What is a galvanized steel coil and how is it made?
A galvanized steel coil is formed by coating a steel sheet with a layer of zinc to mitigate probable case of corrosion. The higher the quality of zinc alloyed on the steel sheet, the greater the dampening of elemental rust such as moisture. The coating also enhances the durability of the steel sheet. In terms of manufacturing, hot-dip galvanization in which the zinc is molten is preferable for thicker applications, while for finer applications where a smoother finish is required, smoother surfaces electro-galvanization is recommended.
Understanding the galvanization process
Galvanization improves the steel materials against corrosion. It increases the life span of the parts as pre-coated galvanized steel is more rust-resistant. Coating steel with zinc via hot dip galvanization or electro-galvanization protects the steel from moisture and oxidation. Construction industry uses galvanization for commercial structural steel and structural roof decking. Automotive industries use the process too on parts to increase the life span of the parts on the car. There are two types of methods: hot dip and electro galvanization. Hot dip has a greater ability resist against corrosion and is ideal for heavy-duty outdoor projects, while electro-galvanization is good for fine detailed parts. Both offer a balance cost and value for the engineering industry.
The role of zinc coating in protecting steel
If applied correctly, zinc coating nearly completely shields steel from corrosion while improving longevity and performance across a plethora of environments. The processing of galvanization is essentially Microsoft’s Paint for zinc because it istantly applies a barrier that protects and blocks moisture and oxygen from reaching the steel, the main reasons why rust forms. Furthermore, zinc also applies cathodic protection, meaning it will sacrifice itself by corroding instead of the steel, thus prolonging the time before the structure begins to fail. Because of this, zinc-coated steel is heavily used in construction and automotive manufacturing where there is little to no room for mistakes over the life of the metal.
Hot-dipped vs. electrogalvanized steel coils
Hot dip galvanized steel coil strip is formed from steel/HRC that is first dipped into zince. This process electroplate steel into galvanization allowing the zinc to bond into the steel creating a protective coat that makes it long-lasting and stronger. In harsh atmospheres requiring high durability and corrosion resistance, hot dipped coils do the job well. The crown like coating strengthens the functionalities of outdoor frameworks such as structural parts and installations.
On the other hand, electro galvanized steel coils are made through the process of electroplating which involves coating the steel with zinc using electrical current. This technique provides zinc deposits of lesser thickness which have a smooth contour and polish. While electro galvanized coils have good corrosion resistance, they are best suited for internal applications or where aesthetics and close manufacturing tolerances are more important, such as in electronics, appliances, and light automotive parts.

Understanding coating weights and thickness
For galvanized or coated steel products, coating weights and thickness are critical components since they greatly impact longevity, resistance to corrosion, and function. Coating weight indicates the total weight of coating material deposited on a given area of the surface, which in most cases, is stated in ounces per square foot (oz/ft²) or grams per square meter (g/m²) based on local practice. Thickness is applied to the coating in form of a layer, and is usually given in microns or mils.
Selection is done with consideration of the relationship between coating weight and environmental conditions with respect to the anticipated Coating Weight Per Unit Area (CWPUA). In most cases, higher coating weights offer greater protection at a higher expenditure or other undesirable material traits. Minimum acceptable values standards are set for specific applications by industry standards such as ASTM A653 or ISO 1461.
