Aluminum square bars are solid, square-shaped bars made from high-quality aluminum alloys, widely used across industries such as construction, machinery, electronics, furniture, automotive, aerospace, and defense. They are primarily manufactured through extrusion or cold drawing processes, ensuring excellent dimensional accuracy and surface finish.The surface of aluminum square bars is usually finely brushed or polished, with temporary protective packaging to prevent scratches and contamination. Production adheres to international standards including GB/T 3191, ASTM B221, EN 754/755, and others.
An aluminum square bar is a solid, square-shaped bar made from high-quality aluminum alloys. It is commonly produced through extrusion or cold-drawing processes, which provide precise dimensions and smooth surfaces. Aluminum square bars are widely used in industries such as construction, machinery, electronics, automotive, aerospace, furniture, and defense.
They are available in various sizes, typically ranging from 10 mm × 10 mm up to 250 mm × 250 mm, with standard lengths from 1,000 mm to 6,000 mm. These bars come in different aluminum alloys, including 2xxx, 5xxx, and 6xxx series (e.g., 2024, 5083, 6061), and in multiple heat-treatment states such as O (annealed), H112, T3, T5, T6, and T6511, offering a balance of strength, corrosion resistance, and formability.
The surface is usually brushed or polished, and protective packaging prevents scratches during transport. Production conforms to standards like GB/T 3191, ASTM B221, and EN 754/755.
Aluminum square bars are valued for their versatility, durability, and reliability, making them ideal for structural components, engineering projects, decorative applications, and other demanding environments.
