About Metal Shapes and Stock
Metal shapes and stock includes metals and alloys in the form of bar, rod, beam, plate, foil and other standard shapes. There are many different types of metal shapes and stock. Examples include rod, bar, tee, channel, and half-round. The manufacturing process where a metal is pushed and drawn through a die to create a shaped rod, rail, or pipe is called extrusion. The metal shape which is formed by extrusion is called an extruded metal shape. The process usually creates a long length of the final product and may be continuous or semi-continuous in nature. Some metals are hot drawn while others may be cold drawn. Materials that can be extruded are aluminum, zinc, steel, copper and plastics. A bar stock can be classified according to its shape which can be flat, round, square, and hexagonal. Other metal shapes and stock are commonly available.
