The production line adopted many advanced technologies and becames the fifirst intelligent unit in the private cold-rolled stainless steel industry. The second phase annual output of 500,000 tons of stainless steel hot rolled acid pickling line and annual output of 300,000 tons of cold rolled production line will put into hot load test run on August 2020. At the same time, the company established a strategic partnership with Guangqing group to achieve the effffective integration of production, supply and marketing resources.
