Steel Galvanization: Advantages and Applications in Various Industries
When a coating of zinc is applied to prepared steel or iron to offer it protection and prevent corrosion or rust, it is referred to as the process of galvanization or galvanizing. There are different ways to galvanize pieces of metal, but the most popular form is known as hot-dip galvanizing.
Galvanized steel is arguably one of the most popular and useful metals because of its longevity and durability, and its ability to be used in many different applications. For these reasons, it is often the preferred metal of choice in many industries, including the automotive, construction, agricultural, and solar industries, to name a few.
In this article, we at Armco Superlite will explain some of the many benefits of using galvanized steel and expand on some of the industries that use this versatile material.
4 Principal Benefits of Galvanization and Galvanized Steel
Here are four of the biggest benefits of galvanized steel:
Initial Investment Savings:
Galvanized steel offers the lowest initial cost in comparison with most treated metals. Additionally, it does not require preparation of the surface, painting of the surface, or additional coatings, and it is ready to use upon delivery. This saves on labour and other on-site costs.
With galvanization, industrial steel can be expected to last longer than 50 years in average weather conditions. There is little to no maintenance required over this period, saving on coating applications and increased material costs through the decades.
Zinc is the Sacrificial Anode:
Even if the steel is fully exposed through a scratch or chip, the zinc will corrode first. The coating will corrode in favour of the steel, offering sacrificial protection to the damaged areas, and will ensure that the steel remains protected.
Resistant Towards Corrosion:
The iron elements in the steel are prone to rusting, but the zinc coating is not and acts as a protective barrier between the iron and moisture or oxygen, the main causes of rust. Galvanization protects the underlying metal, including recesses and sharp corners.
4 Industries that Frequently Use Galvanized Steel
Here are four industries that often use galvanized steel:
Solar and Wind Industries:
Once installed, solar and wind projects need continuous workflow, and any repairs or maintenance creates disruption and revenue losses. Hot-dipped galvanized steel is preferred because of this and the corrosion protection it offers. Furthermore, because of its longevity, it needs replacing less often and, therefore, it is environmentally friendly too.
Hot-dipped galvanizing offers protection that often lasts for decades, even when exposed to the rugged agricultural sector. Galvanized steel is often used in this industry because farming tools are often left out in the elements and are susceptible to corrosion, creating a need for more resilient equipment.
The use of galvanized steel in this industry is obvious. Since up to 80% of a vehicle can be made of various types of metals, the need to prevent rust is vital. Making use of zinc-covered steel assists in preventing corrosion and is a favourable selling tool for vehicles that are manufactured with it.
Arguably one of the largest users of galvanized materials is the construction industry. The attractive aesthetics revealed in the “shine” of the metal gives a cosmopolitan feel to modern buildings and is often used in architectural designs. Additionally, it can provide a high level of protection and cover or be used for gutters, fencing, and more.
