Since these are in no particular order, here’s the address marker I made for the house. We’re in a small gated community of 45 homes on ~acre lots; most of the neighbors have their addresses on boulders or flagstone. I’m more of a metal guy, so I decided to integrate both.
The previous owner had a nice thick piece of flagstone and some ceramic tile numbers she was going to use for her address marker. I liked the flagstone, so I kept it and sent the tiles to a local thrift shop.
Wanted something that reflected the mining heritage of the Superstition Mountains and incorporate the rusted iron design elements we already had going on the property.
Had a bunch of 3/8” rebar and 1x1 tubing left over from the trellises I built for the courtyard and golf course so I used that. First step was to build a rebar cage for the Palo Verde stone we already had in the landscape drainage.

After the cage was complete I scrounged up enough sheet metal to built the bulwarks. Outside wall were cut from 16 gage steel purlin stock, the inside walls were cut out of a couple of old 2’ recessed light troffers. (did mention I am a bit of a scrounger, didn’t I?)The tops were new 20 gauge that were just hand bent and tacked into place. After A couple of hundred tack welds the corners were ground smooth and blended.

Next step was to hit all the flats with a flap wheel to remove all the paint and prepare for the patina.
Best way I have found to put an instant rust patina on steel is to spray it with a mixture of vinegar, salt, and hydrogen peroxide. It will foam up as it works, don’t try to wipe it off- just let it go, it will disappear as it ages.

Formed and poured a little pad to bolt this to. Used it as an opportunity to get rid of more pieces of scrap rebar, etc.-tacked together a little reinforcing cage, then poured three bags of ready mix. Added a bottle of buff concrete color let the slab blend into the landscape gravel.

Ready to install the marker, just put in a couple of Tapcons to keep in in place, then filled the rebar cage with 4”+ Palo Verde stone. Top bolts on with four 1/4” bolts, nuts were welded into the frame and ground flush during fabrication.

I actually tried to copper plate the steel numbers with copper sulfate using instructions I found online but it didn’t really work. I wanted them to weather out naturally to a copper verdigris finish, but that might be a project for a later date. The numbers were bandsawed out of 3/16” plate with 1/4” bolts welded to the back as stand offs. They’re just friction fit into 1/4” holes in the flagstone so I can just pop them out and get them plated if I decide to go that route.
