Rectangular Tube Weight Calculator
Use this tool to calculate the theoretical weight of rectangular metal tubing (HSS) based on its dimensions, thickness, and material type.
How is Rectangular Tube Weight Calculated?
The weight of a rectangular tube, often classified as Hollow Structural Sections (HSS), is a theoretical calculation based on the volume of the material used and its density. The calculation requires four key measurements (Height, Width, Thickness, and Length) and the specific gravity of the metal.
The calculation is performed in three steps:
- Calculate the Cross-Sectional Area: This involves finding the area of the outer rectangle and subtracting the area of the inner hollow rectangle.
- Calculate Total Volume: Multiply the cross-sectional area by the total length of the tube.
- Calculate Weight: Multiply the volume by the material’s density.
If all dimensions are in meters, the formula is:
Weight (kg) = [ (H × W) - ((H - 2T) × (W - 2T)) ] × L × Density
Where: H=Height, W=Width, T=Thickness, L=Length (all in meters), Density in kg/m³.
Standard Material Densities
The calculator uses standard theoretical densities for common metals. Actual weight may vary slightly based on manufacturing tolerances and specific alloys.
| Material | Density (kg/m³) | Density (lb/ft³) |
|---|---|---|
| Carbon Steel (Standard) | 7,850 | 490 |
| Stainless Steel (304) | 8,000 | 499 |
| Aluminum (6061) | 2,710 | 169 |
| Copper | 8,960 | 559 |
