The steel industry should be trustworthy, self-disciplined, and obey the rules

On the one hand, entering a new era and stepping into the "14th Five-Year Plan", the high-quality development of Chinese steel will truly achieve a historic transformation from big to strong, and become a respected leader in the global steel industry. To achieve this goal, credit, self-discipline, and rules are indispensable. On the other hand, the current century-old changes are intertwined with the epidemic of the century, and the development of the steel industry is facing increasing uncertainties.

 

This year, the world's economic recovery momentum is still insufficient, and the Chinese economy is facing the triple pressure of supply shock, demand contraction, and weakening expectations. Under the situation of increasingly prominent uncertainty, resource constraints and environmental protection constraints, the steel industry is particularly self-disciplined. important.

 

For the industry, "trustworthiness, self-discipline, and compliance" requires the establishment of a long-term mechanism. The industry self-discipline mechanism is a higher standard of self-regulation, self-discipline and self-coordination within the industry, which is essentially a market-oriented measure.

 

Today, the steel industry, which has undergone the baptism of supply-side structural reforms, has become more resilient. In the future, our BBN will be firmly on the road.

 

S690QL is a BBN’S hot-selling steel plate.

 

Our S690Ql is a structural steel grade and is produced to give high yield strength during usage. The material can be heat treated using quench and temper techniques. These EN 10025-6 Plates have good forming and welding properties. S690QL plates have higher payload capacity and are energy efficient, hence can be used in leaner structures. This steel is used in other applications such as heavy transportation, construction industry, machine building, and lifting equipment.
