Frequently Asked Questions
Do you manufacture customized rolls according to our specific drawings and tolerances?
Absolutely. We specialize in precision machining for rolls ranging from Ø270mm to Ø1000mm. Equipped with comprehensive CNC lathes and grinders, we strictly adhere to your tolerances, whether it requires complex pass profiles or specific surface finishes, ensuring a seamless, plug-and-play fit in your mill.
Roll breakage is a major concern. How do you prevent hidden internal defects?
We eliminate guesswork through verifiable data. Every roll undergoes precise chemical analysis pre-furnace, and 100% A-scan digital ultrasonic testing (UT) post-production. This rigorous process effectively identifies and screens out internal flaws, mitigating the risk of in-mill failures.
What is your standard lead time for small to medium-sized rolls?
Standard lead times typically range from 50 to 120 days, depending on material complexity and machining requirements. Supported by our 15,000-ton annual capacity, we carefully plan production schedules to ensure reliable, on-time delivery for your routine maintenance.
What is your Minimum Order Quantity (MOQ)? Do you accept small trial orders?
We understand that switching suppliers requires rigorous testing. We fully support trial orders and do not impose strict MOQs for first-time cooperation. You can start with 2 pieces to verify our roll performance in your actual production environment
How do you offer competitive pricing while maintaining high-end wear resistance?
We optimize your comprehensive procurement cost through lean operations. By deeply integrating the entire internal workflow—from raw material melting to final CNC machining—we maximize efficiency and eliminate unnecessary operational waste, passing the cost benefits directly to you.
