What is Aluminum L Profile?
Aluminum L Profile is a type of L-shaped aluminum extrusion featuring a 90° angle, available in equal or unequal leg designs. It is widely used as a structural and decorative component in industrial, architectural, furniture, and electronic applications. Made from alloys such as 1050, 1070, 3103, 6060, and 6061, it offers excellent strength, corrosion resistance, and ease of machining. Aluminum L Profiles come in various states (O, T5, T6/T651) and sizes, typically with wing lengths from 20 mm to 130 mm, thicknesses from 0.8 mm to 5 mm, and customizable lengths. Surface treatments include anodizing (Type II/III), powder coating, and natural oxidation. They are ideal for frames, supports, edge protectors, and decorative edges, combining lightweight design with durability and versatility for multiple industrial and architectural uses.
