What Are the Sizes of UB?

Universal beams are long, robust, and powerful structural elements with an I- or H-shaped cross-section. They are essential for maintaining the structural integrity and providing primary support in building construction. These steel beams are also known as load-bearing steels, UBs, I-beams, I-sections, H-beams, RSJs, and RSJ beams.

Large-scale construction projects typically utilize universal beams due to their exceptional ability to support substantial loads. These beams are frequently employed to lend support and stability to a building's skeletal structure.

The beams are fabricated from high-quality steel to ensure the stability of the construction. The cross-section of a universal beam maintains an I- or H-shape along its entire length, and the height is always equal to or greater than the width at any point, resulting in uniform dimensions from end to end.

Applications of UBs

Because of its strength and adaptability, universal beams are widely used in a wide range of architectural and building projects. Among the frequently used applications are:

  • Load-bearing Support: UBs are extensively employed in the construction of buildings, particularly in the floors, roofs, and bridges.
  • Frameworks: They give both residential and commercial buildings a strong foundation.
  • Reinforcement: To ensure the stability and lifespan of existing structures, UBs are frequently used in renovation projects.
  • Tailored Solutions: Because UBs are flexible, they may be tailored to specific construction requirements, including those of big industrial structures or intricate architectural plans.

Different Sizes and Weights of Universal Beams

Universal Beams are available in a variety of diameters and weights to meet various structural needs. Generally speaking, a UB's depth, width, and weight per unit length determine its size. The ability of the UB to withstand bending and deformation under stress increases with its depth.
