H-beams: The flanges (side sections) are wider and have parallel inner and outer surfaces, resulting in superior cross-sectional properties. Due to their strong bending resistance and ease of construction (easy to bolt together), they have become the mainstream choice for modern steel structures, especially suitable for columns and beams subjected to heavy loads.

I-beams: The inner surface of the flanges has a slope, and the cross-sectional width is relatively narrower. A traditional type, its stability and ease of connection are slightly inferior to H-beams, but it is still used in some specific scenarios or renovation projects.

Ruisibo recommends: For new projects, especially those prioritizing efficiency and safety, we generally recommend using H-beams. Our team can assist you in selecting the most economical and safe specifications based on your design loads and building codes.
