The Sheet Metal Workers' International Association (SMWIA) was a trade union of skilled metal workers who perform architectural sheet metal work, fabricate and install heating and air conditioning work, shipbuilding, appliance construction, heater and boiler construction, precision and specialty parts manufacture, and a variety of other jobs involving sheet metal.
For the Sheet Metal Workers, the process began with two 1999 convention resolutions that empowered the General Executive Council to change the union's name (as long as Sheet Metal Workers remained in the title) and streamlined the merger process so that a GEC-approved agreement to bring in smaller union would not require a convention vote.
Corrugated galvanised iron (CGI) or steel, colloquially corrugated iron (near universal), wriggly tin (taken from UK military slang), pailing (in Caribbean English), corrugated sheet metal (in North America), zinc (in Cyprus and Nigeria) or custom orb / corro sheet (Australia), is a building material composed of sheets of hot-dip galvanised ...
Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a roll slitter. In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its ...
CFI, a human gene that encodes the protein complement factor I; Color Fidelity Index, a measure for color rendering developed by CIE which is more detailed than the Color Rendering Index (CRI) measure; Common Flash Memory Interface, an open standard jointly developed by AMD, Intel, Sharp and Fujitsu
A medal ribbon, service ribbon or ribbon bar is a small ribbon, mounted on a small metal bar equipped with an attaching device, which is generally issued for wear in place of a medal when it is not appropriate to wear the actual medal. [1] Each country's government has its own rules on what ribbons can be worn in what circumstances and in which ...
A power shear is electrically or pneumatically powered hand tool designed to blank large pieces of sheet metal. They are designed to cut straight lines and relatively large radius curves. They are advantageous over a bandsaw because there is not a size limit. Large versions can cut sheet metal up to 12 gauge. [5]
For sheet metal forming analysis within the metal forming process, a successful technique requires a non-contact optical 3D deformation measuring system. The system analyzes, calculates and documents deformations of sheet metal parts, for example. It provides the 3D coordinates of the component's surface as well as the distribution of major and ...
