Industry Overview
Marine engineering refers to a new construction, reconstruction or expansion project located on the seaway side of the coastline for the purpose of developing, utilizing, protecting and restoring Marine resources. It mainly includes the construction of offshore platforms and artificial islands, such as oil and gas exploration and exploitation platforms. Since the second half of the 20th century, the world's population and economy have expanded rapidly, and the demand for energy has also increased sharply. With the exploitation of oil and gas in the continental shelf waters, as well as the continuous expansion of Marine resources development and space utilization scale, the Marine engineering corresponding to it has become one of the rapidly developing projects in the past 30 years.

Inverted Angles
Product application
L-shaped steel, also known as unequal edge and unequal thickness Angle steel, is a new type of profile produced to meet the needs of large ship construction. In addition to being used in large ships, L-shaped steel can also be used in Marine engineering structures and construction structures with high requirements.
Ingot products are used in climbing gear boxes, pins, lifting rack and other forgings of offshore platforms.
Technical research and development
Multi-channel special-shaped high-pressure water descaling technology meets the technical specifications of international shipbuilding industry PSPC.
Professional TMCP rolling technology can be used proficiently to keep final rolling temperature being firmly controlled under the austenite recrystallization temperature, and the toughness of the finished product is fully optimized.
Double straightening + strong straightening is becoming perfect to ensure that the straightness accuracy of each Marine section steel is less than 1‰， reaching the international advanced level.
NJB400 ball flat steel independent research and development to achieve localization instead of imports, advanced technology and high-end technology to be fully affirmed.
The intelligent detection system fully realizes the whole process monitoring and management of section steel quality and manufacturing process.
