Catalogue calculations use the published kg/m for the selected page-specific profile. Actual extrusion mass can still vary with production tolerance, finish, fabrication, and measurement.
Calculation method
How profile weight is estimated
For a catalogue profile, the calculator uses the kg/m published for that exact profile. For a custom section, it converts cross-section area and the selected material density into a theoretical kg/m.
The result is for early planning. Confirm the drawing, alloy, tolerances, finish, fabrication and measured weight before specifying or ordering.
01 / Section area
Enter the area from a drawing, or calculate it from a solid rectangle, round bar, rectangular tube or round tube. Tube area is the outside area less the inside void.
02 / Mass per metre
kg/m = area (mm²) × density (kg/m³) ÷ 1,000,000
The conversion accounts for millimetres squared in the section area and metres in the length.
03 / Cut pieces and order
kg/piece = kg/m × cut length (m)
Order kg = kg/piece × quantity
Worked example
A 100 mm² section at 2,700 kg/m³ is 0.270 kg/m. At 2 m per piece and 100 pieces, the theoretical order mass is 54 kg.
