why is the process of galvanizing steel important to the court's decision course hero

by Beverly McDermott II 6 min read

Galvanizing steel is the process of submerging steel in a bath of molten zinc which creates a protective layer that prevents future corrosion. Rust is potentially dangerous and can cause metal parts to become stiff and weaken the integrity of the metal and thus the structure.

Full Answer

What is galvanization and how does it work?

Galvanizing is an effective, low-cost way to improve the durability of bare steel, resulting in a surface. finish that is more durable than paint alone, yet accepts paint as an additional layer of protection. CSI’s hot-dipped-zinc coating capabilities are found in two lines: the #1 Continuous Galvanizing Line (CGL)

Why is steel chemistry important in the hot-dip galvanizing process?

Apr 08, 2011 · April 8, 2011. Authored by Bernardo A. Duran III. Galvanized coatings are formed by a chemical process during which steel and zinc metallurgically bond, forming a series of corrosion-inhibiting, highly abrasion-resistant zinc/iron alloy layers. Galvanized coatings are specified for their corrosion resistance.

How do the elements in steel affect the galvanizing process?

Mar 22, 2018 · The preparation of the steel surface is vital to galvanizing. Any faults or inadequacies on the material will become apparent because the zinc won’t react with the surface, leaving problem areas uncoated. Degreasing is the first step of surface preparation for galvanizing steel.

What determines the appearance of galvanized coatings?

Sep 14, 2020 · Hot-dip galvanization for steel not only protects metals from corrosion but also improves maintenance-free longevity. Thus, in the long run, businesses are saving money by keeping their steel galvanized and protected. In addition, the galvanization process is environmentally-friendly and resistant to conditions. Galvanizing Steel: Three Main Steps

What is the process of galvanizing steel?

Step-by-Step Galvanizing Steel Process. Galvanizing steel is the process of submerging steel in a bath of molten zinc which creates a protective layer that prevents future corrosion. Rust is potentially dangerous and can cause metal parts to become stiff and weaken the integrity of the metal and thus the structure.

Why is hot dip galvanized steel important?

Hot-dip galvanization for steel not only protects metals from corrosion but also improves maintenance-free longevity. Thus, in the long run, businesses are saving money by keeping their steel galvanized and protected.

How to prepare zinc for coating?

Step 1: Surface Preparation. The first and most crucial step is preparing the surface of the material for the coating process. Zinc will not react to unclean metal, so a successful surface prep is a must. Preparing the steel begins by removing all the dirt, grease, and other contaminants from the metal surface.

What temperature does zinc react with?

After the surface of the metal has been prepped, it’s submerged in a large bath of 98% pure molten zinc at 830° F. The zinc reacts to the clean metal and generates a protective layer.

What is the best way to measure coating thickness?

There are two different procedures that can be performed to measure the coating’s level of thickness: magnetic gauges or optical microscopy. Magnetic thickness gauge is the most simple and non-destructive thus making it the most popular method.

What is the last component that is inspected?

As mentioned before, zinc will not react to unclean metal. Thus, the steel’s appearance and finish provides useful information such as revealing any errors that occurred during the galvanization process.

What is hot dipped galvanizing?

However, the most common method that is used nowadays is hot-dipped galvanizing. It has been proved to provide more lasting and maintenance-free protection for metals since 1742.

What is galvanized pipe used for?

Galvanized iron pipes are widely known for a wide range of practical applications — water transportation, in agriculture, telecommunications, plumbing, and more. Galvanized iron pipes are great to utilize because of its corrosion resistance and its durability for both indoor and outdoor use.

How to clean a steel pipe?

Firstly, the steel is cleansed with the use of a caustic solution — a corrosive substance in where it will completely remove all oil, grease, dirt, and excess pain. After the caustic solution is rinsed off, the iron pipe is then pickled.

Can you cool down galvanized iron pipes?

After the zinc dipping technique is done, it is now time for the galvanized iron pipes to cool down. Typically, the galvanized iron pipes are cooled in a quench tank for it to cool down quickly and restrain unwanted effects of the newly formed coating with the atmosphere of its surroundings.

What are the advantages of galvanized steel?

The 3 main advantages of galvanized steel: R. Advantage 1: The price. Compared to stainless steel, galvanized steel is much more cost-effective. R. Advantage 2: Durability. Depending on the environment to which the galvanized metal is exposed, its service life can be up to 75 years. R. Advantage 3: More protection.
