Stainless Steel Square Tube Weight Calculator

Summary

Enter outer side, wall thickness, and length to get the exact weight of a stainless steel square hollow tube.

How it works

1. Enter the outer side length of the square tube in millimeters.
2. Enter the wall thickness in millimeters (must be less than half the outer side).
3. Enter the tube length in meters.
4. Select the stainless steel grade to use the correct density.
5. Click Calculate to see the total weight in kg and lb, plus the linear mass in kg/m.

Use cases

• Estimate material weight for structural fabrication projects.
• Calculate freight and shipping weight for square tube orders.
• Compare weight of different wall thicknesses for design optimization.
• Verify supplier weight declarations against standard formulas.
• Plan load-bearing capacity for frames and supports.
• Generate quick BOM weight entries for engineering drawings.
