Locking a metal gate with a deadbolt

deadboltgatesmetalSecuritywelding

I'm having a metal fence custom-made that will have a regular (pedestrian) gate as well as a double gate for vehicles. I'd like to install deadbolts on both gates for better security than other locking methods.

I see several places sell metal boxes that can be welded on with two holes (for a deadbolt and lever) or one hole (for just a deadbolt), so it seems like that will work well. But I'm wondering what to do on the other side opposite the deadbolt. I could just drill a hole through the post, but then there's no strike plate. Or weld a strike plate on and leave a bigger gap to accommodate it? Or do they sell similar metal boxes to weld into the other side?

A deadbolt doesn't need a strike plate, because the gate is swung with the bolt retracted, and then using the key the bolt is advanced into the hole.

You can use the strike plate if you want and screw or weld it in position over the hole.

For the double gate consider organising the ground pin so that it interferes with the deadlock pin or the other leaf of the gate so that it can't be withdrawn until the gate is unlocked
