Sheet metal is metal formed by an industrial process into thin, flat pieces. Sheet metal is one of the fundamental forms used in metalworking and it can be cut and bent into a variety of shapes. Countless everyday objects are fabricated from sheet metal. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate steel or "structural steel."
Manufacturing is the production of products for use or sale using labour and machines, tools, chemical and biological processing, or formulation, and is the essence of secondary industry. The term may refer to a range of human activity, from handicraft to high tech, but is most commonly applied to industrial design, in which raw materials from primary industry are transformed into finished goods on a large scale. Such finished goods may be sold to other manufacturers for the production of other more complex products
Metal fabrication is the creation of metal parts, machinery, or components through forming, cutting, and other like processes. Common fabrication techniques include welding, lathing, broaching, grinding, milling and honing, though many metal fabrication shops offer a variety of specialties that may be well-suited to your specific needs. A vital process for virtually all manufacturers, metal fabrication ranges from industries such as automotive and electrical to food and beverage.
