Table 1 — Dimensions and sectional properties of hot-rolled equal-leg angles (concluded)

NOTES

1. Member countries may choose, to be included in their national standards, the sizes which are required to meet their demand.
2. For the angles so chosen, only thicknesses which can be rolled in their mills to meet the demand of the users may be selected from the list of thicknesses corresponding to equal angles in table 1.
3. The sectional area has been calculated using the formula

   S = [l/2 A - l) + 0,214 6 (r_root² - 2r_toe²)] × 1/100

   where
   

   S is the sectional area, in square centimetres;
   

   l is the thickness, in millimetres;
   

   r_root is the root radius, in millimetres;
   

   r_toe is the toe radius, in millimetres;
   

   A is the leg length, in millimetres.

4. Mass is calculated on the basis of density of steel of 7,85 kg/dm³.
