EUROPEAN STEEL SECTIONS

I Beams (I-shaped cross-section) - in Europe it includes the IPE, HE, HL, HD and other sections. European  Steel Sections are designated as Follows.

 

IPE - European steel I-beams

IPN - European standard beams

HE - European wide flange beams

HL - European extra wide flange beams

HD - European wide flange columns

HP - European wide flange bearing piles

UPE- European channel with parallel flanges

UPN- European channels with taper flanges

U - European channels with taper flange

Most steels used throughout Europe are specified to comply with the European standard EN 10025. However, many national standards also remain in force.

The dimensions are DIN Standard / Euronorm and Tolerences are EN Standard (Dimensions: DIN 1026-2:2002-10; Tolerance: EN 10279:2000).

What does IPE stand for?

I-Profile Européennes (French: European I-Beam profile)

IPE - European steel I-beams have parallel flange surfaces and height 80-600(mm): according to Euronorm 19-57; Tolerances: EN10034:1993. Also, manufacturers supply additional range of IPE from 80 mm to 750 mm height.

UN EQUAL ANGLE

Let us see the Un Equal Angle. This is same as angle section with different side length. Otherwise we can say if one leg is longer than the other then it is known as UNEQUAL angle. It is mentioned as follows

UA- Size 'A' X Size 'B' X Thickness 'C'

Example UA-200X100X10

Designation and terminology of Beams

• In India
I-beams are designated as ISMB, ISJB, ISLB, ISWB. ISMB :Indian Standard Medium Weight Beam, ISJB : Indian Standard Junior Beams, ISLB : Indian Standard Light Weight Beams, ISWB : Indian Standard Wide Flange Beams. Beams are designated as per respective abbreviated reference followed by the depth of section such as for example ISMB 450, where 450 is the depth of section in millimetres (mm). The dimensions of these beams are classified as per IS:808. (as per BIS)
• In the United States
I-beams are commonly specified using the depth and weight of the beam. For example, a "W10x22" beam is approximately 10 inches (25 cm) in depth (height when the I-beam is standing on its flanges) and weighs approximately 22 lb/ft (33 kg/m).
• In Canada
I-beams are now commonly specified using the depth and weight of the beam in metric terms. For example, a "W250x33" beam is approximately 250 millimetres (10 in) in depth (height when the I-beam is standing on its flanges) and weighs approximately 33 kg/m (22 lb/ft).

• In the United Kingdom
these steel sections are commonly specified with a code consisting of the major dimension (usually the depth)-x-the minor dimension-x-the mass per metre-ending with the section type, all measurements being metric. Therefore a 152x152x23UC would be a column section (UC = universal column) of approximately 152 millimetres (6 in) depth 152 millimetres (6 in) width and weighing 23 kg per meter length.
• In Australia
these steel sections are commonly referred to as Universal Beams (UB) or Columns (UC). The designation for each is given as the height of the beam, the type (beam or column) and then the unit metre rate (e.g., a 460UB67 is a 460 millimetres (18 in) deep universal beam that weighs 67 kg/m)
