I-beam

An I-beam, also known as a universal beam, H-beam, or rolled steel joist (RSJ), is a structural steel shape with a cross-section resembling the capital letter “I”. It consists of a vertical web and horizontal flanges, designed to resist bending and shear forces with high efficiency. The geometry of the I-beam allows it to carry heavy loads over long spans while minimizing material usage, making it the preferred choice for skyscrapers, bridges, industrial buildings, and infrastructure projects worldwide. I-beams are manufactured through hot-rolling or welding processes, with dimensions and weight per meter standardized under international norms such as ASTM A992, EN 10025, and JIS G3101. Their versatility, strength-to-weight ratio, and cost-effectiveness have made them indispensable in modern engineering.
