Dulmarka Tubooyinka Birta Ductile
Ka samaysan birta shubka ah ee sida caadiga ah loo isticmaalo gudbinta biyaha la cabbi karo iyo qaybinta taas oo leh cimri dherer ka badan 100 sano. Tuubada noocaan ah ayaa si toos ah u horumarinaysa birta birta ah ee hore, taas oo ay meesha ka saartay. Ku habboon in dhulka hoostiisa la dhigo khadadka gudbinta muhiimka ah.
