5 REVISION. October 2012


The amendment published in IES No. 9, 2016

The amendment was made by the database manufacturer

1 This standard applies to corners of steel bent unequal, manufactured on roll-forming units of cold-rolled and hot-rolled sheets of carbon steel of ordinary quality, high-quality carbon and low-alloyed carbon.

2 The angles are produced by the accuracy of profiling:

A — high accuracy;

B — increased accuracy;

B — the usual accuracy.

3 The cross-section of the non-equilateral angles should correspond to that shown in Figure 1.
