Leading Aluminum Beam Manufacturers

As a result, aluminum beams will last a long time without much maintenance or upkeep. They come in many different shapes, including unequal or equal I beams, which are the most widely used, channels, which are unrounded and C-shaped, H beams and T beams. The aluminum beam fabrication process is fairly similar to other extruded aluminum shapes such as aluminum bars or rods. In addition, aluminum beams are joined together by means of rivets or bolts and may be welded if necessary. To begin, aluminum beams are manufactured by the extrusion process, in which long structural shapes are produced when heated or room temperature metal billets are forced through a die. In order to maintain and increase strength properties, manufacturers of aluminum beams often put them through post-forming heat treatment process like anodizing, when the aluminum is oxidized in a chemical bath and forms a permanent strong outer coating. They are also tempered, a form of heat treatment where the metal is strengthened when the intermetallic particles are precipitated. While steel beams are used more as the major structural frames for buildings because of their weight capabilities, aluminum beams, which are not as tough, are used for applications that don't require such high strength. Some of these low-strength applications include structural components for residential homes such raftings, awnings and gutters as well as industrial applications such as safety rails and more.
