A Rectangular Hollow Tube, often termed as a rectangular hollow section (RHS), is a type of metal profile with a hollow tubular cross-section. It’s frequently used in construction and structural applications, where its weight plays a pivotal role. To help professionals and enthusiasts alike determine this weight easily, we use a tool known as the Rectangular Hollow Tube Weight Calculator. This invaluable tool incorporates a specific formula to provide an accurate weight estimation of the tube based on its dimensions and material density.

Understanding the Rectangular Hollow Tube Weight Calculator

The Rectangular Hollow Tube Weight Calculator is an essential tool designed to provide quick, accurate weight estimations of rectangular hollow tubes. It works based on the precise measurements of the tube’s dimensions and its material’s density. By using this calculator, professionals can efficiently determine the weight of these tubes, which is critical for various structural calculations, transportation logistics, and cost estimations.

The Rectangular Hollow Tube Weight Formula and Its Variables

The calculator operates using a specific formula:

W = (H*W – (W-t * H-t))*L*D


  • W represents the Rectangular Hollow Tube Weight in lbs.
  • H is the height of the tube in inches.
  • W is the width of the tube in inches.
  • t stands for the thickness of the tube wall in inches.
  • L denotes the length of the tube in feet.
  • D refers to the density of the tube in lbs/ft^3.

To calculate the weight of a hollow rectangular tube, the calculator first finds the difference between the total volume and the inner volume, then multiplies the result by the material’s density.

A Detailed Example

Let’s illustrate this formula’s operation with a concrete example. Suppose we have a rectangular hollow tube with the following specifications:

  • Width: 6 inches
  • Height: 2 inches
  • Wall Thickness: 0.7 inches
  • Length: 8 feet
  • Material Density: 333 lbs/ft^3

Substituting these values into the formula:

W = (2*6 – (6-0.7 * 2-0.7))*8*333 = 1134.42 lbs

Hence, the weight of this specific rectangular hollow tube is 1134.42 lbs.
