![]() These sections have parallel flanges, as opposed to the varying thickness of RSJ flanges which are seldom now rolled in the UK. British and European standards also specify Universal Beams (UBs) and Universal Columns (UCs). A common type of I-beam is the rolled steel joist (RSJ)-sometimes incorrectly rendered as reinforced steel joist. I-beams are commonly made of structural steel but may also be formed from aluminium or other materials. ![]()
