We will continue to innovate and leap forward, create greater brilliance of the enterprise, and make our own contribution to the development of the S690QL material hardness steel industry.

Stainless steel is resistant to chemical corrosion, air or water and other weak corrosion media. Stainless steel covers ordinary stainless steel and acid resistant steel. S690QL material hardness, Ordinary stainless steel is generally not resistant to chemical corrosion, while acid resistant steel is generally stainless. The use of stainless steel is mainly to maintain the original appearance of the building for a long time.
