All
weights are theoretical. They are computed on the basis of the
specific gravities of the metals involved.The
weights shown would be accurate if steel could always be produced
to exact size. This is seldom possible in commercial practice.
Accuracy of dimensions, particularly of hot rolled steel products,
is influenced by many factors, such as mill design, heating
practice, reduction between passes, roll wear, roll pressure,
composition of steel and standard tolerances. |
