Abstract

See full text

Stainless steel sheets are plated with zinc and further phosphated so as to have chromaticness indices of L=45-53, a=0.0-0.4 and b=1.3-4.4. Thus treated stainless steel sheets have sufficient strength, excellent corrosion resistance and a color well harmonizing with other building materials and environment and do not suffer from color change for a prolonged period of time.
