Galvanized Steel flanges are steel flanges that, after being manufactured, will be hot-dip galvanized. In order to improve the service life of the flange and its resistance to oxidation.
On the market, the price of hot dip flanges is much cheaper than stainless steel flanges. That’s a big advantage of it.
