What are CISC Double Angles?

Browse CISC Double angles from Structural Section Tables SST12.1. Compare metric-native dimensions and section properties, open a designation for full details, or load a section into Optimal Beam.

Designations

Understanding Double Angles designations

Double-angle designations begin with 2LE, 2LL or 2LS for equal-leg, long-leg or short-leg back-to-back orientation, followed by metric leg sizes and thickness. Because the name does not select a gap, this finder displays the published Ry0 contact configuration by default; the Section Builder also offers 8, 10, 12, 16 and 20 mm gaps.
