What is an ISA Angle?

ISA stands for "Indian Standard Angle" - a standardized steel angle section used in construction. These angles are manufactured according to IS 2062 specifications and are available in both equal and unequal leg configurations.

Key Components of Angle Weight Charts

  • Dimensions: Leg lengths (A × B) in millimeters or inches
  • Thickness: Wall thickness of the angle section
  • Weight per Meter: Mass per unit length (kg/m or lb/ft)
  • Cross-sectional Area: Total area of the angle profile
  • Moment of Inertia: Resistance to bending (for structural calculations)

Equal Angle Weight Chart

Equal angles (L-sections) have legs of equal length and are the most commonly used structural angles. They provide balanced strength in both directions and are ideal for bracing, framing, and general construction applications.

Weight Calculation Methods

Understanding how to calculate steel angle weights is crucial for accurate material estimation and structural analysis. Here are the primary methods used for angle weight calculations.

Formula-Based Calculation

Basic Weight Formula:

Weight (kg/m) = Cross-sectional Area (cm²) × 0.00785 × Length (m)

Where 0.00785 is the density of steel in kg/cm³

For Equal Angles:

Cross-sectional Area = 2 × (Leg Length × Thickness) - (Thickness)²

For Unequal Angles:

Cross-sectional Area = (Leg A × Thickness) + (Leg B × Thickness) - (Thickness)²

Important Note:

These formulas provide theoretical weights. Actual weights may vary slightly due to manufacturing tolerances, material composition, and surface treatments. Always refer to manufacturer specifications for precise values.

Frequently Asked Questions

What is an angle weight chart?

An angle weight chart is a reference table that provides the weight per unit length for different sizes of steel angles. It includes dimensions like leg length, thickness, and corresponding weights, making it essential for structural calculations, material estimation, and cost analysis in construction and engineering projects.

How do I calculate the weight of steel angles?

Steel angle weight can be calculated using the formula: Weight = Cross-sectional Area × Length × Density of Steel (7850 kg/m³). For equal angles: Area = 2 × (Leg Length × Thickness) - (Thickness)². Alternatively, you can use our angle weight calculator or reference the weight chart for quick calculations.

What is the difference between equal and unequal angles?

Equal angles have legs of the same length (e.g., 50×50mm), providing balanced strength in both directions. Unequal angles have legs of different lengths (e.g., 100×75mm), offering asymmetric strength characteristics. Equal angles are used for general bracing and framing, while unequal angles are preferred for specialized applications where different load capacities are needed in each direction.

What does ISA stand for in steel angles?

ISA stands for "Indian Standard Angle" - a standardized steel angle section manufactured according to IS 2062 specifications. ISA angles are widely used in Indian construction and are available in both equal and unequal leg configurations. The designation includes dimensions and thickness (e.g., ISA 50×50×6 means 50mm legs with 6mm thickness).

How accurate are the weights in the chart?

The weights in our chart are theoretical values calculated based on standard steel density (7850 kg/m³) and nominal dimensions. Actual weights may vary by ±3-5% due to manufacturing tolerances, material composition variations, and surface treatments. For critical applications, always verify weights with manufacturer specifications or physical measurements.

Can I use this chart for aluminum angles?

No, this chart is specifically for steel angles. Aluminum has a different density (2700 kg/m³ vs 7850 kg/m³ for steel), so aluminum angles will be approximately 65% lighter than steel angles of the same dimensions. Use our aluminum weight calculator for accurate aluminum angle weights.

What are the most commonly used angle sizes?

The most commonly used steel angle sizes include: 40×40×5, 50×50×6, 60×60×6, 75×75×6, and 100×100×10 for equal angles. For unequal angles, popular sizes are 65×50×6, 75×50×6, 100×75×8, and 125×75×10. The choice depends on the specific application, load requirements, and structural design considerations.

How do I select the right angle size for my project?

Selecting the right angle size depends on several factors: load requirements, span length, connection methods, and local building codes. For structural applications, consult a qualified engineer. For non-critical applications, consider factors like weight capacity needed, available space, and cost. Our construction calculators can help with basic sizing decisions.
