How Much Does a 40 × 40 × 3 Hollow Section Weigh?

A 40 × 40 × 3 mm hollow section, also known as a square hollow section (SHS), is commonly used in construction and fabrication. The weight of such a section depends on its dimensions and material density—typically steel. To calculate the approximate weight per meter, you can use the formula:

Weight (kg/m) = [(A × B) - (A - 2t) × (B - 2t)] × ρ × 0.001,
where A and B are the outer dimensions (in mm), t is the thickness, and ρ is the density of steel (usually 7.85 g/cm³).

For a 40 × 40 × 3 mm SHS, the approximate weight is around 3.24 kg per meter. This value may slightly vary depending on manufacturing tolerance and steel grade. Using a weight calculator helps ensure precision in material planning and cost estimation.

Densities of Various Metals Used in RHS

Understanding the density of different materials is crucial for accurate weight calculations. Here is a table of densities for commonly used metals in RHS:

Material	Density (kg/m³)
Steel	7850
Stainless Steel	8000
Aluminum	2700
Brass	8500
Copper	8960
Titanium	4500
Zinc	7130
Lead	11340

Weight Per Meter Calculation for RHS

One of the essential features of our RHS Weight Calculator is determining the weight per meter. This value is crucial for estimating the total material needed for your project.

The weight per meter depends on the material’s density, the external dimensions, and the wall thickness.

Example 2: Aluminum RHS

• Material: Aluminum
• Width: 80 mm
• Height: 40 mm
• Thickness: 4 mm
• Length: 4 meters

Using the same formula:

After calculation, the total weight is approximately 10.36 kg.
