OEM/ODM Corten Steel Manufacturer & Exporter

Ningbo Puppet Steel Co., Ltd. is a leading global Steel Sheet Manufacturer and Cold Rolled, Hot Rolled & Galvanized Steel Supplier. We specialize in providing high-precision steel products, architectural materials, and complex customized metal solutions for clients globally. By integrating state-of-the-art metallurgical technologies with rigorous manufacturing protocols, we cater to highly demanding industrial sectors including municipal construction, structural infrastructure, heavy equipment manufacturing, automotive engineering, clean energy systems, and high-performance industrial components.

Strategically situated in the major coastal industrial hub of Ningbo, China, our advanced processing facilities run modern production lines coupled with continuous precision quality control inspections. Our product spectrum covers a comprehensive array of flat steel, specializing in cold rolled, hot rolled, galvanized, galvalume, and prepainted (PPGI/PPGL) steel sheets, in addition to carbon structural steels and high-performance weather-resistant weathering/Corten alloys.

Ningbo Puppet Steel Co., Ltd. leverage the massive infrastructure, technological efficiency, and logistical integration characteristic of China's primary manufacturing zones. The proximity of our plant to the Ningbo-Zhoushan Port—which ranks as one of the world's largest ports by annual cargo throughput—guarantees streamlined transport routes and immediate container shipping dispatch to transatlantic and transpacific trade lanes.

Installing weathering steel in distinct regional microclimates requires precise metallurgical knowledge and local engineering compliance. Corten steel performs optimally in alternating wet-and-dry cycles, which are necessary to form the protective oxide layer. In highly saturated coastal zones or areas with heavy salt spray, salt accumulation can inhibit the formation of the protective patina, potentially leading to accelerated degradation. To address this, Puppet Steel provides customized alloy mixtures containing higher nickel or chromium content to optimize corrosion performance in specific local conditions.

In terms of regulatory frameworks, we conform to regional structural directives across key international markets:

• North America (US & Canada): Complies with ASTM A588, A242, and AASHTO M270 specifications, satisfying local state DOT (Department of Transportation) material standards.
• European Union: Complies with the CE mark and EN 10025-5 standards, satisfying Eurocode 3 directives for structural steel design and environmental load considerations.
• Asia-Pacific: Matches AS/NZS 3678 (Australia/New Zealand structural standards) and JIS G3125, addressing local requirements for civil infrastructure and coastal industrial zones.
