Hot Dip Galvanizing – An overview

The word ‘galvanizing’ refers broadly to the electro-deposition procedure where any thin layer of any other material is inserted to any item that is made of steel. The core reason of the galvanizing process is to guard the base steel by avoiding the rusting. Though, one of the best galvanizing processes invented by the galvanizer companies does not utilize any kind of electrochemical deposition. This process is known as HDG or hot dip galvanizing.

This type of galvanizers has widely become very popular due to the effectiveness it offers while it comes to the corrosion protection. Actually, in the recent terms, the word ‘galvanizing’ or ‘galvanizers’ is popularly used to mention the process of hot dip galvanizing. In this process, a corrosion resistant four-layer surface or finish is produced on the steel base by using the zinc through the electrochemical procedure. As per the galvanizer consultant companies, commonly iron and steel are passed through any molten bath made of zinc at the temperature of 460˚C in order to protect the metals from corrosion. Among the four layers made up by the hot dip galvanizing consultant companies, the top layer is made of zinc and the underneath three layers are created of zinc-iron alloy. The galvanizer companies use this procedure for all the industrial applications which need the potency of steel while maintaining the resistance to the corrosion.

The method of hot dip galvanizing created by the hot dip galvanizing consultant companies has proved to be much more superior than the other methods like metalizing, paint, electroplate galvanizing or mechanical galvanizing. Besides, this method of galvanizing has come out as one of the most reliable as well as result oriented procedures which meets with all the galvanizing requirements of the clients. Unlike the electroplate method of galvanizing, the process of hot dip galvanizing creates a much durable and thicker coating that makes it very suitable also for the outdoor applications. On another side, the thin coating made by the electroplate galvanizers can be consumed quickly and it results in revealing the steel base of any item to the corrosion.

As mentioned by the galvanizer consultant companies, the hot dip galvanizing leads to the superior protection from any type of rusting or corrosion. The solid zinc-steel alloy layers of the hot dip galvanizing work as an effective barrier. If this barrier gets damaged, then the barrier of zinc works as a sacrificial anode and therefore prevents the corrosion. Additionally, the top most layer of this kind of galvanizing only comprises zinc. So, while it reacts with moisture, oxygen and carbon dioxide presented in the air, it creates a thin but strong film, which is known as zinc patina. It acts as the effective barrier over galvanized zinc coating and guards the item from possible corrosion.
