H Beam Weight Calculation Formula

The theoretical weight of an H beam is calculated considering the fillet radius (r) at the junction of web and flange:

Standard Formula (with Fillet Radius)

Weight per meter (kg/m) = ρ × A

Where:

  • ρ = Density of steel = 7.85 g/cm³ = 7850 kg/m³
  • A = Cross-sectional area (cm²)

Cross-Sectional Area Calculation

A = 2 × B × tf + (H - 2 × tf) × tw - (4 - π) × r²

Where:

  • H = Overall height (mm)
  • B = Flange width (mm)
  • tw = Web thickness (mm)
  • tf = Flange thickness (mm)
  • r = Fillet radius (mm)

Simplified Formula (Ignoring Radius)

For quick estimation (±2% accuracy):

Weight (kg/m) ≈ 0.00785 × [2 × B × tf + (H - 2 × tf) × tw]

Total Weight Calculation

Total Weight (kg) = Weight per meter × Length (m)

Important Notes
The fillet radius (r) reduces the cross-sectional area by approximately (4 - π) × r² ≈ 0.858 × r² for four corners. This correction typically reduces the calculated weight by 1-3%. Always use the exact fillet radius value provided in the standard for precise calculations. Actual delivered weight may vary due to manufacturing tolerances (typically ±4-6%).

Standard Tolerances

Dimensional tolerances for H beams per international standards.

GB/T 11263 (China)

  • Height (H): ±3.0 mm for H ≤ 300 mm; ±4.0 mm for H > 300 mm
  • Width (B): ±3.0 mm for B ≤ 200 mm; ±4.0 mm for B > 200 mm
  • Web thickness (tw): +1.0 / -0.5 mm
  • Flange thickness (tf): +1.5 / -0.5 mm
  • Weight tolerance: ±6% for individual piece; ±4% for batch

ASTM A6 (USA)

  • Depth and flange width: ±5 mm for sections ≤ 600 mm
  • Web thickness: ±0.75 mm
  • Flange thickness: ±1.5 mm
  • Weight tolerance: ±2.5% for theoretical weight over 20 kg/m

EN 10034 (Europe)

  • Height (H): ±3 mm for H ≤ 400 mm; ±5 mm for H > 400 mm
  • Width (B): ±4 mm
  • Thickness (tw, tf): ±0.5 mm for t ≤ 10 mm; ±1.0 mm for t > 10 mm
  • Mass per meter: ±4.5%

Frequently Asked Questions

How accurate is the H beam weight chart?
The chart provides theoretical weights based on nominal dimensions and standard steel density (7.85 g/cm³). Actual weights may vary by ±4-6% due to manufacturing tolerances, fillet radius variations, and steel chemistry. For procurement, use mill test certificates for exact weights.
What is the difference between H beam, I beam, and W beam?
H beams (wide flange beams or W-shapes in the US) have flanges of equal or nearly equal width to the web height, making them efficient for columns. I beams have narrower flanges and are efficient for bending applications. Modern usage often treats "H beam" and "W beam" as equivalent.
Why include the fillet radius (r) in weight calculations?
The fillet radius is the curved transition between web and flange created during rolling. It reduces the cross-sectional area by approximately (4 - π) × r² ≈ 0.858 × r² for four corners. Ignoring it can overestimate weight by 1-3%, which matters for large quantities and tight budgets.
How do I convert between GB, ASTM, EN, and JIS standards?
Direct conversions are not exact because each standard has unique size ranges and tolerance rules. Cross-reference by matching height, width, web thickness, flange thickness, and section modulus. Always verify strength requirements (yield/ultimate) when substituting grades between standards.
What is the typical weight tolerance for H beams?
Typical weight tolerances are ±4-6% for individual pieces and ±4% for batches, depending on the standard and mill practice. ASTM A6 allows ±2.5% for theoretical weight over 20 kg/m, while GB/T 11263 allows ±6% for individual pieces and ±4% for batches.
How much does a 6-meter H beam weigh?
It depends on the size. Example: H-200×200 (50.5 kg/m) × 6 m = 303 kg; H-300×300 (94.5 kg/m) × 6 m = 567 kg; W12×50 (74.4 kg/m) × 6 m = 446 kg. Use the calculator above for your exact dimensions.
What steel grades are used for H beams?
Common grades include Q235B/Q345B (China), ASTM A36/A572/A992 (USA), S235/S275/S355 (Europe), and SS400/SM490 (Japan). For structural construction, A992 and Q345B/S355 are widely used due to their high strength and weldability.
