Umgangatho wezinto eziphathekayo

Insimbi esetyenzisiweyo iveliswa ngamafektri amakhulu, kwaye izinto ezincedisayo kufuneka zibe kumgangatho ophezulu. Iimfuno eziphambili zezinto ezifunekayo yi-Q235B, iipleyiti zetsimbi eziphakamileyo ezipholileyo, ezikumgangatho ophezulu ezitsalwa ngokubanda ezikhethekileyo zentsimbi okanye imibhobho ye-galvanized (inokukhethwa ngokweemfuno zabathengi abaphezulu kunye ne-anti-rust). ipeyinti.

Umgangatho wemveliso ogqityiweyo

① Iipaliti zentsimbi zenziwe ngokwemizobo yabathengi kunye neemfuno zobugcisa.

②Uqinisekiso lomgangatho: Akusayi kubakho nkunkuma phakathi konyaka omnye phantsi kokusetyenziswa kwesiqhelo.
