Hollow Section Weight Calculator
Calculate RHS/SHS hollow section mass from dimensions, length, and density.
A QUICK WALKTHROUGH
How to use this tool
- Enter dimensions, length, and density.
- Calculate the estimated linear and total mass.
Formula and scope
A = 2t(W + H − 2t) mm²; kg/m = A × 10⁻⁶ × ρ; total kg = kg/m × L Ideal sharp-corner thin-wall assumption; structural capacity is outside scope.
Input limits
Enter finite positive values within the limits; wall thickness must satisfy 2t < min(W, H).
GOOD TO KNOW
Common questions
Can this calculate a square tube?
Yes. Set W and H to the same value for an SHS.
