Different applications of galvanized iron

Galvanized iron is a kind of iron ore which has been refined, molded as well as coated with zinc plating. As you know, zinc coating can resist corrosion and rusting and provides the galvanization as well. Cast iron and welded steel pipe need galvanizing in the construction industry, for these products are widely used for external environment. There is a great variety of purposes for the application of galvanized ore. However, you may be stunned at the primary use of galvanized iron which is employed to sheet metal roofing and other building materials including metal roof shingles and fencing. Of course , steel pipes, wire mesh and other exterior architectural products are also in a great demand for galvanized iron. Do you know the history of the ‘galvanize’?

In the 18^th century, a Italian physician and physicist found galvanizing who had the experience in the field of bioelectricity and electrochemistry. Then the term galvanized appeared from Luigi Galvani. His researches concentrated on chemical areas and also included electric reactions without leading to galvanized iron directly. The chemical reactions between metals and zinc-covered products such as zinc coated iron can also inspire his interest, which have contributed to the development of modern galvanized iron industry. On the basis of his experiments, now people can manufacture quantities of steel pipe product for modern construction like pre galvanized steel pipe. Construction materials with zinc coating can be used under atrocious circumstances. Are you interested in the process of the galvanizing?

As we all know that the process of galvanizing is complex with several different processes. The most well-informed is electro-galvanization. At first, the molded iron is immersed in the zinc sulfate solution. Hot dipped galvanized steel pipe is produced by this process. Another common process is iron dipped into molten zinc or zinc alloys. Besides, iron can be dusted with powdered zinc particles. Painting and spraying molten zinc onto the metal are also kinds of galvanizing process.

Different applications require different types of iron galvanization. For example, hot-dipped or electroplated methods are widely used for the products exposed to the bad conditions. For inferior products, painted or sprayed measure is suitable for the requirements. However, galvanized iron is not completely corrosion-resistant. Steel pipe supplier should make clear about the application knowledge of galvanized iron in ways that help contractor to use it correctly. For example, acid rain and tannic acids from certain trees are detrimental to steel pipes, which will cause irreparable damages to construction.
