PRODUCT DETAILS
A36 is an American standard specification for carbon structural steel (ASTM A36/A36M), primarily intended for plates, shapes, and bars in bolted, riveted, or welded construction such as bridges and buildings. Steel strip for tooling, springs, or shims is typically supplied under different, more specific standards (e.g., ASTM A109 for cold-rolled carbon steel strip, or spring steel grades).

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.
