Product Description

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, etc., are regulated by standards in most industrialized countries.

Most structural steel shapes, such as I-beams, have high second moments of area, which means they are very stiff in respect to their cross-sectional area and thus can support a high load without excessive sagging.

Common structural shapes

The shapes available are described in many published standards worldwide, and a number of specialist and proprietary cross sections are also available.
A steel I-beam, in this case used to support timber joists in a house.

I-beam (I-shaped cross-section - in Britain 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 or W-Shape) and H sections)
Z-Shape (half a flange in opposite directions)
HSS-Shape (Hollow structural section also known as SHS (structural hollow section) and including square, rectangular, circular (pipe) and elliptical cross sections)
Angle (L-shaped cross-section)
Structural channel, or C-beam, or C cross-section
Tee (T-shaped cross-section)
 Rail profile (asymmetrical I-beam)
 Railway rail
 Vignoles rail
 Flanged T rail
 Grooved rail
 Bar, a piece of metal, rectangular cross sectioned (flat) and long, but not so wide so as to be called a sheet.
 Rod, a round or square and long piece of metal, see also rebar and dowel.
 Plate, metal sheets thicker than 6 mm or ​1⁄4 in.
 Open web steel joist

While many sections are made by hot or cold rolling, others are made by welding together flat or bent plates (for example, the largest circular hollow sections are made from flat plate bent into a circle and seam-welded)

Standards
A set of Euronorms define the shape of a set of standard structural profiles:

    European I-beam: IPE - Euronorm 19-57
    European I-beam: IPN - DIN 1025-1
    European flange beams: HE - Euronorm 53-62
    European channels: UPN - DIN 1026-1
    European cold formed IS IS 800-1

    Hollow sections - EN 10219-1 and EN 10210-1
    Pre-loadable bolts - EN 14399-1
    Non-preloadable bolts - EN 15048-1
    Fabricated steel - EN 1090 -1

 Manufacturing

Cutting workpieces to length is usually done with a bandsaw.

A beam drill line (drill line) has long been considered an indispensable way to drill holes and mill slots into beams, channels and HSS elements. CNC beam drill lines are typically equipped with feed conveyors and position sensors to move the element into position for drilling, plus probing capability to determine the precise location where the hole or slot is to be cut.

For cutting irregular openings or non-uniform ends on dimensional (non-plate) elements, a cutting torch is typically used. Oxy-fuel torches are the most common technology and range from simple hand-held torches to automated CNC coping machines that move the torch head around the structural element in accordance with cutting instructions programmed into the machine.

Fabricating flat plate is performed on a plate processing center where the plate is laid flat on a stationary 'table' and different cutting heads traverse the plate from a gantry-style arm or "bridge." The cutting heads can include a punch, drill or torch.
