Iron Tube Weight Calculator

Summary

Enter outer dimensions, wall thickness, and length to instantly calculate the weight of a hollow square or rectangular iron tube.

How it works

1. Enter the outer width and height of the tube in millimeters.
2. Enter the wall thickness in millimeters.
3. Select the material (mild steel / iron by default) or enter a custom density.
4. Enter the tube length in meters (or switch to millimeters).
5. The calculator instantly displays weight in kg and lbs.
6. Use the quantity field to get total weight for multiple pieces.

Use cases

• Estimate steel material costs for construction projects.
• Calculate load-bearing capacity based on tube weight.
• Plan shipping and logistics by knowing exact part weights.
• Compare wall thicknesses to find the lightest viable section.
• Verify supplier specifications for hollow structural sections.
• Size crane or rigging equipment for lifting tube bundles.
• Calculate weight of structural frames before fabrication.
• Generate cut-lists with individual and total piece weights.
