Hot-dip galvanizing is a process that consists of the application of a superficial zinc coating on an iron and steel element by immersing molten zinc at a temperature of 450°C. The objective of this process is to achieve the protection of the pieces or metallic elements against corrosion due to humidity and/or environmental contamination.

Galvanneal is a process where steel is dipped in a hot zinc bath (similar to the Galvanizing process), then undergoes a secondary process in which iron is annealed with the zinc coating to create an iron - zinc on the metal surface. Galvanneal provides greater benefits in processes such as weldability, paintability, formability, and corrosion resistance.

We operate two plants in Pohang and four in Gwangyang to produce cold rolled steel. Applications for cold rolled steel range from household appliances, including motor vehicles, washing machines, and refrigerators, to industrial and architectural uses. Also, as new applications for this steel emerge, including steel cans and steel houses, we are focused on delivering higher value-added products and expanding their applications.

The electrogalvanization of steel consists of electrolytically depositing a layer of zinc by submitting the steel to a coating process by immersion in zinc salts with inert anodes and cathodes. This process allows for a uniform and fine, high-quality coating for corrosion protection .

Non-oriented electrical steel (NO) is an electrical steel sheet that has uniform magnetic properties in the rolling direction and other directions, and is classified as Hyper NO, High NO, etc. to the guaranteed iron loss standard. If it is Hyper NO, if it is less than 6.0 W/kg, it is called High NO product. It is widely used, from large generators to small precision motors, iron core materials for rotating machines, and iron core materials for small transformers.

The HPF coating. (Hot Press Forming) process uses steel sheets heated before press forming, and when formed at high temperatures, the steel sheet is very soft, making it easy to process difficult-to-form shapes. In addition, after molding, by cooling rapidly in the mold, the processed part is a high-strength product (150 kgf/㎟) and prevents the steel plate from rusting while it is heated at a high temperature through the aluminum coating.

The 89% Al-9% Si alloy is hot-dipped onto a cold-rolled steel sheet. It has excellent heat resistance compared to zinc plated steel sheet and cold rolled steel sheet, and has excellent weather resistance/corrosion resistance/It has heat resistance/corrosion resistance and is applied to household appliances and exhaust system parts.
