HL - European extra wide flange section

Wide flange beams are commonly made of structural steel but may also be formed from aluminium or other materials. UK. Parallel flanges are easier to connect to and do away with the need for tapering washers. Tables are available to allow easy selection of a suitable steel I-beam size for a given applied load.

HL beams may be used both on their own, or acting compositely with another material, typically concrete. Design may be governed by any of the following criteria.These sections have parallel flanges, as opposed to the varying thickness of RSJ flanges which are seldom now rolled in the UCs have equal or near-equal width and depth and are more suited to being oriented vertically to carry axial load such as columns in multi-storey construction, while UBs are significantly deeper than they are wide are more suited to carrying bending load such as beam elements in floors.

A common type of European extra wide flange sections is the rolled steel joist (RSJ)—sometimes incorrectly rendered as reinforced steel joist. British and European standards also specify Universal Beams (UBs) and Universal Columns (UCs).

Wide flange beam are widely used in the construction industry and are available in a variety of standard sizes. . HL beam may be used both as beams and as columns.
