Bengang Group's electro-galvanizing unit was put into production in 2012. It is one of the four large electro-galvanizing units in the country and the only electro-galvanized sheet production line in the north of the Yangtze River. This unit aims at the development trend of the world's electro-galvanized products. The product is positioned to produce high-quality, high-value-added automotive steel and high-end household electrical appliances. However, due to the lack of process technology and the lack of equipment functions, the unit has been able to produce only a single low-end fingerprint resistant product, which has not reached its original design capacity and profitability level.
“It was put into production in 2012 and it took 5 years. The product quality has not been effectively improved. The production line has not been able to reach the production efficiency. What happened to the electrogalvanized sheet production line?” “Same as the Baosteel electrogalvanized production line, but it can only produce a single For fingerprint home appliances, where will Bengang's electro-galvanized production line go? "" What is the future development of electro-galvanized products? Do you choose to temporarily suspend production or continue to invest? "In July 2017, at the managerial meeting of Bengang Group, it came from time to time. The atmosphere of the discussion was particularly warm. At that meeting, the galvanizing line ushered in a life-and-death choice.
"In 2017, China's focus was on promoting supply-side structural reforms. At the same time, as the country fully promoted" Made in China 2025, "the steel industry ushered in new development opportunities."
