SURFACE TREATED ZINC-BASED METAL PLATED STEEL SHEET

摘要

A surface treated zinc-based metal plated steel sheet which has an electrically conductive intermediate layer free of chromium on a zinc-based metal plating layer and an organic resin layer on the intermediate layer. The steel sheet not only is a so-called chromium-free surface treated steel sheet, but also is significantly excellent in both conductivity and corrosion resistance. Accordingly, the steel sheet is almost free from the danger of water contamination and can be used in a variety of applications in place of conventional chromate-treated steel sheet.
