Galvanized steel mailbox manufacturers tell you that hot-dip galvanized steel can be divided into hot-dip galvanized steel and hot-dip galvanized steel according to different galvanizing processes. It is to immerse the rust-removed steel parts in a molten zinc solution at about 440~460 ℃, so that the surface of the steel parts is attached with a zinc layer, so as to achieve the purpose of anti-corrosion.

The galvanized steel mailbox manufacturer tells you that the main method of galvanizing the surface of galvanized steel is hot-dip galvanizing. Hot-dip galvanizing is developed from the older hot-dip With the rapid development of cold-rolled strip, the hot-dip galvanizing industry has developed on a large scale.
The manufacturer of galvanized steel mailbox tells you that hot-dip galvanizing is a very good one among various coating methods for protecting steel substrates. The steel is not only plated with a thick layer of pure zinc, but also produces a zinc-iron alloy layer. The manufacturer of galvanized steel mailbox tells you that this plating method not only has the corrosion resistance characteristics of electro-galvanizing, but also has strong corrosion resistance that cannot be compared with electro-galvanizing due to the zinc-iron alloy layer, so this plating method is especially suitable for All kinds of strong acid, alkali mist and other strong corrosive environments.
The manufacturer of galvanized steel mailbox tells you that the application of hot-dip galvanized steel has also expanded with the development of industry and agriculture. Therefore, hot-dip galvanized products are used in buildings (such as: glass curtain walls, power towers, communication grids, water and gas transmission, wire casings, Scaffolding, houses, etc.), bridges, transportation; industry (such as chemical equipment, petroleum processing, marine exploration, metal structures, power transmission, shipbuilding, etc.); agriculture (such as sprinkler irrigation, heating houses), etc. Due to the beautiful appearance and good corrosion resistance of hot-dip galvanized products, their applications are more and more extensive.
