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

I haven't used pads under shelving but I have under other things. They can
be difficult to keep in place while setting up unless they are bolted or
welded to the legs. A bigger problem is twisting since the diagonal braces
typically resist only tension.

Hey thanks Jim, I've already planned on using some angle scraps to
fasten the uprights to the base pads.

Look at grocery store shelving. Usually called gondola shelving.
Cantilever strength depends on THE strength of the materials.

Are you confusing mud with concrete?

Not sure how many tons you plan to put on this shelf to cause the legs to
punch through through your concrete floor. Securing it to a wall so it
doesn't twist and fall over is not a bad idea though. Single shelving
units are fairly unstable, unless it's something like a Metrorack.
