About Gerdau Ameristeel

Gerdau Ameristeel puts its stamp on the steel business in the US. The company is one of the largest minimill steelmakers in North America, with a capacity to produce about 10 million tons of finished steel annually.  Through about 20 mills, Gerdau Ameristeel sells to the eastern two-thirds of North America. The company also operates scrap recycling – more... operations, specialty processing centers, and rebar fabricating and coating plants. Its minimills produce beams, flat-rolled steel, merchant bar, rebar, and wire rod primarily used in the automotive, appliance, construction, machinery, and equipment industries. The company is owned by Brazilian steelmaker Gerdau.


The company has an annual capacity of 9.9 million tons of crude steel and 9.2 million tons of rolled products. Gerdau Ameristeel subsidiaries are Gerdau USA Inc., Gerdau Ameristeel US Inc., GNA Partners, Pacific Coast Steel Inc., Gerdau Ameristeel Perth Amboy Inc., Sheffield Steel Corporation, Gerdau Ameristeel Sayreville Inc., TAMCO Steel and, Chaparral Steel Company. Gerdau Ameristeel also has a 50% interest in the jointly controlled entity Gallatin in Kentucky.

The company produces special sections such as grader blades, smelter bars, light rails, super light I-beams, elevator guide rails and other products that are made on demand for its clients, which are mainly manufacturers.

Gerdau Ameristeel also supplies flat steel to its customers through its  Gallatin unit.

Recycled scrap metal provides more than 90% of the steel for its minimills, making the company the continent's second-largest scrap recycler. Its own scrap operations provide much of the raw material for the minimills. And once the company's minimills produce the steel, the steel product can be sent to its many downstream operations, which include rebar fabrication plants, railroad spike makers, wire and nail operations, and cold drawn plants.


Gerdau Ameristeel reported in 2011 that it had manufactured 17,000 tons of sheet piling for the Panama Canal expansion, a major $5.25 billion project that will double the capacity of the canal, allowing more ships (and larger ships) to traverse it.

That year Gerdau Ameristeel opened a new rebar fabrication facility in Navasota, Texas, to serve the Houston construction market. The facility will have an eventual capacity of 40,000 tons.

Earlier in 2010 Gerdau Ameristeel acquired TAMCO, a California-based mini-mill, for $165 million from a joint venture that included Ameron International, Mitsui & Co.,  and Tokyo Steel. TAMCO has one of the largest rebar mills in the Western US, distributing primarily in California, Arizona, and Nevada.


Parent company Gerdau SA, which already owned most of Gerdau Ameristeel, moved to buy all outstanding shares in 2010, taking the company private and making it a wholly-owned subsidiary.  – less
