Cross section diagram of standard strut channel. Basic strut channel comes in the open box section 1 + 5 ⁄ 8 in (41 mm) square. A half height 1 + 5 ⁄ 8 in × 13 ⁄ 16 in (41 mm × 21 mm) version is also available, used mostly where mounted directly to a wall as it has significantly less stiffness and ability to carry loads across an open space or brace.
Structural steel. Structural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section. Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices ...
A hot-rolled HSS-box section cut open with a bandsaw, demonstrating residual stress. A hollow structural section (HSS) is a type of metal profile with a hollow cross section. The term is used predominantly in the United States, or other countries which follow US construction or engineering terminology. HSS members can be circular, square, or ...
In 1849, the method of producing an I-beam, as rolled from a single piece of wrought iron, [1] was patented by Alphonse Halbou of Forges de la Providence in Marchienne-au-Pont, Belgium. [ 2 ] Bethlehem Steel , headquartered in Bethlehem, Pennsylvania , was a leading supplier of rolled structural steel of various cross-sections in American ...

Channel iron deposits are an important source of iron ore, with the deposits at Yandi and Robe River accounting for approximately 47% of iron ore mined from the Hamerley Iron province. Although channel iron deposits are typically low-grade at 53% to 57% Fe in-situ, they are composed of goethite-limonite which are hydrated iron oxide species.
Pig iron, also known as crude iron, is an intermediate good used by the iron industry in the production of steel. It is developed by smelting iron ore in a blast furnace . Pig iron has a high carbon content, typically 3.8–4.7 %, [ 1 ] along with silica and other dross , which makes it brittle and not useful directly as a material except for ...
The Manning formula or Manning's equation is an empirical formula estimating the average velocity of a liquid in an open channel flow (flowing in a conduit that does not completely enclose the liquid). However, this equation is also used for calculation of flow variables in case of flow in partially full conduits, as they also possess a free ...
