How to Use
Step 1: Enter Dimensions
Input the length of your angle bar in meters and the width of both flanges in millimeters. For equal angle bars, both widths will be the same.
Step 2: Specify Thickness
Enter the thickness of the angle bar in millimeters. This is the thickness of the steel plates forming the angle.
Step 3: Select Material
Choose from common materials like steel, aluminum, or stainless steel. For other materials, select "Custom Density" and enter the specific density.
Step 4: Calculate
Click the "Calculate Weight" button to get instant results including total weight, volume, and material specifications.
Formula Used
Basic Formula:
Weight = Volume × Density
Volume Calculation:
Volume = [(Width1 + Width2) × Thickness - Thickness²] × Length
Where:
- Width1, Width2 = Width of angle flanges (mm)
- Thickness = Thickness of the angle bar (mm)
- Length = Length of the angle bar (m)
- Density = Material density (kg/m³)
Common Material Densities:
- Steel: 7850 kg/m³
- Aluminum: 2700 kg/m³
- Stainless Steel: 8000 kg/m³

Examples
Example 1: Equal Angle Bar
Dimensions: 50mm × 50mm × 5mm, Length: 6m
Material: Steel (7850 kg/m³)
Calculation:
Volume = [(50 + 50) × 5 - 5²] × 6000 = [500 - 25] × 6000 = 2,850,000 mm³ = 0.00285 m³
Weight = 0.00285 × 7850 = 22.37 kg
Example 2: Unequal Angle Bar
Dimensions: 75mm × 50mm × 8mm, Length: 3m
Material: Aluminum (2700 kg/m³)
Calculation:
Volume = [(75 + 50) × 8 - 8²] × 3000 = [1000 - 64] × 3000 = 2,808,000 mm³ = 0.002808 m³
Weight = 0.002808 × 2700 = 7.58 kg
Frequently Asked Questions
An angle bar, also known as angle iron or L-bracket, is a structural steel member with an L-shaped cross-section. It consists of two perpendicular flanges and is commonly used in construction and engineering for providing structural support and reinforcement.
Our calculator uses standard engineering formulas and provides highly accurate results. However, actual weights may vary slightly due to manufacturing tolerances, material composition variations, and surface treatments.
Yes! The calculator supports steel, aluminum, stainless steel, and custom materials. Simply select "Custom Density" and enter the specific density of your material in kg/m³.
Equal angle bars have both flanges of the same width (e.g., 50×50mm), while unequal angle bars have different flange widths (e.g., 75×50mm). Both types can be calculated using this tool by entering the respective widths.
Weight calculations are crucial for structural design, load-bearing capacity analysis, material cost estimation, transportation planning, and ensuring safety standards in construction projects.
