Aluminum profiles are manufactured using several processes, primarily extrusion, which involves forcing aluminum through a die to create specific shapes. Other processes include casting, where aluminum is poured into molds, and rolling, used to create flat sheets or plates. Machining processes like cutting, drilling, and milling are also used for further shaping and finishing. Additionally, aluminum profiles can be fabricated through bending, which shapes the material into curves or angles, and welding, which joins pieces together. Surface treatments like anodizing, painting, or powder coating are also applied to enhance appearance and durability.
