Extruded aluminum rectangular tube from 40 × 20 to 100 × 50 mm. Used on edge, rectangular tube gives high bending stiffness for its weight — each size lists Ix and Iy for both orientations.
Place the long side vertical to maximise stiffness under vertical loads. Other sizes and walls are available on request.

Questions
How do you calculate rectangular aluminum tube weight?
Area = B·H − (B − 2t)(H − 2t) in mm²; multiply by 0.0027 for kg per metre.
