Aluminum profiles are extruded stock shapes of aluminum. These profiles are the shapes that the extruded aluminum products take the form of; for instance, a t-shaped aluminum profile is used in order to fabricate an extruded aluminum beam or extruded aluminum trim. Additional aluminum profiles include different aluminum shapes such as trim caps, rods, angles, bars and channels, which provides a small sample of the wide range of configurations and sizes that aluminum profiles are available in.

Aluminum profiles are formed during the extrusion process, in which round aluminum stock called "billets" or "logs" are pressed by a ram through a die, which is a hollow profile that shapes the aluminum into a specific extruded shape as the billet is squeezed through. Aluminum profiles can be made using two different types of extrusion process: indirect extrusion and direct extrusion. Direct extrusion holds the die stationary while the ram forces the aluminum alloy through the die opening, while indirect extrusion holds the die stationary as the hollow ram moves into the stationary billet from one end, forcing the metal to flow through the die. In addition, extrusion processes include hot extrusion, cold extrusion and warm extrusion.

In cold extruding, aluminum billet is pressed through the die at room temperature or near room temperature. Warm extruding, or forging, is done on billets brought to temperature ranges between 800 and 1800 degrees F. Hot extrusions are performed on aluminum which has been fully plasticized by heat and is often performed in a vacuum to avoid oxidation. After an aluminum profile has been extruded, it is straightened by a stretcher.

the use of high paint, up to 95% or even 100%. Due to the low solid content of the bath, the viscosity is small, the coating is brought out less paint, especially the application of ultrafiltration technology, the implementation of the coating process closed cycle, the paint recovery rate is high.
