Scope of Application
ASTM A283 steel plate is a kind of low carbon steel with high strength and good formability. It is easy to process and manufacture, and can be safely welded by various welding methods. ASTM A283 steel plate is a structural carbon steel plate used for low or medium tensile strength applications. ASTM A283 steel plate is used in the manufacture of riveted, bolted and welded structures for storage tanks and cryogenic control vessels, bridges and buildings, including prefabricated buildings, warehouses and industrial commercial structures.
Packing and shipping
Our company has passed ISO9001 quality management system certification, Our Mill product with CE/EN10204 / ASTM/Classification society certificate/CASO/BIS etc certificate.All the customers give good appreciation to our products.We are glad to be your good partner.
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.
