The BBNSTEEL company has the first-class qualification for steel structure professional contracting, integrating production, design and installation, and can undertake various steel structure projects. The product has a wide surface, flat and smooth surface, and neat trimming. It has users in more than 10 provinces and cities in China and is exported to the United States, Canada, Japan, Europe, Southeast Asia and other countries and regions.
BBN company has steel plates production workshops and warehouses with a total area of more than 500,000 square meters, and the total inventory of various types of steel exceeds 1 million tons. Relying on world-leading processing equipment and storage facilities, the company has strong steel production and processing capabilities, comprehensive logistics and logistics services, ensuring that it can efficiently complete more than 1 million tons of hot rolled plates processing business each year.
During the steel plate cutting, the special-shaped steel plate cutting process is often carried out. In this operation process, some cutting curves will be generated. Therefore, there should be relatively high precision standards during the processing of LR grade D seafaring ship steel. The operators need to have rich experience, and they also need to be proficient in the operation methods and working skills of the equipment, so as to ensure that the steel plate can meet the shape requirements after processing.
In 2013, one of our clients in Korea purchased 890 tons Q345B square tube from us for one building construction project. Our clients required no burr in the side of the tube, we finally produce the goods with great condition and +/-0.25mm tolerance for wall thickness, which is a very great tolerance with customers’ required size. Our square tube full available range is 2-16mm for wall thickness, and 40-500mm for width. In addition, our Q/C department will seriously control all of the process of every order.
LR grade D seafaring ship steel, No.45 seamless pipe belongs to high quality carbon structural steel. The carbon (C) content of No.45 seamless pipe is 0.42 ~ 0.50%, Si content is 0.17 ~ 0.37%, Mn content is 0.50 ~ 0.80%, Cr content is ≤ 0.25%, Ni content is ≤ 0.30%, Cu content is ≤ 0.25%. The tensile strength, yield strength, elongation, reduction of area and impact energy of No.45 seamless pipe are 600 MPa, 355 MPa, 16% and 40% respectively. No.45 seamless pipe is used to manufacture high strength moving parts.
Strengthen system construction. The system itself has a certain binding force, which specifies the rights and obligations of employees. It is a passive management means for employees. Its purpose is to promote each employee to develop good professional habits, form good behavior norms, and promote the improvement of enterprise management level.
