There's that.  I find particle board and OSB untrustworthy.
As Fred suspected, the rivet-lock ones with particle-board shelves
do tend to change over time.  In a decade in a basement even with a
dehumidifier, heavy objects easily distort the shelves.  They may
be fine for light-duty.  

I've tried some of the plastic ones, too, 2" thick shelves with corrugation 
and struts that would give the impression of strength - but over time, even 
with objects only as heavy as monitors and computers, they've sagged an 
inch in the middle of a yard-wide span.
