This product is hot-rolled I-beam, made of high-quality carbon structural steel by hot rolling. Its section is I-shaped, consisting of a web and top/bottom flanges with sloped inner surfaces and unequal thickness. It features simple structure, good bending resistance, and convenient processing & installation. With high dimensional accuracy, smooth surface, and good weldability, it is widely used in building beams, workshop supports, machinery bases, vehicle frames, and medium-small steel structures for mainly vertical loads and moderate spans.

Brief Difference between I-beam&H-beam
- I-beam has narrow flanges with sloped inner surfaces and unequal thickness, weak in torsion, suitable for unidirectional bending.
- H-beam has wide, uniform-thickness flanges with right angles, higher moment of inertia and better torsion resistance, ideal for large-span & heavy-load structures.
