3.2. The relation between coating weights and corrosion resistance properties in W.R.Alstar, 55% Al-Zn and Galvanized:
Fig.-1 shows the relation between coating weights and the lapse of time until red rust occurs in W.R.Alstar, 55% Al-Zn and Galvanized as obtained through salt spray tests (testing conditions; 5% NaCl, 35ºC). The figure indicates that W.R.Alstar has better corrosion resistance properties than 55% Al-Zn and Galvanized.
