China Steel I Beam Suppliers and Factory - High-Quality Universal Beams for Construction and Engineering

Product Overview:
I-beam, commonly referred to as a steel beam, is recognized in English as Steel I Beam or Universal Beam. This long, hot-rolled steel section features a standard I-shaped cross-section, characterized by a central vertical web and two horizontal flanges at the top and bottom. Manufactured according to national standards such as GB/T 706-2016, as well as international specifications like EN, ASTM, and JIS, our I-beams are primarily produced through hot rolling. For larger or non-standard sizes, our products can be custom fabricated through steel plate welding, while light-duty options can be processed via cold bending. As a leading factory and supplier in China, we ensure that our I-beams meet rigorous quality standards to fulfill a variety of construction and engineering needs.
