sure, but I'm not interested in whether something will go through a tile.
actually, these ratings always puzzle me a bit - given that a rack will
always have wheels on four separate tiles, is a 1250 rating assuming the 
rack is ~4000 lbs?  oh, maybe if you have a rack on diagonal and/or very 
badly balanced?

good advice.  unfortunately, vendors tend to give numbers so safety-padded
that they're unrealistic.  for instance, designing machinerooms based on 
the peak theoretical load of a computer's PS - say 500W for a dual-opteron
which I can measure consuming <250W under load...
