Aluminium Square Pipe Weight Calculator
Enter the dimensions and material properties to calculate the weight of your aluminium square pipe.
Calculation Results
The weight of an aluminium square pipe is calculated by first finding the cross-sectional area of the metal (outer area minus inner area), then calculating the volume of the pipe, and finally multiplying the volume by the density of aluminium.
Cross-Sectional Area (A_cs) = (Outer Width)² – (Outer Width – 2 * Wall Thickness)²
Volume (V) = A_cs * Pipe Length
Weight (W) = Volume * Density
Note: Units are converted to ensure consistency (e.g., mm to cm for density calculation).

What is Aluminium Square Pipe Weight Calculation?
The aluminium square pipe weight calculator is a specialized tool designed to accurately determine the mass of a hollow square section made from aluminium. This calculation is crucial for various industries, including construction, manufacturing, engineering, and fabrication, where precise material estimation is vital for project planning, cost management, and structural integrity. Unlike simple volume calculations, this tool accounts for the hollow nature of the pipe and the specific density of aluminium alloys, providing a realistic weight figure.
Who should use it?
- Engineers and designers specifying materials for projects.
- Procurement and purchasing departments estimating material needs.
- Fabricators and manufacturers calculating raw material requirements and shipping costs.
- Students and educators learning about material science and engineering principles.
- DIY enthusiasts planning projects involving aluminium square tubing.
Common misconceptions about aluminium pipe weight often revolve around underestimating the impact of wall thickness or assuming a uniform density across all aluminium alloys. This calculator helps clarify these points by allowing users to input specific dimensions and select the appropriate density.
Aluminium Square Pipe Weight Formula and Mathematical Explanation
The calculation of aluminium square pipe weight involves several steps, ensuring accuracy by considering the geometry and material properties. The core principle is to determine the volume of the aluminium material itself and then multiply it by its density.
Step-by-Step Derivation:
- Calculate the Area of the Outer Square: This is simply the outer width squared.
- Calculate the Area of the Inner Square (Hollow Space): The inner width is the outer width minus twice the wall thickness. This inner width is then squared.
- Calculate the Cross-Sectional Area of the Aluminium: Subtract the inner square area from the outer square area. This gives the area of the aluminium material in the pipe's cross-section.
- Calculate the Volume of the Pipe: Multiply the cross-sectional area by the length of the pipe. It's essential to ensure consistent units here. If dimensions are in mm, the length should also be in mm.
- Convert Units for Density: Aluminium density is typically given in g/cm³ or kg/m³. To use the density value correctly with dimensions in mm, conversions are necessary. For example, 1 cm³ = 1000 mm³. So, a density of 2.7 g/cm³ is equivalent to 0.0027 g/mm³. Alternatively, convert all dimensions to cm first.
- Calculate the Weight: Multiply the volume (in consistent units, e.g., cm³) by the density (in g/cm³). The result will be in grams, which can then be converted to kilograms or tonnes.
Variable Explanations:
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Outer Width (A) | The external dimension of one side of the square pipe. | mm | 10 – 500+ |
| Wall Thickness (t) | The thickness of the aluminium material forming the pipe wall. | mm | 1 – 20+ |
| Pipe Length (L) | The total length of the square pipe section. | mm | 100 – 6000+ |
| Aluminium Density (ρ) | The mass per unit volume of the specific aluminium alloy used. | g/cm³ | 2.65 – 2.85 (common alloys) |
| Cross-Sectional Area (A_cs) | The area of the aluminium material in the pipe's cross-section. | mm² or cm² | Varies |
| Volume (V) | The total volume occupied by the aluminium material in the pipe. | mm³ or cm³ | Varies |
| Weight (W) | The total mass of the aluminium square pipe. | g, kg, or tonnes | Varies |
Practical Examples (Real-World Use Cases)
Understanding the aluminium square pipe weight calculator is best done through practical examples:
Example 1: Structural Frame Component
A construction company is building a lightweight frame for a modular building. They need to calculate the weight of several aluminium square pipes with the following specifications:
- Outer Width (A): 100 mm
- Wall Thickness (t): 5 mm
- Pipe Length (L): 6000 mm (6 meters)
- Aluminium Density (ρ): 2.7 g/cm³ (Standard Aluminium)
Calculation using the tool:
- Outer Area = 100 mm * 100 mm = 10000 mm²
- Inner Width = 100 mm – (2 * 5 mm) = 90 mm
- Inner Area = 90 mm * 90 mm = 8100 mm²
- Cross-Sectional Area (A_cs) = 10000 mm² – 8100 mm² = 1900 mm²
- Convert A_cs to cm²: 1900 mm² / 100 = 19 cm²
- Volume (V) = 19 cm² * 600 cm (6000 mm converted to cm) = 11400 cm³
- Weight (W) = 11400 cm³ * 2.7 g/cm³ = 30780 g
- Convert to kg: 30780 g / 1000 = 30.78 kg
Result Interpretation: Each 6-meter length of this aluminium square pipe weighs approximately 30.78 kg. This information is vital for calculating the total material needed for the frame, estimating transportation logistics, and ensuring the structural design can support the combined weight.
Example 2: Custom Furniture Fabrication
A furniture designer is creating a modern table frame using aluminium square tubing. They need to determine the weight for shipping and handling:
- Outer Width (A): 40 mm
- Wall Thickness (t): 2 mm
- Pipe Length (L): 1500 mm (1.5 meters)
- Aluminium Density (ρ): 2.7 g/cm³
Calculation using the tool:
- Outer Area = 40 mm * 40 mm = 1600 mm²
- Inner Width = 40 mm – (2 * 2 mm) = 36 mm
- Inner Area = 36 mm * 36 mm = 1296 mm²
- Cross-Sectional Area (A_cs) = 1600 mm² – 1296 mm² = 304 mm²
- Convert A_cs to cm²: 304 mm² / 100 = 3.04 cm²
- Volume (V) = 3.04 cm² * 150 cm (1500 mm converted to cm) = 456 cm³
- Weight (W) = 456 cm³ * 2.7 g/cm³ = 1231.2 g
- Convert to kg: 1231.2 g / 1000 = 1.23 kg
Result Interpretation: Each 1.5-meter piece of this aluminium square pipe weighs about 1.23 kg. This allows the designer to accurately quote shipping costs and manage inventory for their custom furniture pieces.

Key Factors That Affect Aluminium Square Pipe Weight Results
Several factors influence the calculated weight of an aluminium square pipe. Understanding these can help in refining your calculations and making informed decisions:
- Outer Dimensions (Width & Length): This is the most direct factor. Larger outer width and longer pipe length directly increase the volume of material, thus increasing the weight. This is a linear relationship.
- Wall Thickness: A thicker wall means more aluminium material per unit length, significantly increasing the weight. Even small changes in wall thickness can have a noticeable impact on the total weight.
- Aluminium Alloy Density: Different aluminium alloys have slightly different densities. While 2.7 g/cm³ is common, specialized alloys might be denser or less dense. Using the correct density for the specific alloy is crucial for accurate weight calculation.
- Manufacturing Tolerances: Real-world pipes may have slight variations in dimensions (outer width, wall thickness) due to manufacturing tolerances. These minor deviations can lead to small discrepancies in the actual weight compared to the calculated weight.
- Hollow vs. Solid: This calculator is specifically for hollow pipes. A solid aluminium square bar of the same outer dimensions would be significantly heavier due to the absence of a hollow core.
- Surface Finish and Coatings: While usually negligible for weight calculations, heavy coatings or surface treatments could add a minimal amount of weight. However, for standard aluminium pipes, this is typically not a significant factor.
- Temperature Effects: Aluminium, like most materials, expands and contracts with temperature. While this affects volume slightly, the change in weight is negligible for practical engineering purposes at typical ambient temperatures.
