Sheet metal operations have been in existence since 8000 B.C. Sheet metal is simply metal formed into thin and flat pieces. It is one of the fundamental forms used in metalworking, and can be cut and bent into a variety of different shapes. Due to its long history, sheet metalworking is, unfortunately, often seen as archaic and uninteresting. That metal sheets can be transformed with the aid of robust machines intonfancy consumer products with tight tolerances is inconceivable to many. Yet, sheet metal operations are used for producing both structural components and durable consumer goods. Nowadays, sheet metal parts are widely present in different daily life products. During the past decades, scientific research in the field of sheet metal operations has been booming and international conferences on different sheet metal topics attract numerous attendants. Both industry and the academic community recognize the importance of continuing improvement in sheet metal operations. Application Sheet and plate metal parts for consumer and industrial products such as: Automobiles and trucks, Airplanes, Railway cars and locomotives, Farm and construction equipment, Small and large appliances, Office furniture & Computers and office equipment. Advantages High strength, Good dimensional accuracy, Good surface finish, Relatively low cost, For large quantities, economical mass production operations are available. Uses The most common end uses for sheet metal have been electronic enclosures, such as personal computer housings or casings; roofing and roof drainage equipment; air conditioning ducts and stovepipes; sheet metal flooring and siding; awnings, canopies, cornices, and soffits; culverts, flumes, and irrigation pipes; and other or unspecified uses. These categories cover a myriad of products used by every industry, including aircraft manufacture (air cowls); building construction (siding, stove hoods, and gutters); heating, ventilation, and air conditioning (HVAC) applications (ducts, furnace flues); mineral processing (coal chutes); highway construction (guardrails); agriculture (irrigation pipes); business machines (computer casings); shipbuilding (ship ventilators); postal delivery (mailboxes); and food preparation (vats and bins). Market Survey According to industry statistics from Dun and Bradstreet, there were an estimated 5,917 establishments engaged in manufacturing sheet metal work for buildings (not including fabrication work done by construction contractors at the place of construction) in 2010 with revenues of more than $10.7 billion employing 115,838 workers. States with the highest concentration of establishments in this industry were California (15 percent), Texas (8 percent), Florida (5 percent), Pennsylvania (4 percent), and Ohio (4 percent). California accounted for the most sales, with $1.5 billion, followed by Texas with $898.5 million, New York with $593.3 million, and Illinois with $506 million. Sheet metal product sales are expected to account for 51.3% of industry revenue in 2012. Sheet metal products are used in virtually all phases of building construction and have many uses in improvements and repairs for existing structures. Sheet metal is used to install and maintain heating, ventilation and air-conditioning duct systems; roofs; siding; rain gutters; downspouts; and skylights. Some products manufactured in this segment include awnings, canopies, casings, chutes, ducts, furnace casings, gutters and ventilators Sheet metal demand in the US is forecast to cross $20 billion by 2016, following annual gains of over five percent from 2011.
