Why Choose Jiangsu Cunrui Metal
When sourcing stainless or carbon steel, buyers face three real risks: inconsistent material grades, fragmented suppliers for processing, and delayed or poorly documented shipments. We built our operation to eliminate those risks.
Here's what sets us apart:
Direct Partnerships with Top Steel Mills
We source directly from TISCO, Baosteel, POSCO, and Lianzhong. Every batch ships with MTC and full lot traceability. No middlemen, no substitution, no quality surprises-just consistent, certified raw materials.
In-House Manufacturing & Precision Processing
We're not a trading desk. Our 20,000 sqm facility handles the full chain: raw stock → cutting → slitting → polishing → forming → CNC machining. One invoice, one quality standard, tighter tolerance control. You skip the hassle of coordinating multiple vendors.
Rigorous QC at Every Stage
ISO 9001 certified. Every material undergoes spectrometer grade verification, dimensional checks, and surface inspection before packing. We don't assume compliance-we test for it. If it doesn't match your spec, it doesn't ship.
Customization Without Compromise
Need 316L sheets cut to exact dimensions? Mirror-polished rods? Slitted coils ready for your production line? We adapt to your drawings, not the other way around. Low MOQs for trials, scalable for volume orders.
Global Experience, Local Responsiveness
500+ clients across 30+ countries. 20+ years of export logistics know-how. Engineering and sales teams respond within 24 hours. We handle packaging standards, export documentation, and freight coordination so you can focus on your project.
At Jiangsu Cunrui, our team of metallurgical engineers, production technicians, and export specialists brings over 20 years of hands-on experience in steel manufacturing and international supply. We focus on transparent communication, rapid grade-matching support, and reliable delivery-partnering with you to deliver customized, audit-ready solutions from first inquiry to final shipment.
