FAQ of Hot Dipped Galvanized Steel Coil

1.Is hot dipped galvanized steel same as galvanized?
Hot-dipped galvanized steel is a type of galvanized steel. Hot dipped galvanizing process is practical, and hot dipped galvanized product is very durable, versatile and highly corrosion-resistant.

2.What is the difference between G60 and G90 for galvanized steel?
G90 galvanized steel are coated by the coating weight of zinc 0.90 oz/ft^2 while G60 galvanized steel are 0.60 oz/ft^2. That is to say, G90 galvanized steel are coated by the weight of zinc 275g/m^2 while G60 galvanized steel are 180g/m^2.
Therefore, G90 galvanized steel are more 95g/m^2 zinc coating than G60 and then a longer service life.

3.What are galvanized steel coil used for?
Hot dipped galvanized steel coil are most produced to roofing sheet for construction and houses.

4.How are galvanized coils made?
Hot dipped galvanized steel coil are made from cleaning and heat-treating cold rolled coils and then are zinc coated from zinc pot. Through this process, cold rolled steel coil are plated with zinc for anti-rust.

5.How long will galvanized steel coil last?
The zinc coating of hot-dipped galvanized steel will last 10 to 30 years in the open environment. High humidity and temperature have less life time for galvanized steel coil.

In the world of steel manufacturing, galvanized coils play a crucial role in various applications, from construction to automotive industries. As a leading galvanized coil manufacturer, Jindalai Steel Group specializes in providing high-quality galvanized steel coils, including DX51D galvanized coils, hot dip galvanized steel coils, and electro galvanized coils. This article aims to shed light on the characteristics, manufacturing processes, and selection criteria for galvanized coils, ensuring that you make informed decisions for your projects.

What Are Galvanized Coils?

Galvanized coils are steel sheets that have been coated with a layer of zinc to protect them from corrosion. This process enhances the durability and longevity of the steel, making it suitable for outdoor applications where exposure to moisture and environmental elements is a concern. The two primary methods of galvanization are hot dip galvanizing and electro-galvanizing, each offering distinct advantages.

Hot Dip Galvanized Steel Coils

Hot dip galvanized steel coils are produced by immersing steel in molten zinc. This method creates a thick, robust zinc coating that provides excellent corrosion resistance. The thickness of the zinc layer is a critical factor in determining the coil’s longevity and performance. A thicker zinc layer offers better protection, making hot dip galvanized coils ideal for heavy-duty applications.

Electro Galvanized Coils

In contrast, electro galvanized coils are coated with zinc through an electrochemical process. This method results in a thinner zinc layer compared to hot dip galvanizing. While electro galvanized coils may not offer the same level of corrosion resistance as their hot dip counterparts, they are often preferred for applications requiring a smooth finish and precise dimensions.

Understanding Zinc Flowers

One of the unique characteristics of galvanized steel coils is the formation of “zinc flowers.” These are crystalline structures that appear on the surface of the galvanized coating. Zinc flowers can be an indicator of the quality of the galvanization process. A well-executed galvanization will produce a uniform and aesthetically pleasing zinc flower pattern, while irregularities may suggest issues during manufacturing.

How to Distinguish Between Galvanized Coils

When selecting galvanized steel coils, it is essential to consider several factors:

1. “Type of Galvanization”: Determine whether you need hot dip or electro galvanized coils based on your application requirements.

2. “Zinc Coating Thickness”: The thickness of the zinc layer plays a significant role in corrosion resistance. For outdoor applications, a thicker coating is advisable.

3. “Surface Quality”: Inspect the surface for uniformity and the presence of zinc flowers. A consistent appearance indicates a high-quality product.

4. “Manufacturer Reputation”: Choose a reputable galvanized coil supplier like Jindalai Steel Group, known for its commitment to quality and timely delivery.

The Manufacturing Process of Galvanized Coils

The manufacturing process of galvanized coils involves several key steps:

1. “Surface Preparation”: The steel substrate is cleaned to remove any contaminants, such as oil, rust, or scale. This step is crucial for ensuring proper adhesion of the zinc coating.

2. “Galvanization”: Depending on the chosen method, the steel is either immersed in molten zinc (hot dip) or subjected to an electrochemical process (electro galvanizing).

3. “Cooling and Inspection”: After galvanization, the coils are cooled and inspected for quality. This includes checking the thickness of the zinc layer and the presence of zinc flowers.

4. “Cutting and Packaging”: Finally, the galvanized coils are cut to the desired dimensions and packaged for delivery.
