Corrosion resistance comparison with post hot-dip zinc-coated steel sheets (HDZ55: JIS H8641)
With only 1/6 of the coating weight of post hot-dip zinc-coated steel sheets, ZAM® exhibits corrosion resistance equal to or better than theirs. The following examination certifications admit that ZAM® may replaceposthot-dip galvanized steel.
Appearances of flat parts after salt spray test
Post hot-dip products are first cut to shape and then coated.
Corrosion resistance comparison in a sulfur dioxide environment
ZAM shows better corrosion resistance compare to post hot-dip zinc-coated steel sheets (HDZ55) in a sulfur dioxide (sulfurous acid gas) environment.
Appearances after 450 hours of sulfur dioxide test
