Company introduction: Dear Prospective Buyers: Thank you very much for your interest in HYSCO, an enterprise specializing in the manufacture of automotive steel sheet. Humanity has passed through the Stone Age and the Bronze Age, and we are now living in a civilization reliant on the forging and shaping of metal. Most of people tend to think that the steel industry is distantly removed from their everyday lives. But if you look around closely, you can easily see how deeply steel and iron are imbedded in almost every facet of our daily routine. Thus, archeologists have named this historical period the "Iron Age." HYSCO is a company that produces automotive steel sheet and various steel pipes. Of our numerous steel-based products and equipment, we largely focus corporate efforts on these two particular areas. HYSCO was first established as Kyung-il Industrial Co., Ltd. in 1975 and later renamed as Hyundai Pipe Co., Ltd in 1980. In 2001, on the cusp of the 21st century, we renamed the firm once again as HYSCO. In response to rapid changes in the steel industry and as befitting our position as a global leader, we have concentrated efforts on the uplift of profitability while still making a rich contribution to society. The cold rolling mill started commercial operation in 1999, and is a representative part of such change and progress. We would like you to watch our dynamic progress. With your constant interest, HYSCO promises to become the world? best manufacturer of automotive steel sheet and high value-added steel pipes. Thank you very much.
