13' custom metal gate and post support

[roadrunner255]

Hello all,
I am having 6' game fencing installed and have a question about a gate post support question.
Qate post will be close to property line and custom gate will be 1.25" square tubing about 150lbs 5' height.
Whats that gate post support suggestions?
Post dia, metal, supports, lenght?

Thanks

Btw, i am in central, no hard freeze and lots of limestone.

I would be putting in something like 6x6x.25 HSS at least 4' deep and probably about an 18" diameter hole. This assumes a single panel 13' wide completely cantilevered from the single post. If you want round 8in Sch 40 pipe would work too.

This is probably a bit of overkill but it also isn't going to sag over time.

Probably underestimating the gate weight by 25% or more. A 16’ cheapie stock gate is close to 100 lbs and is made out of 18 ga. tubing. Unless you are putting a wheel at the tip, it will need a tension wire to adjust for the sag.

To start is this a swing gate or roller?

Wing gate, from corner of the building 13' out to the property line.

Gate hinge post on the property side.

Why would you put the hinge side on the property line when you already have a rock solid hinge post on the other side..The building.

125lbs 13' out is quite a bit of leverage. Your going to want a deep and wide hole for concrete

Metal building, maybe I should use 2 6' gates instead.

I would consider a sliding gate.

Your desire is achievable, but the detail it takes to succeed long term without sagging over and dragging is more than I intend to type on an iPad. I would suggest getting a structural steel company involved and possibly an engineer. It can be done with the simple appearance of being a basic gate, but that's because there is going to be a lot of structure and concrete under grade. This isn't a simple matter of sticking a 4x4 square tube into a hole with a few bags of sackrete.

I made two different metal gates made of 1 1/2" square tube and rebar. One has two 10' gates and the other has two 8' gates. Both are supported by 4" drill pipe that stand 12' tall above ground with 3" drill pipe as a dog leg to add support and aid in frost heaving in my crappy soil. The holes are 6' deep and roughly 18" diameter. I also added some stubs to the pipe to aid in anchoring the pipe to the concrete.
Two years of freezing and thawing and no movement.

I did two eight foot gates. Poured 1200 pounds of concrete in each hole. Put four of biggest j bolts I could get for the post and another two a foot behind the post for a guy if I needed it. Welded plate to bottom of 4x4 steel with holes for the j bolts. This was first Line of making level. Also used adjustable welded hinges. Was no problem. Year later no sag.
However cause it’s such a pain to get in and out I’m changing to a sliding gate I can use an opener with.

Thanks all, looks like I'll be going with a gate from tsc only 60lbs.

I would put a wheel under the outer end. You could build up a spot to rest the wheel on when it's closed and another spot for when it's open. No need to have a support through the swing area since it isn't there very long. I little bit of a ramp as it approaches each spot would be nice.
