Note. The cross-sectional area and weight of 1 m of the rod is calculated based on nominal size, the density of steel is equal to 7.85 g/cmГОСТ 1133-71 Сталь кованая круглая и квадратная. Сортамент.


Examples of symbols are:

round stamps U10 with a diameter of 40 mm:

ГОСТ 1133-71 Сталь кованая круглая и квадратная. Сортамент


square stamp U12 with a side of a square 60 mm:

ГОСТ 1133-71 Сталь кованая круглая и квадратная. Сортамент

3. Ovality (difference between the largest and smallest diameters in the same cross section) round steel and Combichrist (difference between the diagonals in one cross-section), square steel should not exceed 0.6 tolerances for diameter or side of square.

4. Diameter and ovality of round steel, the side and diagonal of a square of steel measured at a distance of not less than 100 mm from the end.

5. The bars are supplied in lengths of not less than:

1.5 m — diameter round or square up to 50 mm;

1.0 m — diameter circle or square over 50 to 75 mm;

0.75 m — diameter circle or square of St… 75 mm.

Delivery of bars with a length of at least 0.5 m in an amount of not more than 10% of the batch weight.

By agreement of the parties, the bars can be supplied in length not less than 0.5 m.

6. Limit deviations of the length bars in lengths and dimensional length, must not exceed:

+70 mm, for bars with diameter or side of square from 40 to 80 mm;

+100 mm for bars with diameter or side of square over 80 to 150 mm;

+150 mm for bars with diameter or side of square in excess of 150 mm.

7. Square steel comes with sharp edges. It is possible to supply square steel with blunt edges; dullness should not exceed 0.15 of the square.

8. The curvature of the rod should not exceed 0.5% of the length.

9. The apparent twisting square steel around the longitudinal axis is not allowed.

10. Steel grades and specifications are established by the relevant standards.
