When S ≤ 6 mm, R=1.5S, the recommended calculation formula for the theoretical weight of rectangular steel pipes is shown in equation (A.3);

When S>6 mm, R=2S, the recommended formula for calculating the theoretical weight of rectangular steel pipes is shown in equation (A.4).
G=0.015 7S (A+B -2 858 4S) (A.3)
G=0.015 7S (A+B -3 287 6S) (A.4)
In the equation:
G -------- Theoretical weight of rectangular steel pipe (density of steel is calculated as 7 85 kg/dm3), in kilograms per meter (kg/m);
A. B ------- The length and width of rectangular steel pipes, in millimeters (mm);
S -------- The nominal wall thickness of rectangular steel pipes, in millimeters (mm)
