| Note | • SGCH is a hot-dip galvanized steel grade per JIS G 3302, with zinc coating for corrosion resistance. • It is not equivalent to cold-rolled grades such as DC01, ST14-16, or DC03-06. • Surface treatment is hot-dip galvanizing, not chromated anti-finger treatment. • Its mechanical properties are based on the cold-rolled substrate (e.g., SPCC). |

Application Areas
Steel is widely used in steel structure workshops, bridge frames, main structures of high-rise buildings, and infrastructure construction (such as highways, oil and gas pipelines). Its high strength properties ensure load-bearing stability and seismic performance. In ship manufacturing, steel is used to build hull structures, decks, and internal components. Hot-rolled coils rely on their load-bearing capacity to adapt to harsh environments.
Factory workshop
With a commitment to excellence, innovation, and sustainability, the company has established itself as a trusted partner in the international steel industry.After nearly two decades of relentless endeavour, our client base now spans over 110 countries and regions across Europe, the Middle East, South America, and Southeast Asia.
