The Rectangular Hollow Tube Weight Calculator is an essential tool for engineers, builders, and DIY enthusiasts. It simplifies the process of determining the weight of hollow rectangular tubes, which are widely used in construction, mechanical projects, and manufacturing.

This calculator integrates critical parameters such as tube dimensions, material thickness, length, and density, providing accurate results. Whether you’re working with steel, aluminum, or another material, this tool helps you optimize your material usage and cost estimation effectively.

Formula

W = (H ∗ W − (W − t ∗ H − t)) ∗ L ∗ D

Variable	Description	Unit
W	Weight of the tube	Kilograms
H	External height of the tube	Millimeters
W	External width of the tube	Millimeters
t	Thickness of the material	Millimeters
L	Length of the tube	Meters
D	Material density	Kg/m³

Solved Calculations

Example 1: A rectangular hollow tube has an external height of 50 mm, an external width of 25 mm, a thickness of 3 mm, a length of 1 meter, and a material density of 7850 kg/m³.

Step	Calculation	Result
Internal dimensions	$H_{internal} = 50 – 2∗3, W_{internal} = 25 – 2∗3$	44 mm, 19 mm
Cross-sectional area difference	$(50∗25) – (44∗19)$	306 mm²
Volume	$306∗1∗10^{-6}$	0.000306 m³
Weight	$0.000306∗7850$	2.4 kg

Example 2: A hollow tube with external dimensions of 100 mm × 50 mm, thickness 5 mm, length 2 meters, and density 2700 kg/m³ (aluminum).

Step	Calculation	Result
Internal dimensions	$H_{internal} = 100 – 2∗5, W_{internal} = 50 – 2∗5$	90 mm, 40 mm
Cross-sectional area difference	$(100∗50) – (90∗40)$	1400 mm²
Volume	$1400∗2∗10^{-6}$	0.0028 m³
Weight	$0.0028∗2700$	7.56 kg
