DaehanSteel Co., Ltd. has been producing semi-processed
billet, deformed bar-which has better adhesion to concrete
bar in coil-which is capable of continuous rebar processing
and processed rebar which is effective for shortening
the construction period.
Bar in Coil
One bundle of bar in coil is about
2,200 meters. (equivalent to 275
rebar pieces of 13mm D, 8 meter
length) Improved production facilities
which reduced material replacement
time and ability of continuous
processing of rebar has increased its
productivity and decreased loss.
Certificates: KS D 3504, MS146, AS/NZS 4671
Reinforcing Bar
Reinforcing bar is commonly used
construction material needed for
building concrete structures.
Concrete is strong at compressive
force but weak at tension. In order to
cover up the weakness, reinforcing
bar is placed into the concrete to
boost compressive force and tension.

Steel Making Process
Steel making process is a process of making semiprocessed billet. During the process, steel scrap is melted,
impurities are removed, chemical components are adjusted
and then product is manufactured with uniformed shape.
DaehanSteel is producing 1,400,000 tons of billets annually.

Insertion of Scrap
EScrap is commonly called as ‘scrap
metal’. Scrap is precious resource
in steel making, consisting of more
than 70 percent of production cost.
DaehanSteel pays attention to stable
supply and treatment of scrap. We
also take strict tests and inspections
on scrap from its delivery to
insertion, to ensure excellent quality.

Rolling Process
Your Steel Advisor.
Rolling processing is a process in which the billet
previously produced is reheated, processed and then
made into the product of the size and shapes according
to customer’s requirement. DaehanSteel is currently
producing 1,550,000 tons of steel products annually.
