So I have been doing light fabrication for a couple of years and had the opportunity to do a custom sign for a client. Essentially it's a powdercoated steel plate with brass letters on it. I am looking for advice on what is going to be the best way to adhere the brass letters to the sign since I can't weld brass to steel. I would prefer to use an adhesive or epoxy of some sort to maintain the clean look, but safety is a huge concern because I can't risk letters falling off and potentially hitting someone walking under the sign; so brass screws or rivets may be my best option. Hopefully someone can steer me in the right direction or give me some feedback. Thanks everyone!
