ABSTRACT:
A weather-resistant strip roofing material having improved corrosion-resistant properties includes a strip of stainless steel which is pre-treated by an aggressive pickling process and/or a chemical activating process prior to applying a hot-dip tin coating, The pre-treatment of the stainless steel strip produces superior alloying between the stainless steel and the tin coating which reduces flaking of the tin coating.
