Since the beginning of the new century, the economy of the world is steadily growing, the shipping industry is developing continuously and the global shipbuilding market shows a thriving momentum. With the complete industrial and scientific research system , stable fundamental of the industrial development and a long coastline, China has grand comparative advantages in the shipbuilding area. During the National Twelfth Five-Year Plan, the shipbuilding industry has been listed as a pillar industry of the national economy. After decades of development, the shipbuilding industry in China has significantly risen the share in the global shipbuilding market and become the world´s top three shipbuilding powers together with South Korea and Japan.
Shipbuilding section steel, the indispensable steel for shipbuilding and marine engineering, is widely applied to build bulk cargo ship, container ship, VLCC, cruise, warship and marine engineering platform. Shipbuilding section steel, the "reinforcement" which is welded on the deck, is widely applied to ship structure and plays a role in improving strength. In recent years, upsizing trend of ships becomes more and more obvious and the demand for Shipbuilding section steel also shows upsizing trend.
Steel ingot is applied to various forged parts for ships such as rudder stock, intermediate shaft, large hook and rudder pintle for ships. It has obtained Classification Society Certificates of Nine Countries;
Steel ingot is applied to various forged parts for ships such as piston head, piston rod and cylinder cover of diesel engines at medium and low speeds.
Technical Research and Development
