 Product Features |
 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.
