Summary
IPE is the abbreviation of European Standard Lightweight I-beam (I - peine Européenne), and the numbers after it indicate the cross-sectional height in millimeters. For example, IPE100 represents an I-beam with a height of 100mm.
IPE is the abbreviation of European Standard Lightweight I-beam (I - peine Européenne), and the numbers after it indicate the cross-sectional height in millimeters. For example, IPE100 represents an steel i-beams with a height of 100mm.
Model range: Common models range from IPE80 to IPE770, with a total of more than 20 models. Small specifications include IPE80, IPE100, IPE120, etc.; the medium specifications are IPE180, IPE200, IPE220, etc.; The large specifications are IPE300, IPE360, IPE400, etc. For example, the IPE330 is a large-scale model that plays an important role in structural support in industrial and architectural scenarios.
The outer surface of the flange is parallel and unsloping, which greatly facilitates bolting or welding operations. In actual engineering installation, it can reduce the difficulty of installation and improve construction efficiency.
The symmetrical distribution of the "I" zigzag cross-section, the center of gravity line coincides with the center of the section, so that the
I-beam produces an eccentric bending moment under force, which ensures the uniformity of the force and the stability of the structure, and has the advantages of excellent lightweight and high bending performance.
Common materials: including S235, S275, S355, etc. Different materials correspond to different yield strengths, suitable for different engineering scenarios. For example, S235 has a yield strength of 235MPa and is often used in lightweight non-load-bearing structures; S275 has a yield strength of 275MPa and is suitable for medium-load scenarios; S355 has a yield strength of 355MPa and is widely used in high-load structures due to its high strength.
IPEA series
Naming Conventions: The IPEA series is closely related to the IPE series, usually indicated by adding an "A" in front of the corresponding IPE model. For example, IPEA100 is a variant of IPE100.
Model range: The model range of the IPEA series corresponds to the IPE series, from IPEA80 to IPEA770 and more. However, compared with the IPE series, the IPEA series is not as extensive in practical applications.
Section Characteristics: The section shape of the IPEA series is the same as that of the IPE series, both in the shape of an "I". But in size, the IPEA series is slightly smaller than its IPE counterpart. Taking IPE180 and IPEA180 as an example, the IPE180 measures 180×91×5.3×8, while the IPEA180 size is 177×91×4.3×6.5. This difference in size makes the IPEA series uniquely valuable in scenarios with special space requirements or relatively small loads.
Common Materials: Similar to the IPE series, commonly used materials include S235JR, S275JR, S355JR, etc. This means that the IPEA series can match the IPE series in terms of material performance, but only in size specifications to meet diverse engineering needs
