Kalitesiz galvanizli \u00e7elik bobinler genellikle d\u00fczensiz renk g\u00f6sterir; baz\u0131 b\u00f6lgeler (ince bir \u00e7inko tabakas\u0131 nedeniyle) ana metal rengini g\u00f6sterirken, di\u011fer b\u00f6lgeler \u00e7inko c\u00fcrufunun birikmesi nedeniyle mat ve p\u00fcr\u00fczl\u00fcd\u00fcr.
