Ryerson has a heart of steel. A distributor and processor of metals, the company offers its customers more than 70,000 products made of steel (carbon, stainless, and alloy) and aluminum, brass, copper, and nickel alloys. It buys bulk metal products (in sheets, bars, and other forms) from metal producers and processes them to meet the specifications of its customers -- machine shops, fabricators, and machinery makers. The company also offers pipes, valves, and fittings; metal roofing, flooring, and grating products; and fabrication services. Most of Ryerson's almost 100 facilities are in the US. Ryerson went public in late 2014.
