Carbon Steel I/H Beam
Carbon Steel I/H Beams are long structural members defined by their cross-sectional shape: the I-beam has tapered flanges, while the H-beam (Wide Flange) has parallel flanges. Both are highly efficient, concentrating material in the flanges to resist heavy loads and bending. Typically made from structural carbon steels (like Q235 or A36), they are fundamental components used as support beams and columns in civil engineering, bridge construction, and commercial and industrial buildings.
