Electro Galvanized Steel, also known as Electro-Galvanized Iron (EGI), is a type of steel product that has undergone an electroplating process to apply a layer of zinc onto its surface. This method offers enhanced corrosion protection and improved aesthetics compared to uncoated steel.
Composition:
1. Base Material: EGI starts with a base substrate typically made from low carbon steel, which provides the necessary strength and formability.
2. Zinc Coating: A thin layer of zinc is deposited on both sides of the steel sheet through an electrolytic process. The thickness of this coating can vary according to the desired application, usually ranging from 5 to 40 microns.
Characteristics:
1. Corrosion Resistance: The primary characteristic of EGI is its resistance to rust and corrosion due to the zinc coating. While not as robust as hot-dip galvanization, it still provides effective protection for many applications.
2. Smooth Surface Finish: The electroplating process results in a smooth and uniform zinc layer, which enhances appearance and facilitates further processing such as painting or printing.
3. Formability: EGI retains the inherent formability of the underlying steel, allowing it to be bent, punched, or formed into various shapes without damaging the zinc coating.
4. Cost-Effectiveness: Compared to hot-dip galvanized steel, EGI is generally less expensive due to the thinner zinc coating and lower energy consumption during production.
Usage:
1. Automotive Industry: EGI is used in automotive parts such as interior trims, seat frames, and other components that do not require high levels of corrosion resistance but benefit from a smooth finish.
2. Appliances: It's found in white goods like refrigerators, air conditioners, and washing machines where lightweight, formable, and aesthetically pleasing materials are required.
3. Furniture: For making furniture parts such as chair legs, table frames, and metal cabinets, EGI offers good corrosion resistance and an appealing look.
4. Construction: In construction, EGI sheets may be used for drywall studs, roofing, and non-load-bearing structures requiring moderate corrosion protection.
5. Electrical Applications: Due to its conductivity, EGI is utilized in electrical appliances and as grounding strips.
6. Packaging: Thin EGI sheets can be used in packaging material, particularly when aesthetic appeal is important.
It's important to note that while EGI provides a cost-effective solution for mild corrosion environments, it is not suitable for severe exposure conditions where hot-dip galvanized or stainless steel might be preferred.
