The Sidegua Masagua steel plant is Central America's largest steel producer[2][3], with an annual production capacity of 500,000 tonnes of crude steel.[1] Construction of the plant began in 1991[4][5], and commercial operations began three years later.[2][5] The plant is a project of Aceros de Guatemala SA, a private company founded in 1962.[5][6] Brazilian steelmaker Gerdau acquired a 30% stake in the company in 2008.[3][7]

The Masagua plant produces steel billets, which are transformed by Sidegua's six Central American facilities into a variety of finished steel products, including rebar, wire rod, profiles, herringbone wire, galvanized wire, tie wire, cyclone mesh and electro-welded mesh for the civil construction sector.[2] The plant operates a Tamini electric arc furnace (EAF).[1][8]
