Both Columns and Universal Beams (UB) or I-beams are commonly referred to "I-Sections" or "H-Sections". Universal Columns are identified by their similar depth to width ratio which makes them ideal for use as columns and also as beams where a load bearing member is required and is limited by space, which is often the case in residential projects. The last number in the description is the weight of the column in kg per m. Universal Columns are the most widely used structural steel section.
