IPE vs IPEAA Steel Beams | Structural I Beam Comparison & Selection Guide
Publish Time: 2025-10-27 Origin: Site
In building and structural engineering, I-beams steel are key components that bear bending and shear forces. While the different types appear similar, IPE and IPEAA differ slightly in cross-sectional specifications, recommended applications, and structural properties. Choosing the right type can improve project safety and optimize construction costs.
Ⅰ. Specifications and Materials Overview
The IPE series typically covers common sizes such as IPE100–IPE270, and is often made of carbon structural steel, targeting general building and structural applications; while the IPEAA series offers lighter specifications such as IPEAA80–IPEAA200, targeting lightweight applications or those with strict weight control.
Ⅱ. Mechanical and structural differences
From a mechanical perspective, section height, web and flange widths, and cross-sectional area directly determine a beam's bending stiffness and shear load. Generally speaking, profiles with wider flanges or thicker webs at the same height can withstand greater bending moments and the risk of local buckling. IPEAA, known for its "lightweight and balanced rigidity," is suitable for structures sensitive to vibration or deformation. IPE, on the other hand, has a larger size limit and is suitable for beam-column components requiring higher load-bearing capacity.
Ⅲ. Comparison of typical application scenarios
IPE: Commonly used for factory building main beams, floor slab secondary beams, bridge components, and general structural components, it is a commonly used "general-purpose I-beam" in engineering due to its wide range of sizes and excellent balance of strength and cost-effectiveness.
IPEA: Predominantly used for lightweight design in warehouses, light-duty factories, commercial and residential structures, or as secondary structures in locations sensitive to deflection and vibration. Its thinner size combination saves material and reduces deadweight.
IPE and IPEAA each focus on larger cross-sections and stronger load-bearing capabilities, while the other offers lighter specifications and material savings.
