I-beams (or I-sections) produce name states in large “I” form. yet the core of the known I-beam as a net provides resistance to shear forces. The web consists of flanges, tapered or latitude flanges on both sides and at both ends of the web at an identical, external I-beam. Flanges provide resistance to bending moments.

In the construction industry, I beams are used as cross-sections using strength to beams. They include ceilings and / or floors separately, providing support to beams. They work extensively in the building industry to support structures. If i-beams are able to withstand bending, you must displace torque forces under the axis or length of the beam as they are not torsion resistant.

I-beams Can be used separately on trailer wheels and lift support screen and as pallets for trailers and load mats.

The size of the I-beams is related to the weight that must be supported and is for application and varies from structure to structure.

Beam Explanation:

Hope this helps:
The acronym IPE indicates: I = I-section beam, P = parallel flanges, E = European (UNI 5398).
The acronym IPE-A indicates light IPE.
The acronym HE indicates: H = H-section beam, E = European.
The letters A, B, M distinguish the various series of the same nominal size, with A indicating the light series, B the normal series and M the reinforced (UNI 5397).
The acronym HEA-A indicates light HEA.
The acronym UPN indicates: U = U-section beam U, PN = normal section (UNI 5680-73).

Beams means:

  • Parallel flange I sections IPE;
  • Wide flange beams HE;
  • Extra wide flange beams HL and HLZ;
  • Wide flange columns HD;
  • Wide flange bearing piles HP and UBP;
  • Universal beams UB;
  • Universal columns UC;
  • Taper flange I sections IPN and J.

New Dimensions for the Beams

In the EN 10365 the size range of the product series of I- and H-beams gets wider as follows:

  • IPE beams: to this family some lighter versions are add (IPE-A and -AA). In addition also heavier IPE-O and IPE-V variants enlarge the range, as well as four greater size IPE 750 profiles. Just to mention, there are already produces on the market, able to produce even super-light versions of the IPEs, identifies with the suffix –AAA and –AAAA.
  • HE wide flange beams: also this range is extended. Besides the beams already existing from the DIN, the HEB, HEA and HEM, the EN 10365 comes with the following new dimensions and designations
    • HE-AA super-light wide flange beam
    • HEC a lighter HEM beam
    • Further 16 HE-beams that are only defined by height times weight per meter.
