Flat steel refers to steel with a width of 12-300mm, a thickness of 3-60mm, a rectangular cross-section and a slight blunt edge. Flat steel can be finished steel, and can also be used as blanks for welded pipes and thin slabs for stacked sheets. Main application: Flat steel can be used as a finished material to make hoop iron, tools and mechanical parts, and it can be used as a house frame structure and escalator in construction.
Packing and shipping

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.
