​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.IPE and IPEAA each focus on larger cross-sections and stronger load-bearing capabilities, while the other offers lighter specifications and material savings. We can provide sample materials, cross-section mechanical data, and custom cutting services. Please contact us for project-level selection support and technical consultation.
