Below is a list of Aluminum Extrusions manufacturers from Linthicum Heights, Maryland. Aluminum extrusions are linear aluminum products highly valued in a wide spectrum of structural applications due to aluminum's high strength-to-weight ratio and the cost effectiveness of the metal extrusion process. Like other types of metal extrusions, extruded aluminum is either hot extruded or cold extruded through a die, shaping aluminum stock into various types of extruded aluminum shapes, such as angles and beams, aluminum channels, aluminum profiles or aluminum extruded tubing.
