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.
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.
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
The process of perforating metal sheets has been practiced for over 150 years. In the late 19th century, metal screens were used as an efficient means of separating coal. The first perforators were laborers who would manually punch individual holes into the metal sheet. This proved to be an inefficient and inconsistent method which led to the ...
A throat-less bench shear. A bench shear, also known as a lever shear, is a bench mounted shear with a compound mechanism to increase the mechanical advantage. It is usually used for cutting rough shapes out of medium-sized pieces of sheet metal, but cannot do delicate work.
The metal embossing manufacturing process has these characteristics: The ability to form ductile metals. Use in medium to high production runs. The ability to maintain the same metal thickness before and after embossing. The ability to produce unlimited patterns, depending on the roll dies. The ability to reproduce the product with no variation.
