Rectangular Hollow Section Weight Calculator

Calculate the Weight of Rectangular Hollow Sections (RHS)

This calculator provides a precise way for engineers, fabricators, and project managers to determine the weight of Rectangular Hollow Sections (RHS), also known as rectangular pipes. Accurate weight information is crucial for structural design, cost estimation, and transportation planning.

How It Works

The tool calculates weight by determining the volume of steel in the section and multiplying it by the density of mild steel. You'll need to provide the dimensions in millimeters (mm):

Height and Width: The outer dimensions of the rectangular section.

Wall Thickness: The thickness of the section's wall.

Length: The total length of the section.

Density: Defaults to 7850 kg/m³ for mild steel, but can be adjusted for other materials.

By calculating the volume of the outer section and subtracting the inner hollow volume, the tool finds the precise material volume. This is then multiplied by the density to give you a reliable weight in kilograms (kg), ensuring your project planning is built on solid data.
