Since the establishment in 1993, Handu Steel Co., Ltd.
came to stand up as a company recognized for top quality
brand not only domestically but also in overseas by
steadily devoting itself to cold drawn tube production for
automobile and machine structural use.
By direct supply of with steel mills like POSCO and HYUNDAI
STEEL, We've secured the best quality and competitiveness
with synergy effect through total production system in
materials pipes to cold drawn tube production and post
component processing with systematic operation.
In Jinju Ibanseong Plant, where we produce our own
materials pipes.
Dangjin and Sabong Plant have 60,000 ton's capacity for
cold drawn tube production per year and we have another
processing facilities for automative parts.
Therefore, we will do our best to secure high quality for
precision cold drawn tubes, low cost basis and delivery
assurance and become the best cold drawn tube company
in the world.
Thank you.
