Galvanized (galvanizing) flange is the flange surface covered for zinc for better anti-rust method than light oil coated, galvanizing have hot dip galvanized and cold galvanized two method, hot dipped galvanizing for zinc thickness on flange is much bigger than cold galvanizing, so hot dip Galvanized Flange price is expensive and much higher than cold galvanized for flanges.
