Ste500 simbi ndiro

Bridge structural simbi DIN STE500 simbi ndiro inonyanya kushandiswa kugadzira riveted uye mabhaudhi bhiriji simbi zvimiro, senge mabhiriji emigwagwa mikuru, mabhiriji enjanji, mabhiriji egungwa, overpasses, viaducts uye mahombe emuchadenga emuchadenga cranes. DIN STE500 simbi ndiro, E giredhi bhiriji simbi inokodzera bhiriji zvimiro zvikamu zvakaoma uye zvine hutsinye mukupisa kwakadzika uye kutonhora nharaunda kana kutakura mitoro ine simba uye yakaoma kwazvo uye yakaoma masimba masimba.
