Top 10 i-beam Factory in China 2025

Introduction to I - beam

An I - beam, also known as H - beam, W - beam (for "wide flange"), universal beam (UB), rolled steel joist (RSJ), or double - T (especially in Polish, Bulgarian, Spanish, Italian and German), is a beam with an I or H - shaped cross - section. The horizontal elements of the "I" are known as flanges, while the vertical element is called the web. The I - beam shape is very efficient for carrying both bending and shear loads in the plane of the web. Due to its high strength - to - weight ratio, it is widely used in construction, machinery manufacturing, bridge building, and other engineering fields. In China, with the rapid development of infrastructure and industrial construction, the demand for high - quality I - beams has been increasing steadily, leading to the growth of many excellent I - beam manufacturing factories.
