Hot Dip Galvanizing: The best galvanizing method

Hot dip galvanizing or HDG method is one of the most advanced methods of galvanizing used by the galvanizer companies. Besides, it is also a widely used procedure to protect the steel made or iron made metal surfaces from the corrosion. In this method used by the galvanizers, a four layered zinc coating is created electrochemically on a metal surface. Therefore, the iron or steel base is moved across the molten bath of zinc at the temperature of 460˚C. It allows the zinc to create a bond with the iron or steel base at any molecular level.

Additionally, as per the hot dip galvanizing consultant companies; the galvanized coating covers the total surface quite easily, including all the scratched, joints and the holes. Due to its effectiveness and the corrosion resistant properties; nowadays, the hot dip galvanizing process is used widely used in the numerous applications starting from the handrails, automotive body parts, and consumer appliances to walling and roofing. Besides, this HDG method is also used to shield the exterior panels as well as the automotive parts. Usually, this kind of galvanized strips made by various galvanizer companies are used in the cooling and heating duct systems in the buildings as well as in the metal pails.

As per the galvanizer consultant companies, it is completely recyclable with the less energy needed to process this galvanizing method for using to protect the corrosion. So, it can be used as the ultimate material by the galvanizers in order to protect the structures of the parks, airports and the waterways of the various countries and states. Here, in this article, we have put together several advantages of this HDG procedure over the other methods of galvanizing. Read along to know more:

  • According to the hot dip galvanizing consultant companies, this method of galvanizing offers the advantage of having low initial costs over the other techniques of corrosion protection. Besides, this process also includes lesser labor intensive while comparing to the other procedures.
  • The coatings of this process enjoy the expectancy of a much higher life of around 40 years and more even in the severe urban and coastal environments. Additionally, this kind of performance and life expectancy of this process are also easily predictable.
  • In some rare cases, the process of hot dip galvanizing includes a higher initial charge, but then also it is much more cost effective than the other methods of galvanizing as it is more durable along with the little maintenance requirements. As this method provides superior resistance to the mechanical and water damage as well as the abrasion damage during erection, service and transportation.
  • Another important advantage of this method is that it is quite straightforward, closely controllable and simple. Besides, all the coating thicknesses are predictable, easily specifiable and regular. All these features enable this method to be precise during design and usage.

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.
