The company attaches great importance to systematic management, and has passed the S460NL grade specification ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on S460NL grade specification quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.
Cold-rolled S460NL grade specification steel plates are used for parts that require a large degree of plastic deformation of the material when forming parts, and there must be no wrinkles, cracks, etc. on the surface. For different parts, use different grades of steel plates. For example, the Japanese automotive S460NL grade specification steel sheet standard is divided into three categories. The first category (SPCC) is ordinary cold-rolled steel sheet, which is usually rolled by rimmed steel, the second category (SPCD) is rolled steel sheet, and the third category (SPCE or SPCEN) ) Is a cold rolled steel sheet for deep drawing.

Since March 20, 2020, the export tax rebate rate of some steel products in China has been increased. According to statistics, the export volume of S460NL grade specification and so on steel products within the adjustment scope in 2019 is 18.888 million tons, accounting for 29.4% of China's total steel exports; the export volume is 14.05 billion US dollars, accounting for 26.1% of the total steel exports. The adjustment will be conducive to the export of some steel products in China and reduce the purchase cost of foreign customers.
