Section properties
The structural properties of L 20 x 20 x 3 are available in the Steel Profiles app with the European library:
- Iy, Iz, Wel, Wpl, i
- Iu, Iv, iu, iv and Iyz (principal axes)
- IT
- Bolt sizes, edge distances and net areas
- EN 1993-1-1 compression class
The app also runs design checks to EN 1993-1-1 on L 20 x 20 x 3, finds the closest sections in the AISC, British, Canadian and Australian standards and compares it side by side with any other section.
