1.Polish pas nrig yog ib hom tshwj xeeb sucker pas nrig txuas nrog sucker pas nrig thiab beam hanger. Nws yog nyob rau sab saum toj ntawm tus pas nrig, yuav tsum tau dais lub zog tshaj plaws, yog li nrog txoj kab uas hla loj dua thiab qib steel siab dua li tus pas nqus pas, thiab qhov chaw yog du heev.
2.Main muaj nuj nqi:
Ua ke nrog cov khoom ntim rau hauv lub thawv ntim kom kaw lub taub hau thiab tiv thaiv cov roj, roj, dej nthuav tawm.
Interim connector ntawm sucker pas nrig thiab mule taub hau hanger
Finishing indicator diagram test.
Ua kom tiav ntau yam kev ua haujlwm zoo, xws li twj tso kua mis tawm, tswj lub twj tso kua mis.
