Sannadkan, meelo badan oo dalkeenna ka mid ah ayaa roobab ka da'een, haddana waxaan u baahannahay inaan si wanaagsan u qabanno ka hortagga miridhkublock lever gacanta. Xirmada kabaalka waxaa loo isticmaali karaa marar badan, laakiin waxaa lagama maarmaan ah in laga fogaado isticmaalkablock lever gacanta cimilada roobka si loo wanaajiyo nolosha adeeg ee xannibaadda kabaalka oo la joogteeyo waxqabadka adeegsiga xannibaadda lever. U samee shaqada dayactirka kabaalka kor u qaadista cimilada roobka. Waxyaabaha ka mid ahxannibaadda kabaalka is metal, and most of the metal has the defect of rust.
