Ukucwangciswa kwepleyiti yensimbi kukwamkelwa komphezulu weplate ye-orifice kunye nemijelo, egcina ukwakheka kweempawu zokugcwalisa ngenkcenkceshe yensimbi kunokonyusa ukuthoba kunye nomfaniswano wokugcwaliswa kolwelo, kuphakamise ukusebenza kokuhanjiswa ngobuninzi. Ukucwangciswa kwesinyithi esenziwe ngeMetro ngokupakisha okukhulu, ukumelana okuncinci, izibonelelo zokusebenza kakuhle, ukuxhathisa ukubanakho kokufaka. Ukupakishwa kwepleyiti yensimbi kufumaneka kuluhlu olubanzi lwezixhobo, kubandakanya iinyithi ezingenazintsimbi ezingama-304, 316, 316L, iiCarbonsteels, iAluminiyam, ubhedu lobhedu, njl njl. Ngaba ilungele imichiza, isichumisi, ukucokisa ioyile, ishishini lepetrokhemikhali, igesi yendalo kunye nokunye ukusebenza okuphezulu okupakisha ngokufanelekileyo. Iimpawu: ukubhobhoza okukhulu, ukumelana okuncinci, ukusebenza ngokukuko okuphezulu.
