Summary for bronze plating of steel Discussion
Bronze plating of steel for large table parts is discussed, but the key advice is that the bronze look is usually not made by true bronze electroplating. In the answer, A. says bronze electroplating is possible and sometimes used for engineering work, but the finish Chris wants is more commonly achieved by copper electroplating, then darkening the surface and sealing it with a protective clear coat. That means Chris’s prior experience with copper plating and liver of sulfur-like coloring is still relevant, even though the parts are too large for the tanks he has found in Minnesota. The thread does not offer a specific shop or tank solution, but it does point him toward the more practical finishing route for an aged bronze appearance on steel.
I’m looking to get an aged bronze finish on some 1/2″ thick brushed steel parts. The problem is the parts are larger than any tanks I can find in Minnesota. The parts are 30.5″ x 20.125″, 26.5″ x 20.125″, 43″ x 10.125″…
I’ve done things this size in copper having them plated and using liver of fish oil but never bronze.
The parts are for a table I’m making.
Any Ideas, suggestions, amusing anecdotes would be most appreciated, thanks
Chris

A. Hi Chris,
Although it is possible to do bronze electroplating, and it is occasionally done for engineering purposes, the bronze look you are visualizing is probably rarely if ever done by actual bronze electroplating; rather, it’s done by copper electroplating followed by a darkening treatment and then a protective clear coat.
So if you’ve done copper plating of these before, you’re still on the right track.
Luck & Regards,
