Aluminum profiles, or aluminum extruded profiles, aluminum extruded types, usually after heating aluminum ingot to a certain temperature, extruding machines and special molds are used to extrude products of various shapes. A variety of structural profile sizes and profile geometry as well as connecting elements and functional accessories are available for mechanical engineering and automation technologies for frame substructures, cladding, protective devices and functional applications. On the one hand, aluminum building profiles compete with section steel, but on the other hand, depending on the task, a mixture of the two materials can represent the best solution.
