As a widely used aluminum profile shape, aluminum tubes are available in square, rectangular and round shapes in a range of sizes based on the outside dimensions. The tube’s strength is a factor of the aluminum alloy used, the thickness of the walls, and the size of the tube. Tubes of larger diameters can withstand less stress and pressure.

Round tubes are available in the widest variety of sizes, from an outer diameter of 5/8 inch to 16 inches and wall thicknesses of 1/16 inch to 1 inch. Round aluminum tubes are most commonly produced from 6061 alloy to give them superior strength, a good surface finish, excellent resistance to corrosion from sea water and atmosphere. In addition, they are heat-treatable and easy to weld, cut, form and machine. Used extensively in the manufacture of marine and automotive components, round tubes play a major role in many different types of construction projects.

Rectangular and square aluminum tubes are usually available in fewer size variations than round tubes. With square defined corners on both the inside radius and outside radius, rectangular and square tubes typically range in size from 1/2 inch to 8 inches per side, with wall thicknesses of 1/8 inch for smaller tubes to ½ inch for larger tubes.

Produced from both 6061 and 6063 alloy, rectangular and square tubes make excellent exposed components for architectural use due to their superior finishing qualities. Tubes from 6061 alloy are ideally suited for structural components because the alloy offers a high resistance to corrosion from environmental conditions. It is the most versatile and least expensive of the heat-treatable aluminum alloys and is used where appearance and moderate strength are needed.
