The Mills Behind Every Coil GR Trading Sources
GR Trading sources exclusively from a select group of world-class Chinese steel mills — facilities with the scale, technology, and quality systems to meet the exacting demands of U.S. metal can and packaging manufacturers. Every coil we bring to market originates from a vetted production partner with a proven record of consistency, capacity, and compliance. Below are the primary mills powering GR Trading's supply chain.
Shougang Group
A Global Steel Powerhouse With a Century of Industrial Leadership
Founded in 1919 and ranked among the Fortune Global 500 thirteen times, Shougang Group stands as one of the most consequential steel producers in the world. With nearly 500 subsidiaries and over RMB 500 billion in assets, Shougang has grown alongside China's steel industry into a genuinely global enterprise. Its recognition as "excellent" under China's elite Double Hundred Enterprises program reflects both its operational strength and its role as a model for state-owned industrial reform. Shougang has remained ahead of the curve throughout its evolution — relocating production to advanced coastal facilities like the Caofeidian Steel Dream Factory and building a modern, high-capacity system purpose-built for high-end steel products.
Advanced Technology. Sustainability. Product Quality.
Shougang leads the Chinese steel industry in ultra-low emission production and supplies some of the most demanding manufacturers in the world, including BMW, Siemens, and BYD. Its product range spans top-tier automotive, electrical, and specialty steels used in high-speed rail, aerospace, and energy infrastructure. Beyond manufacturing, Shougang has redefined what an industrial company can be — transforming former production sites into innovation hubs and Olympic facilities, establishing itself not just as a manufacturer, but as a forward-thinking, environmentally responsible, and globally competitive enterprise.
TCC Steel
Precision Manufacturing. Decades of Reliability. 60+ Countries Served.
TCC Steel is a standout mill defined by its combination of precise manufacturing capability and an unwavering commitment to long-term reliability. The company maintains strict consistency across its operations, ensuring every product meets demanding quality standards before it ships. With advanced production infrastructure and decades of operational experience, TCC supports industries where performance tolerances leave no room for error — packaging, electronics, and energy materials chief among them. Supplying customers across more than 60 countries, TCC has earned a reputation as a dependable, high-output partner in the global steel market.
R&D-Driven Innovation Since 1988
What distinguishes TCC Steel beyond its manufacturing scale is its sustained investment in research and development. Since establishing its R&D center in 1988, TCC has spent more than three decades advancing its technologies and expanding its product portfolio — backed by hundreds of engineers and technical staff. That investment has produced specialized materials including coated and plated steels engineered for the most demanding applications: electric vehicle battery casings, advanced packaging solutions, and high-performance industrial products. This commitment to innovation, paired with a strong emphasis on sustainability and production efficiency, positions TCC Steel as a modern, forward-thinking mill built for the long term.
Why GR Trading Sources From These Mills
Both Shougang Group and TCC Steel share the characteristics GR Trading requires in every mill relationship: verified quality systems, proven capacity at scale, documented track records in demanding end markets, and the technical depth to produce specialty coated and plated steels to specification. GR Trading's role is to bridge these world-class production capabilities with the procurement teams, quality managers, and supply chain directors at U.S. manufacturers who need those materials — on time, to spec, and with full traceability from mill to delivery.
