At the same time of doing well in EN steel grade S275N material production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the EN steel grade S275N material technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with EN steel grade S275N material ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.
