Continuous Galvanization
Using techniques perfected
by years of experience, Dongbu Steel’s hot-dip galvanized steel
sheet is formed on a line that is continuously galvanizing to guarantee
smooth, high quality end products.
Dongbu Steel is committed
to offering galvanized steel sheet with a broad range of base metal
qualities, including commercial, lock forming, drawing, and structural
quality. Moreover, each product undergoes a chromatic process for
protection against rust.

|
|
Superior Formability
Highly workable steel sheet and
strips are used as base metals for all galvanized steel sheet produced
at the Cold Rolling Facility of Dongbu Steel. The base metals in
coil are continuously annealed, galvanized, and properly leveled.
The galvanized sheet provides superior formability with base metals.
|
|
|
|
|
|
Excellent Corrosion Resistance
All galvanized steel
sheet is treated with chromic acid for protection against rust,
to maintain original surface luster for a longer period.
|
|
|
|
|
|
Consistent Quality
Production is carried out using
a rigorous quality control process and a strict quality inspection
based on high quality production standards. As a result, product
quality, dimensions, and other properties strictly conform to customer
demand.
