Universal Beams - 1016x305x272

United Kingdom Universal Beams (UB), often called I-beams, are structural steel elements with an 'I' or 'H' shaped cross-section designed to carry high bending loads. They are primarily employed in structural engineering and construction scenarios where long spans and significant load-bearing capacity are required without excessive weight. You will commonly find them used as primary horizontal supports in multi-storey buildings, commercial warehouses, and industrial frameworks to transfer floor and roof loads to columns. They are also heavily utilized in residential renovations, such as creating open-plan living spaces by supporting upper floors when load-bearing walls are removed. Additionally, UBs serve as critical components in civil engineering projects, including bridge decks, gantries, and temporary shoring systems for deep excavations, because their design maximizes efficiency by placing the steel exactly where the bending stresses are highest.
