I picked up a sturdy shelving unit (2' x 4' for now) from a local industrial liquidator; it uses perforated angle for the uprights, and will live in a residential garage.
While the unit is far more sturdy than I will load it, I still can't help but think about all of the weight being concentrated on four 1-1/2" angle ends on the concrete pad.
Is it typical to put some type of base below the angle ends to spread the load out (steel/wood)?
Thanks,
Jon
