نبشی به عنوان یکی از مشتقات آهن دارای دو مشخصه می باشد. اولین مشخصه آن طول بال و دیگری ضخامت بال نبشی می باشد. جدول اشتال نبشی با محاسبه هر یک از این مشخصه ها، وزن نهایی نبشی را به شما می دهد. به عنوان نمونه، نبشی 30*30*3 را در نظر بگیرید. در این ابعاد عدد 30 نشان دهنده طول بال نبشی که بر حسب سانتیرمتر می باشد و عدد 3 نشان دهنده ضخامت بال نبشی می باشد که این مشخصه بر حسب میلیمتر می باشد. استاندارهای  ابعاد در این محصول ISIRI 13968-1، DIN EN 10056-1:1998 و GOST 8510:1986 می باشند. استاندارد تلرانس ابعاد نبشی یه ترتیب ISIRI 1396 8-1 و  DIN EN 10056-2: 1994 می باشند. در نهایت می توان گفت استاندارد کیفیت سطح به ترتیب استاندارد ملی  ISIRI 9702-3 یا EN 10163-3 می باشد.
