Crafting Metal Coils: The Production and Growth Story of Our Factory

We are Jiangsu Zhongtong Weiye Special Steel Co., Ltd., a metal coil and sheet supplier based in Xishan District, Wuxi—China’s special steel hub. This is not a generic factory story; it is a rundown of what we actually stock, process, and ship every week to customers in 30+ countries.

What We Stock and Slit

Our warehouse carries four product families in coil and sheet form:

  • Electrical steel: CRGO (grain-oriented) and CRNGO (non-oriented) silicon steel in 0.10–0.50 mm. Grades include 27Q110/120, 30Q120, M4–M6, and M19–M43.
  • Copper and brass: C11000, C12200, C26800, C28000 plate and tube in mill finish or annealed.
  • Nickel alloys: Hastelloy, Inconel, Monel, and pure nickel plate, sheet, and bar.
  • Wear and mold steel: NM360/NM400 wear plate, H13/D2 mold steel in cut-to-size blanks.

Furthermore, we slit coil to your exact width. Standard slitting tolerance is ±0.10 mm. For transformer core customers, we can supply pre-slit strip ready for core cutting.

Our Processing Capabilities

We do not just resell mill stock. We add value before shipment:

  • Slitting: coil to narrow strip, width from 20 mm to 1250 mm.
  • Cut-to-length: coil to sheet, length tolerance ±1 mm.
  • Edging: slit edge, mill edge, or deburred edge as specified.
  • Packing: export seaworthy packing with VCI paper and wooden crates.
  • Documentation: mill test certificate with every shipment—chemistry, mechanical properties, dimensions.

How We Work With International Buyers

We export to Southeast Asia, the Middle East, Europe, and North America. Consequently, we understand export documentation:

  • Proforma invoice with HS code and specification.
  • Packing list with gross/net weight and volume.
  • Mill test certificate in English.
  • FOB Shanghai or Ningbo terms as standard.

Typical lead time: stock items ship within 7 days; custom slit or cut-to-size within 15 days; mill-direct orders 30–45 days.

Sustainability and Quality

We do not make vague claims about green manufacturing. In practice: we recycle all slit edge trim back to the mill; we use VCI packaging that reduces corrosion during ocean transit; and we maintain batch traceability from mill heat number to shipment container. Every coil we ship carries a unique heat number that traces back to the original mill melt.
