あらすじ・解説
Galvanized steel flanges are steel flanges that have been coated with a thin layer of zinc. They are made by dipping carbon steel flanges into a molten zinc bath. It creates a thin coating of zinc on the surface of the flange, which protects the flange from rust and corrosion, even in harsh environments. The thickness of the zinc coating typically ranges from 0.002 to 0.005 inches.
