Steel is the most widely used construction material in the world today. Its strength-to-weight ratio, toughness, flexibility, pliability, eco-friendliness, and plain aesthetic appeal have, during the 100-plus years since its invention, proven steel as the essential structural part of practically every substantial commercial structure around the world. From highrises to bridges, automobiles to ships, pipelines to rocket gantries, the sturdiness and flexibility of steel makes the fixtures of modern civilization possible.
Structural steel is the most preferred framework material for non-residential buildings on the globe. Steel members, known as beams and columns, constitute the bone structure of the building supporting all of the other parts of the building.
In the majority of developed countries, the shapes available are set out in published standards, Common structural shapes including:
I-beam (I-shaped cross-section – in the uk these include Universal Beams (UB) and Universal Columns (UC); in Europe it includes the IPE, HE, HL, HD and other sections; in the US it includes Wide Flange (WF) and H sections) also known as H-beam, W-beam (for “wide flange”) Universal Beam (UB) Rolled Steel Joist (RSJ), or double-T (especially inPolish Bulgarian Spanish Italian and German), is a beam with an I- or H-shaped cross-section. The horizontal elements of the “I” are known as flanges, while the vertical element is termed the “web”. I-beams are usually made of structural steel and are used in construction and civil engineering.
HSS-Shape (Hollow structural section also known as SHS (structural hollow section) and including square, rectangular, circular (pipe) and elliptical cross sections)
A hollow structural section is a kind of metal profile having a hollow tubular cross-section. The phrase is used mostly in USA, or some other countries which follow US construction or engineering terminology
HSS members can be circular, square, or rectangular sections, although other shapes are available, such as elliptical. HSS is simply made up of structural steel per code. HSS is usually incorrectly introduced as hollow structural steel. Rectangular and square HSS are also frequently called tube steel or structural tubing. Circular HSS are occasionally wrongly labeled steel pipe while correct steel pipe is actually dimensioned and classed differently from HSS. (HSS measurements are according to exterior size of the profile, while pipes are basically dimensioned based on interior diameters. The corners of HSS are heavily rounded, which has a radius which is approximately twice the wall thickness. The wall thickness is uniform around the section.
Angle Iron(L-shaped cross-section)
An Angle Iron is a flat metal rod that has been folded to a 90-degree angle along its length, resulting in an L-shaped piece. For Equal Angles the two sides of the angle are of equal length, with unequal length of the 2 sides are Unequal Angle. Heavier Angle Iron is often used as a structural element in buildings and bridges, while lighter Angle Iron is used for a variety of supports such as an adjustable bed frame.
Structural channel, U channel, Tee (T-shaped cross-section), Steel Bar are also widly used Structural steel in the manufacture and fabrication of a broad range of engineered products, furniture making, machinery manufacturing, shipbuilding, railway spare parts, iron towers, and boilers, etc.
There are many factors considered when choosing a construction material. Cost is commonly the controlling element; however, other considerations such as weight, strength, constructability, availability, sustainability, and fire resistance will be taken into account before a final decision is made
Most construction projects need hundreds of different materials. Many commercial and industrial structures are mainly built using either structural steel or reinforced concrete. When building a structure, you must decide which, if not both, material is most suitable for the design. There are numerous points considered when choosing a construction material. Cost is commonly the controlling element; however, other considerations such as weight, strength, constructability, availability, sustainability, and fire resistance will be taken into account before a final decision is made.
