1. What is Rectangular Tube Weight Calculation?

Rectangular tube weight calculation determines the mass of a hollow rectangular section based on its dimensions and material density. This is essential for structural design, material estimation, and cost calculation in construction and manufacturing.

2. How Does the Calculator Work?

The calculator uses the rectangular tube weight formula:

\[ Weight = \frac{Length \times (2 \times Width + 2 \times Height - 4 \times Thickness) \times Thickness \times Density}{1000} \]

Where:

\( Length \) — Length of the tube in meters (m)
\( Width \) — Outer width of the tube in millimeters (mm)
\( Height \) — Outer height of the tube in millimeters (mm)
\( Thickness \) — Wall thickness of the tube in millimeters (mm)
\( Density \) — Material density in kilograms per cubic meter (kg/m³)

Explanation: The formula calculates the cross-sectional area of the material and multiplies it by length and density to determine weight.

3. Importance of Weight Calculation

Details: Accurate weight calculation is crucial for structural engineering, transportation planning, material procurement, and cost estimation in construction and manufacturing projects.

4. Using the Calculator

Tips: Enter all dimensions in specified units. Default density is set for steel (7850 kg/m³). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 4×Thickness in the formula?
A: This accounts for the hollow section by subtracting the inner void area from the outer rectangular area.

Q2: What is the typical density for steel?
A: The density of carbon steel is approximately 7850 kg/m³, which is set as the default value.

Q3: Can I use this for other materials?
A: Yes, simply input the appropriate density value for aluminum (2700 kg/m³), stainless steel (8000 kg/m³), or other materials.

Q4: Why are some dimensions in mm and others in m?
A: This unit combination simplifies the formula and provides weight directly in kilograms without additional conversion factors.

Q5: How accurate is this calculation?
A: The calculation provides theoretical weight based on perfect geometry. Actual weight may vary slightly due to manufacturing tolerances and material variations.
