How do you build a sign frame inside a brick monument?

What type of sign are you hanging? ACM, foam, cedar..?

 

It would help to see the sign. It makes a difference how it fits and what it's made of. But fastening to a brick structure is fairly simple.

 

I typically see cabinets mounted with L brackets... thick ones

 

seems like the cart was put before the horse.....

99 out of 100 times this is designed before the structure is built....

sounds like the original sign guy is out?

impossible to suggest what to use when you give 50% of the information needed

 

Lighted??

 

If I understand the frame will be exposed. I would fab an aluminum frame then paint or powdercoat to match or contrast. No rust stains ruining the sign or brick is worth it.

 

The type of sign is going to dictate the frame and mounting method.

example an ACM panel is going to be different than a backlit cabinet.
you also have to take into account the building codes for that location of the sign.

 

Not sure what you keep meaning by "best practices" here...sounds like you have no idea where to even start and are asking how to mount this "best practices" sign.

 

The cheapest method would be to screw some lumber to the brick pillars with masonry screws in anchors, run some lumber stringers across the width, then screw an ACM sign to the stringers that essentially fills the space. It'll be ugly from the back unless you make it two sided.

You can also have a frame welded from square steel tube (or aluminum if you have someone that can do that) which is screwed to the pillars, then attach flat faces to that frame. The frame will typically be built like a ladder.

If you're making a sandblasted foam face or a carved foam face, you'll want to have the foam sign built with a steel strap edge that has mounting flanges, which can then be used to screw to the brick pillars.

Lots of ways to skin this cat.

I've attached a picture of a similar sign installation we did (though it uses faux stone pillars).

 

You can also buy post/panel extrusions to accomplish something like your photo there, as well. We have done a couple between brick pillars like this, all unlit. We used an aluminum cabinet body and ACM panels. Made the outer measurements of the cabinet a couple inches smaller than the opening, then used all-thread and threaded hangers to attach it to the brick and lock nuts inside the cabinet body. Then it was essentially 'floating' and had an equal gap on all 3 sides between the brick. Of course, there are other and I'm sure better ways of doing things.

 

You just answered your own question, drive around and see what you would like to do and if you don't know what you are looking at, take some pictures and ask here. There are different ways of doing them but with out you knowing what your customer wants is difficult to explain how to do it...

 

we build an aluminum frame out of 2x4 or 2x3. then skin it with aluminum. (or whatever substrate you use) i NEVER build a sign for these types of brickwork until the brick is done. We attach the frame from inside with long bolts

 

So, your signs are gonna be about 16" × 48" each...... correct ?? Not being backlit, means you're gonna hafta have some lighting fixtures on the ground. Is a dedicated electric line already run to it ?? If so, talk the people into an electric sign with LEDs and put a topper on it naming the establishment. Have someone you know build it and then lag it into the brick. That is real brick..... correct ?? Work with them and try to get the 6 tenants' signs to do, once they move in. Become the authorized sign guy for the location, so you can assure them, everything will be kosher.

 

One brick at a time. Lol.
