A steel fence post, also called (depending on design or country) a T-post, a Y-post, or variants on star post, is a type of fence post or picket. They are made of steel and are sometimes manufactured using durable rail steel. They can be used to support various types of wire or wire mesh. The end view of the post creates an obvious T, Y, or ...
A jack post (telepost, adjustable steel column) is a steel post used in the construction trades for temporary support of ceilings, walls and trenches . They are designed to be able to mechanically telescope to about twice their shortest length in order to span a wide variety of spaces.
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 ...
Story – A post only one story tall as in "storeyed construction" [12] also known as platform framing. Prick – 1) Same as story post, a one-story post for extra support at a particular location; 2) In a roof truss a side post. [13] Ridge – A post extending from the ground or foundation to the ridge beam.
Iron posts, if used, are a minimum 64 millimetres (2.5 in) in diameter. Bracing wire is typically smooth 9-gauge. Line posts are set to a depth of about 76 centimetres (30 in). Conversely, steel posts are not as stiff as wood, and wires are fastened with slips along fixed teeth, which means variations in driving height affect wire spacing.
Common heights include one-foot increments from 3 feet (0.91 m) to 8 feet (2.4 m), and other heights including 3 feet 6 inches (1.07 m), 10 feet (3.0 m), and 12 feet (3.7 m) although almost any height is possible. Mesh is commonly 9, 11, or 11 + 1 ⁄ 2 wire gauge. Mesh length can also vary based on need, with the standard diamond size being 2 ...
Steel never turns into a liquid below this temperature. Pure Iron ('Steel' with 0% Carbon) starts to melt at 1,492 °C (2,718 °F), and is completely liquid upon reaching 1,539 °C (2,802 °F). Steel with 2.1% Carbon by weight begins melting at 1,130 °C (2,070 °F), and is completely molten upon reaching 1,315 °C (2,399 °F).
Steel tubes are either 'black' or galvanised. The tubes come in a variety of lengths and a standard outside diameter of 48.3 mm. (1.5 NPS pipe). The chief difference between the two types of metal tubes is the lower weight of aluminium tubes (1.7 kg/m as opposed to 4.4 kg/m). Aluminium tube is more flexible and has a lower resistance to stress.
