Unequal Angle Bar Weight Calculator

Here’s a comprehensive table summarizing key information about unequal angle bar weights:

Aspect	Details
Definition	Angle bar with legs of different lengths
Common Materials	Steel, Aluminum, Stainless Steel
Density (approx.)	Steel: 7850 kg/m³, Aluminum: 2700 kg/m³, Stainless Steel: 8000 kg/m³
Weight Formula	Weight = [(L1 + L2 – T) × T] × Length × Density
Variables	L1 = length of first leg, L2 = length of second leg, T = thickness, Length = bar length
Typical Sizes	Leg lengths from 20mm to 200mm (can vary by manufacturer)
Common Thicknesses	3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm
Standard Lengths	6m, 9m, 12m (20ft, 30ft, 40ft)
Size Designation	Usually expressed as “larger leg × smaller leg × thickness” (e.g., 75×50×6mm)
Tolerances	Typically ±1mm on leg length, ±0.5mm on thickness (may vary by standard)
Standards	EN 10056, ASTM A36 (steel), AA 6063 (aluminum)
Finishes	Hot-rolled, cold-formed, galvanized (for steel); mill finish, anodized (for aluminum)
Applications	Structural support, framing, bracing, general fabrication
Advantages	Versatility, strength-to-weight ratio, ease of fabrication
Calculation Tools	Online calculators, engineering software
Factors Affecting Weight	Material density, leg lengths, thickness, overall length
Corrosion Resistance	Depends on material (stainless steel and aluminum generally better than carbon steel)
Weldability	Good for steel and aluminum (with proper techniques)
Heat Treatment	Possible for some materials to alter properties
Cost Factors	Material type, size, finish, market conditions

Remember that actual weights may vary slightly due to manufacturing tolerances and specific alloy compositions. Always consult manufacturer specifications for precise weights when critical. The unequal leg design offers flexibility in engineering applications where different leg lengths are beneficial for specific structural or aesthetic requirements.
