a homeowner has inquired about having heavy duty metal braces to support a granite countertop(with a brushed nickel finish). the mz of granite ct is 1″thick x 18″in. deep x 6’ft. long. the approx. weight is 130lbs.
My questions are:
– would 2 braces with approx weight bearing of 100lbs a pc.
2 metal triangular brackets placed/installed under ct, fastened to framing backer or stud & epoxied to underside of CT be sufficient?
– is epoxy recommended for bond b/w granite & metal support bracket?
– can anyone recommend an internet website company that offers heavy duty metal brackets (triangular), or would you recommend stopping at a local fabricating shop?
I am a carpenter, & truly a novice with the medium of metal.
thank you!

Greetings Chipper,
This post, in response to your question, will bump the thread through the 'recent discussion' listing again.
Perhaps it will catch someones attention that can help you with advice.
Cheers

Talk to the supplier of the granite about how it needs to be supported. It may need more than just two brackets, it may need continuous support under the front edge. It's typical to have a local fabricator make stuff like that. Either take them a detailed drawing or have them come out and measure.
Double stick tape or liquid nails would work for fixing the bracket to the underside of the granite. Once the weight gets on the backet, it not gonna move much. Be sure to screw it to a stud.

the finish wall surface underneath the granite bar countertop is 5/8"in thick drywall.
question - lag bolting (2) fabricated metal support brackets on the underside of the CT 48"o.c., lag bolted into the stud (with drywall wall finish) would the downward exertion of the heavy countertop bear weight on the bottom backplate of bracket, bracket which is lagged into stud, & dig into drywall? or does the wt. bear on the lag screw?
if the wt. is carried on the lag screw , maybe nothing to worry about?
if it will bear on the bracket, & there is a chance of inward movement of bracket into drywall finish??????????????????
would you recommend stopping at a local fabricating shop?
I'd go local, if only since you can "shop" that way better for custom, one-off, items like this.
I'd look in the yellow pages under Metal Fabrication. First question I'd ask is "Do you, or have you, worked with brushed nickel metalwork before?" If there's more than one place, I'd keep asking until I got a "yes." "Brushed nickel" is not something we can typically send out to the powder coaters or the like (not for a close-up, reach out and touch, indoors item like this will be). It might be a finish you could get fabricated aluminum anodized in, except for adding in the complication of aluminum fab . . .
Now, most metal shops seem to be very good at translating scrawls on napkins & the like, but they really appreciate drawn-out details. So, it can be worth investing some time in a decent sketch to start. If only to make a starting point where they can go, hey, we have x on hand, and it'd do what you want . . .
