The shipbuilding use GL-D hull structural steel plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The shipbuilding use GL-D hull structural steel products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.
Under the action of the roller and the plug, a cavity is formed in the blank, which is called the blank. Then send it to the automatic tube rolling machine to continue rolling. Finally, the wall thickness of the whole machine is equalized and the diameter is calibrated by the sizing machine to meet the specification requirements. It is an advanced method to produce shipbuilding use GL-D hull structural steel, hot-rolled seamless steel tube by continuous rolling mill.
Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.
GB711-2011 Chinese steel standard is used in the manufacture of steel plates with a shipbuilding use GL-D hull structural steel thickness of not more than 150mm for navigating ships, fishing boats and marine engineering structures in ocean, coastal and inland waterway areas. CCS/NV/GL550 steel is a structural steel for ships and marine engineering, divided into four quality grades A, D, E, F, namely AH550, DH550, EH550, FH550, H is high-strength building materials, and 550 is the lower yield strength.
