Aluminum Dimensions – Everything You Need to Know

Why are dimensions important for aluminum?

The dimensions of aluminum profiles, sheets, and tubes play a crucial role in selecting the right material for technical applications. Whether in mechanical engineering, construction, or automotive technology, precise measurements are essential for stability, fit, and processing.

Common Dimensions and Tolerances

Aluminum is available in many forms, including sheets, plates, profiles, and tubes. Standard sizes vary depending on the alloy and manufacturer:

Aluminum sheets: 0.5 mm to 10 mm thickness
Aluminum plates: 10 mm to 100 mm thickness
Flat bar: 10 x 2 mm to 150 x 10 mm
Aluminum round bar: 4 mm to 160 mm
Aluminum square bar: 4 x 4 mm to 100 x 100 mm
Aluminum hex bar: 7 mm to 50 mm
Round tubes: 4 mm to 120 mm diameter
Square tubes: 10x10 mm to 120x120 mm
Angles: 10 x 10 mm to 150 x 100 mm
U-profiles: 10 x 10 x 10 mm to 80 x 80 x 80 mm
T-profiles: 15 x 15 mm to 60 x 100 mm
Z-profiles: 17 x 25 x 17 mm to 40 x 40 x 40 mm

Tolerances and Standards

Dimensional accuracy is regulated by EN 755-9 (for profiles) and EN 485-4 (for sheets and plates). Depending on the application, tight or generous tolerances may be required.

In the product configurator, we offer you the option to agree to a length tolerance of approx. 5 mm. If you need your profile accurate to the millimeter, select "No" here.
