Quality Control Excellence at Jiangsu China Steel Union Industrial Co., Ltd

At Jiangsu China Steel Union Industrial Co., Ltd, we specialize in premium stainless steel, aluminum, and copper products (plates, pipes, coils, bars) trusted by global clients. Our 3-stage quality control system ensures every shipment meets ASTM, EN, JIS, and GB standards:

1. Material Integrity: Raw materials undergo XRF/X-ray testing to verify composition (e.g., 304/316L stainless steel, 6061 aluminum). Certified mills supply traceable alloys with EN 10204 3.1 inspection certificates.

2. Precision Manufacturing: CNC-controlled rolling mills maintain ±0.05mm thickness tolerance. Hydrostatic/pressure tests validate pipe durability (up to 1000 PSI).

3. Final Verification: Third-party labs (SGS/BV) conduct salt spray testing (2000+ hours), hardness checks (HRB/HV), and surface finish analysis (Ra ≤0.8μm).

All products are RoHS/REACH compliant and packed with anti-corrosion VCI films for safe transit. Our ISO 9001-certified workflow guarantees:

• 100% dimensional accuracy for seamless integration

• Full traceability via heat-number tracking

• 30-day replacement warranty for quality disputes

With 12+ years of exporting expertise to 50+ countries, we combine German-engineered testing equipment and transparent documentation (mill test reports, material certificates) to build trust.
