Roj yeeb
Ib tug ntev sawb ntawm cov hlau nrog ib tug hollow seem thiab tsis muaj pob qij txha nyob ib ncig ntawm lub perimeter.
Qhov thib ob pawg ntawm seamless roj steel kav xaj los ntawm peb cov neeg siv khoom qub hauv Iran tau xa tawm hnub no.
Qhov no yog zaum ob rau peb cov neeg siv khoom qub los tso qhov kev txiav txim.Txawm hais tias nws tsis tau qhia peb tias peb cov khoom zoo, nws tus nqi rov qab tau qhia peb txhua yam.
