Double Angle · AISC Shapes Database v15.0 · United States
2L6X6X3/4 is a double angle 152 mm deep × 152 mm wide, 19.1 mm thick, weighing 85.4 kg/m. The dimensions below are the published AISC Shapes Database v15.0 values; the drawing is generated from them.
Double angles pair two matching angles back to back — the classic bolted truss chord and web member, tabulated for the pair acting together.

Derived section properties
Integrated from a square-cornered outline — the fillet radii this family really has are not drawn, so the computed values differ slightly from published. For 2L6X6X3/4 the computed area is 0.15% from published and Ix 0.20%. Where a value is also published, the published one above is the one to quote.
| Property | Value |
|---|---|
| Elastic modulus, Sx | 218,403 mm³ |
| Elastic modulus, Sy | 299,000 mm³ |
| Plastic modulus, Zx | 393,626 mm³ |
| Plastic modulus, Zy | 490,844 mm³ |
| Radius of gyration, rx | 46.4 mm |
| Radius of gyration, ry | 64.7 mm |
S is the elastic modulus and Z the plastic modulus, following AISC 360. Australian and British practice reverse the letters.
