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.

Legend to Figure 1 and Tables 1 and 2

 — the width of the larger shelf;

 — the width of the smaller shelf;

 — thickness of the shelf;

 — radius of curvature;

 — moment of inertia;

 — radius of inertia;

,  — the distance from the center of gravity to the outer surfaces of the shelves;

 — cross-sectional area;

 — the ratio of the estimated overhang of the greater shelf to the thickness of the profile;

 — the ratio of the calculated overhang of the smaller shelf to the thickness of the profile.

4 Dimensions, cross-sectional area, reference values for axes and mass of 1 m corners shall correspond to:

for corners of carbonaceous boiling and semi-quartz steel of ordinary quality, carbon quality steel with a time resistance of breaking no more than 460 N / mm (47 kgf / mm ) — given in Table 1;

for corners from carbon semi-quiet and calm steel of ordinary quality, carbon quality steel with a temporary rupture resistance of more than 460 N / mm (47 kgf / mm ) and low-alloyed — given in Table 2.
