The nation’s first 50-ton blast furnace operation [1965]
The first domestic electric arc furnace [1966]
The first domestic production of steel plates [1971]
Now the nation’s first integrated mill in Brazil,
Dongkuk Steel opens up new era of steel with the first spirit.
Dongkuk Steel, with its 40-year-history of steel plate production, is
a strong technology enterprise leading high quality steel industry.
Researchers at its state-of-the-art R&D center are doing their best
to develop high value-added steel products and manufacturing
technologies with their "creating masterpiece" spirit.
First strong
trustworthy products
From needles to vessels, with 56 year of single path in steel
craftsmanship and state-of-the-art facilities, Dangjin Works now
introduces high grade focused steel products being used in offshore
structure, special and mega vessel. Dangjin Works will create new
legend in steel industry with its best products.
HigH “Concentrating on what we do the best”
Dongkuk Steel, a traditional company in Korean steel industry, can do the
best in nothing but steel. It manufactured steel plates first time in Korea
and pioneered steel market. In late 1990s through Pohang Works equipped
with 2.5 million tons of annual steel plate production capacity, Dongkuk
Steel opened up steel plate production system for shipbuilding and has
lead domestic steel plate market. As of year 2010, Dangjin Works, equipped
with 1.5 million tons of annual steel plate production capacity, begins new
operation and opens new era of high grade steel plates.
Dangjin Works enterd into commercialization of its strategic
products with first shipment of steel plates for shipbuilding on
March 18, 2010. Following this success, Dongkuk Steel’s steel
plate business was upgraded from annual 2.9 million tons at
Pohang Works to a total of 4.4 million annual tons of production
system. Combined 40 years of steel plate know-how by Dongkuk
Steel with the latest technology, Dangjin Works is a production
base for next generation strategic products. By constantly sup-
plying the best quality steel plate products proven by the high-
est level customers, Dangjin Works will achieve a win-win with
customers.
dongkuk steel has manufactured steel plates first time
in korea. striving only in the area of steel and getting
ready for global competitiveness, dongkuk steel has
grown itself into a world-class steel manufacturer by
introducing advanced technologies and upgrading pro-
duction facilities.

Dangjin Works is a 1.5 million tons of annual capacity production
base for Dongkuk Steel’s next generation strategic products
with the latest and the best steel plate production infrastruc-
ture.
Dangjin Works will produce high grade steels such as wide
width steel plates for shipbuilding, TMCP (Thermo Mechanical
Controlled Process) steel plates, heat treated steel plates, high
tensile steel plates, which will account for over 50% of its total
production, thus leading the upgrade of steel plate market.
1,500,000 Tons
Dangjin Works is equipped with an exclusive pier capable of
berthing 50 thousand ton vessel. Production facilities from raw
materials placement to product shipping at Dangjin Works are
arranged in straight line of 1.2 km to improve efficiency. Dangjin
Works is also the most up-to-date with environment friendly ap-
proach by using natural gas.
Dangjin Works produces high grade oriented steel plates be-
ing used in special vessel, offshore structure, mega vessel and
building. For steel plates used in mega vessel, it is crucial how
uniformly the plates are produced with desired thickness. Dan-
gjin Works’ plate mill is one and only place where steel plates of
4,800 mm width, the largest standard in Korea, and of 4.5 to 150
mm thickness size can be manufactured.

place where a number of steel manufacturers and dis-
tributors are located and with its advantage in traffic
convenience, is fast emerging as a steel mecca. dangjin
Works has established a high grade oriented production
system and has started manufacturing high grade steel
plate for shipbuilding. dangjin Works, as a next genera-
tion production base for dongkuk steel, will do a leading
role in establishing a steel belt connecting korea and
Brazil with the construction of an integrated mill in Bra-
zil first time in korea.

of 12,903㎡, has one research and two laboratory units. No. 1
lab is a huge laboratory with testing ground for melting such as
vacuum induction melting and casting furnace and pilot testing
ground for hot rolling. The R&D Center is equipped with various
kinds of testing equipment such as testing ground for material
quality and property with tensile and fatigue testing machine,
common milling machine, and welding testing ground. Under
the banner of "A passionate and innovative research institute
creating new technologies and values", the R&D Center will ex-
pand the work force to over 100 researchers in a few years. The
R&D Center will maximize the synergy effect by combining Dan-
