===Steel===
From Birmingham's early days onward, the steel industry has always played a crucial role in the local economy. Though the steel industry no longer has the same prominence it once held in Birmingham, steel production and processing continue to play a key role in the economy. Steel products manufacturers [[American Cast Iron Pipe Company]] (ACIPCO) and [[McWane]] are based in the city. Several of the nation's largest steelmakers, including [[Commercial Metals Company|CMC Steel]], [[U.S. Steel]], and [[Nucor]], also have a major presence in Birmingham. In recent years, local steel companies have announced about $100&nbsp;million worth of investment in expansions and new plants in and around the city. [[Vulcan Materials Company]], a major provider of crushed stone, sand, and gravel used in construction, is based in Birmingham.
