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.
