The structural channel, C-channel or parallel flange channel (PFC), is a type of (usually structural steel) beam, used primarily in building construction and civil engineering. Its cross section consists of a wide "web", usually but not always oriented vertically, and two "flanges" at the top and bottom of the web, only sticking out on one side ...
It is numbered with a stylized flag symbol surrounding the number (or sometimes a delta symbol). A general note applies generally and is not called out with flags. 2. Find number: "FN" meaning "find number" refers to the ordinal number that gives an ID tag to one of the constituents in a parts list (list of materials, bill of materials).
Anchor channels, invented by Anders Jordahl in 1913, are steel channels cast flush in reinforced concrete elements to allow the installation of channel bolts for the fastening of components. Anchor channels consist of steel C-shaped channels and anchors (mostly headed studs ) which are connected to the channel by welding or riveting/forging.
I-beams are typically made of structural steel and serve a wide variety of construction uses. The horizontal elements of the Ɪ are called flanges , and the vertical element is known as the "web". The web resists shear forces , while the flanges resist most of the bending moment experienced by the beam.
Air conditioning – (often referred to as 'AC, A/C, or air con) [2] is the process of removing heat and moisture from the interior of an occupied space to improve the comfort of occupants. Air conditioning can be used in both domestic and commercial environments. All-in ballast – Alloy –is a combination of metals or of a metal and another ...
In steel building construction, secondary members such as purlins (roof) and girts (wall) are frequently cold-formed steel C, Z or U sections, (or mill rolled) C sections. Cold formed members can be efficient on a weight basis relative to mill rolled sections for secondary member applications.
Channel or C section girts bolted to plate cleats welded to a portal column in an industrial building. In architecture or structural engineering, a girt, also known as a sheeting rail, is a horizontal structural member in a framed wall. Girts provide lateral support to the wall panel, primarily to resist wind loads. [citation needed]
Cold-formed steel framing (CFSF) refers specifically to members in light-frame building construction that are made entirely of sheet steel, formed to various shapes at ambient temperatures. The most common shape for CFSF members is a lipped channel, although "Z", "C", tubular, "hat" and other shapes and variations have been used.
