensive OEM and private label manufacturing services for distributors and large-scale industrial users. Our capabilities include custom logo embossing on belt surfaces, branded packaging with your company information, and tailored specifications to match your unique operational requirements. We can modify cover rubber compounds for specific resistance properties, adjust steel cord configurations for particular strength requirements, and customize dimensions beyond standard catalog offerings. Minimum order quantities for OEM production typically start at 1,000 meters to ensure cost-effectiveness.
