⚙️ Steel Weight Calculator
Calculate weight of steel plates, bars, beams, and tubes
Default: 7850 kg/m³ (standard carbon steel)
How to Use This Calculator
Select Steel Shape
Choose the shape of your steel: plate (flat sheet), bar (round rod), beam (I-beam), or tube (hollow pipe). The calculator adjusts input fields based on your selection.
Enter Dimensions
Input the dimensions for your steel shape. For plates, enter length, width, and thickness. For bars, enter length and diameter. For beams, enter length, width, and height. For tubes, enter length, diameter, and wall thickness.
Set Steel Density
Enter the steel density in kg/m³. The default is 7850 kg/m³ for standard carbon steel. Adjust for different steel types: stainless steel (~8000 kg/m³), aluminum (~2700 kg/m³).
Calculate Weight
Click "Calculate Weight" to see the weight in kilograms, pounds, and tons. The calculator also shows the volume for reference.
Formula
Weight = Volume × Density
Where:
Plate Volume = Length × Width × Thickness
Bar Volume = π × (Diameter/2)² × Length
Beam Volume = Length × Width × Height
Tube Volume = π × (R_outer² - R_inner²) × Length
Example 1: Steel Plate (10 ft × 5 ft × 0.5 inches)
Step 1: Convert to meters: 10 ft = 3.048 m, 5 ft = 1.524 m, 0.5" = 0.0127 m
Step 2: Calculate volume: 3.048 × 1.524 × 0.0127 = 0.059 m³
Step 3: Calculate weight: 0.059 × 7850 = 463 kg (1,021 lbs)
Example 2: Steel Bar (20 ft, 25 mm diameter)
Step 1: Convert to meters: 20 ft = 6.096 m, 25 mm = 0.025 m
Step 2: Calculate volume: π × (0.0125)² × 6.096 = 0.003 m³
Step 3: Calculate weight: 0.003 × 7850 = 23.5 kg (52 lbs)

Frequently Asked Questions
How much does a 10×5 foot steel plate weigh at 0.5 inches thick?
A 10×5 foot steel plate at 0.5 inches thick weighs approximately 463 kg (1,021 lbs or 0.51 tons) using standard carbon steel density (7850 kg/m³). Actual weight may vary slightly based on steel type and manufacturing tolerances.
What's the density of steel?
Standard carbon steel has a density of approximately 7850 kg/m³ (0.283 lbs/in³). Stainless steel is about 8000 kg/m³, and aluminum is about 2700 kg/m³. The calculator allows you to adjust density for different materials.
How do I calculate weight for different steel types?
Change the density value in the calculator. For stainless steel, use ~8000 kg/m³. For aluminum, use ~2700 kg/m³. The calculator will automatically recalculate weight based on the new density value.
Is the I-beam calculation accurate?
The calculator uses a simplified rectangular approximation for I-beams. For precise weights, consult manufacturer specifications or use detailed CAD software. The simplified calculation provides estimates within 10-15% of actual weight.
How do I calculate weight for a steel tube?
Enter the length, outer diameter, and wall thickness. The calculator calculates the volume by subtracting the inner volume from the outer volume, then multiplies by density to get weight. This accounts for the hollow center.
Can I use this for shipping weight estimates?
Yes! The calculator provides accurate weight estimates in kilograms, pounds, and tons, which are essential for shipping calculations, freight costs, and crane capacity planning. Always add packaging weight to shipping estimates.
