Angle Profile Cross-Section
Calculation Steps
- Calculate Cross-sectional Area: Area = (Width + Height - Thickness) × Thickness
- Convert Area to m²: Area in m² = Area in mm² ÷ 1,000,000
- Calculate Volume: Volume = Cross-sectional Area × Length
- Calculate Weight: Weight = Volume × Material Density
Weight (kg) = [(Width + Height - Thickness) × Thickness × Length × Density] ÷ 1,000,000

Formula Used
The calculation is based on the fundamental principle of multiplying volume by density to determine weight.
Weight = Cross-sectional Area × Length × Density
Detailed Breakdown:
- Cross-sectional Area: A = (W + H - t) × t
- Volume: V = A × L
- Weight: Weight = V × ρ
Where:
- W = Width of angle profile (mm)
- H = Height of angle profile (mm)
- t = Thickness of angle profile (mm)
- L = Length of angle profile (m)
- ρ = Material density (kg/m³)
- A = Cross-sectional area (mm²)
- V = Volume (m³)
Example Calculation:
For a steel angle profile: 50mm × 50mm × 5mm × 2m
Area = (50 + 50 - 5) × 5 = 475 mm²
Volume = 475 × 10⁻⁶ × 2 = 0.00095 m³
Weight = 0.00095 × 7850 = 7.46 kg

• Weight = 0.0000705 × 8000 = 0.56 kg
Frequently Asked Questions (FAQ)
How do you calculate the weight of an angle profile?
Weight is calculated using the formula: Weight = ((Width + Height - Thickness) × Thickness × Length × Density) / 1,000,000. This accounts for the L-shaped cross-section by calculating the area of both legs minus the overlapping corner.
What is the standard density of steel for angle profiles?
The standard density of structural steel is 7850 kg/m³ (7.85 g/cm³). However, different steel grades may have slightly different densities. High-strength steels might have densities ranging from 7750-7900 kg/m³.
Can I calculate weight for different materials?
Yes, our calculator supports various materials including steel (7850 kg/m³), aluminum (2700 kg/m³), stainless steel (8000 kg/m³), brass (8500 kg/m³), and iron (7200 kg/m³). You can also enter a custom density for specialized materials.
What units should I use for input?
Use millimeters (mm) for width, height, and thickness dimensions, and meters (m) for length. The calculator will automatically handle unit conversions and provide results in kilograms (kg).
How accurate are the calculations?
The calculations are based on standard engineering formulas and are accurate for theoretical weight determination. Actual weights may vary slightly due to manufacturing tolerances, material composition variations, and surface treatments.
What is the difference between equal and unequal angle profiles?
Equal angles have the same width and height (e.g., 50×50mm), while unequal angles have different leg lengths (e.g., 75×50mm). Our calculator handles both types - simply enter the appropriate width and height values.
Can I use this for structural design calculations?
This calculator provides weight calculations only. For structural design, you'll need additional calculations for load capacity, moment of inertia, section modulus, and other structural properties. Always consult structural engineering standards and professionals for design applications.
What safety factors should I consider?
For structural applications, always apply appropriate safety factors as per local building codes and engineering standards. The calculated weight represents the theoretical material weight and doesn't include safety margins for structural capacity.
