Square Pipe Weight Calculator (Square Tube)
Calculate exact mass for Square Hollow Sections (SHS) and square pipes
- Enter the Outer Size (A) of the square tube (width = height).
- Enter the Wall Thickness (t).
- Enter the Length (L). You can freely mix units (mm, cm, in, m).
- Select your material and click “Calculate”.
Precision Math: This calculator finds the exact volume of the square profile using the geometric formula: Area = A² - (A - 2t)². It subtracts the hollow inner core from the solid outer boundary before applying the material density.

The Ultimate Square Pipe Weight Calculator
In modern construction, architectural framing, and heavy machinery manufacturing, square metal tubing offers a superior strength-to-weight ratio compared to solid bars, while providing flat surfaces that are significantly easier to weld and bolt than round pipes. However, accurately determining the mass of your materials using a Square Tube Weight Calculator is absolutely vital for pricing vendor quotes, ensuring structural load limits, and managing freight logistics.
Whether you are working with aluminum framing or heavy-duty carbon steel, our interactive Square Hollow Section Weight Calculator provides flawless theoretical weight estimates to keep your fabrication projects on budget and on schedule.
The Square Steel Tube Weight Formula
To calculate the theoretical mass of any SHS (Square Hollow Section) manually, you must calculate the geometric volume of the metal profile and multiply it by the specific density of the alloy. Unlike a solid square bar, you must subtract the empty “hollow” inner core from your calculations.
The universal industrial formula powering this Square Steel Tube Weight Calculator is:
Weight = Volume × Material Density
Where ‘A’ is the outer dimension, and ‘t’ is the wall thickness.
Square Tube vs. Box Profile: What’s the Difference?
When searching for a Square Pipe Weight Calculator, you will often hear the terms “Square Tube” and “Box Profile” used interchangeably. In general fabrication:
- Square Tube / SHS: Refers specifically to a symmetrical tube where the outer width and outer height are exactly the same ($A = A$).
- Box Profile / RHS (Rectangular Hollow Section): Refers to tubing where the width and height are different (e.g., 100mm x 50mm). If you need to calculate an RHS, you can use our dedicated Box Profile Calculator.
