Since the beginning of this century the invention of stainless steel, stainless steel is the reputation of the image of modern materials and construction application of the collection in a body, its competitors envy. Stainless steel does not produce corrosion, pitting, corrosion or wear. Or building materials in one of the highest strength of metal materials of stainless steel.Because the stainless steel has good corrosion resistance, so it can maintain the structural components of the integrity of engineering design permanently. Chromium stainless steel is set high mechanical strength and Gao Yanshen in a body, manufacturing easy parts, can satisfy the requirement of the architects and structural designers.
