Bob is right -- your best option is a mechanical fastener. You CAN solder galvanized, however, and it works quite well. It is perfectly safe if you're using a soldering iron, which doesn't heat up the zinc enough to be dangerous. You DO NOT want to use a flame to solder it, however, as that will definitely vaporize the zinc coating. This will also make the steel rust much faster, which is undesirable, too.
In any case, even if you're going to use solder, you must have a strong mechanical connection between the parts, or the joint will still be weak enough to break. -vance- Oh and it's the same old story ever since the world began Everybody got the runs for glory nobody stop and scrutinize the plan. --Paul Simon
