Bollard's

I will typically see a minimum requirement of 3” sch 40 steel. Min bury of 36” and min height of 36”. 6 foot total length.

I have seen 3” sch 40 steel, 4” sch 40 steel, 6” OD 10 GA, 6” .250 steel. Most the 6” bollards I have seen have been filled with concrete, with a domed finish on the concrete. The 3” & 4” bollards typically have a steel end cap welded on the top.

Oh, and painted yellow, so they leave a nice paint mark on car bumpers.:):)

How about bollards with a baseplate with 4 red head bolts? Does it necessarily have to be in concrete?

The bolts with a base would probably work in cement, but not asphalt. If some body hits the bolted down bollard with a vehicle, it will pull the bolts out, and probable not bend the bollard.

should still leave a nice yellow paint mark on the vehicle though.:)

I have also fabricated removable bollards. I’ve set 36” of 1/4” wall steel flush with the ground. Then I’ve taken 24” of 5” sch 40 steel and welded it inside the one end of the 6”, with 12” sticking out. Cap the end of the 5” and fill the above ground 6” with cement. It will be removable with equipment, but too heavy for miscreants to pull out of the socket by hand.
 
I have used a 4" metal fence post, bury about 24" and fill with concrete, plus some concrete at the base. Graingers makes a slip over PVC sleeve, looks nice when done.
The above I have done by myself.
Sometimes if we have a backhoe out, we dig a hole and put in concrete guard posts, precast with rebar inside, about 8" dia, 6 ft long, lift with backhoe, but no concrete req.

Your post with anchors would not hold up to a bumper and car, too much leverage and weight.
 
We do a lot of parking lot lighting and end up with a slew of damaged or scrapped steel poles. We saw them to length and place them where conditions require.

Doesn't do much protecting of whatever the bollard was put in for as those red heads would pull out easy with all the leverage that would be working against them, unless maybe the base plate were maybe 10 foot square or larger

At 10' square, the vehicle tire would almost certainly be resting on the upstream side of the base plate, rendering the leverage of the hold-down bolts moot.
