DIN Standard Steel Rail yekufambisa, njanji chinhu chakakosha, saka kuvimbika kwayo kunofanirwa kuvimbiswa. Sezvivakwa zvekutakura njanji, inch yega yega njanji inofanirwa kuve nechokwadi chemhando uye nemazvo, kuitira kuti ive nechokwadi chekuchengetedza uye kugadzikana kwechitima. Naizvozvo, kugadzirisa uye kunaka kwenjanji kunoda kutariswa kwakasimba uye kuyedzwa nenyanzvi uye tekinoroji vashandi.
Muchidimbu, sechikamu chakakosha chekutakura njanji, njanji ine hunhu hwesimba rakakwirira, kusagadzika kwekusapfeka, kusagadzikana kwecorrosion uye kuvimbika kwakasimba, inova kiyi yekuona kuchengetedzwa uye kushanda kwakanaka kwezvitima.
