Sorry! That was a typo. Should have been:

Span Loading not more than 0.62 psf



I'm still not quite clear...

How does the span loading come out in pounds per square foot?

It is calculated as weight divided by the square of the span.
Which, if other posters are correct, is not the normal way to
calculate it.
