Lo mhlahlandlela unikeza ulwazi olujulile mayelana Izikulufi zokhuni zangaphandle zaseChina, ukumboza izinhlobo, izinto zokwakha, izinhlelo zokusebenza, nokucatshangelwa kokukhetha izikulufu ezifanele zamaphrojekthi akho angaphandle. Funda mayelana nokuqina, ukumelana nokugqwala, kanye nezinqubo ezihamba phambili zokufakwa ukuze uqinisekise imiphumela ehlala isikhathi eside. Sizohlola izinketho ezihlukahlukene ezitholakala kubakhiqizi baseShayina futhi sikusize wenze izinqumo zokuthenga unolwazi.
Izinhlobo Zezikulufu Zezinkuni Zangaphandle
Izikulufu Zensimbi Engagqwali
Izikulufi zokhuni zangaphandle zaseChina ezenziwe ngensimbi engagqwali zimelana kakhulu nokugqwala nokugqwala, okuzenza zibe zilungele ukusetshenziswa kwangaphandle. Atholakala ngosayizi abahlukahlukene futhi aqeda ukuze avumelane nezidingo ezahlukene. Amabanga ahlukene ensimbi engagqwali (isb., 304, 316) anikeza amazinga ahlukahlukene okumelana nokugqwala. Amabanga aphezulu, njengo-316, afaneleka kangcono ezindaweni zasolwandle ezinokhahlo. Isibonelo, usayizi ojwayelekile osetshenziswa ekuhlobiseni ngu-6 x 150mm. Ukukhetha ibanga elifanele kubalulekile empilweni ende. Ukuze uthole ulwazi olwengeziwe ngamamaki ensimbi engagqwali kanye nezakhiwo zawo, bheka amazinga emboni afanelekile.
Izikulufu Ezifakwe Ngamanzi Ezishisayo
Amagalani afakwe emanzini ashisayo Izikulufi zokhuni zangaphandle zaseChina nikeza esinye isisombululo esihle kakhulu sokusetshenziswa kwangaphandle. Le nqubo idala i-zinc ewugqinsi enamathelayo ehlinzeka ngokuvikeleka kokugqwala okuphezulu. Lokhu kunamathela kuvikela insimbi engaphansi ekugqwaleni, okuholela ekuphileni okunwetshiwe. Ngokuvamile ziyindlela yokonga kakhulu uma kuqhathaniswa nezikulufu zensimbi engagqwali.
Ezinye Izinto
Nakuba insimbi engagqwali kanye nensimbi ecwilisiwe eshisayo kuyizinto ezivame kakhulu zezikulufu zokhuni zangaphandle, ezinye izinketho zikhona, njengezikulufu ezimboziwe ezinemiphetho eyisipesheli edizayinelwe ukuthuthukisa ukumelana nokugqwala nobuhle. Lezi ziqephu zingabandakanya izimbotshana eziyimpuphu noma ezinye izendlalelo zokuzivikela. Ngaso sonke isikhathi hlola ukucaciswa komkhiqizi ukuze uthole imininingwane yohlobo nokusebenza kwento enamathelayo.
Ukukhetha Izikulufo Ezilungile Zephrojekthi Yakho
Ukukhetha okufanele Izikulufi zokhuni zangaphandle zaseChina kuncike ezintweni eziningana, okuhlanganisa uhlobo lwezinkuni, isicelo, kanye nezimo zemvelo. Cabangela lezi zici ngokucophelela:
Uhlobo Lwezinkuni
Izinkuni eziqinile ngokuvamile zidinga izikulufu eziqinile nezinde kunezinkuni ezithambile. Ukuminyana kokhuni kuzothonya ukukhetha kwesikulufu. Bheka imihlahlandlela yokufaka eqondene nokhuni ukuze uthole imiphumela emihle. Uhlobo lokhuni osebenza nalo luphinde luthinte inani lokumba ngaphambilini ongalidinga.
Isicelo
Izinhlelo zokusebenza ezihlukene zibiza ubude obuhlukene namadayamitha. Amaphrojekthi okuhlobisa angase adinge izikulufu ezinde ukuze kuqinisekiswe ukungena okwanele nokubamba amandla, kuyilapho uthango lungase ludinge izikulufu ezifushane.
Izimo Zemvelo
Ezindaweni ezisogwini noma ezifundeni ezinomswakama ophezulu, insimbi engagqwali noma izikulufi ezifakwe emanzini ashisayo zinconywa kakhulu ngenxa yokumelana kwazo nokugqwala okuphakeme. Ezindaweni ezinokhahlo oluncane, izikulufu ezicwiliswe uthayela ezishisayo zingase zanele.
Lapho Ungathola Khona Izikulufu Zezinkuni Zangaphandle zaseChina
Abakhiqizi abaningi abahlonishwayo e-China bakhiqiza ikhwalithi ephezulu Izikulufi zokhuni zangaphandle zaseChina. Kubalulekile ukukhetha umphakeli onokwethenjelwa ongaqinisekisa ikhwalithi yomkhiqizo nokulethwa ngesikhathi. Ucwaningo olunzulu lubalulekile ngaphambi kokwenza noma yikuphi ukuthenga okubalulekile. Ukuhlola izitifiketi nokuqinisekisa ukubuyekezwa kwabahlinzeki-mpahla kungaba yinzuzo. I-Hebei Muyi Import&Export Trading Co., Ltd iwumthombo onokwethenjelwa wemikhiqizo ehlukahlukene yehadiwe, okuhlanganisa nezikulufu.
Ukufakwa Izindlela Ezinhle Kakhulu
Ukufakwa okufanele kuyisihluthulelo sokuqinisekisa impilo ende nokusebenza kwakho Izikulufi zokhuni zangaphandle zaseChina. Izimbobo zokulinga zangaphambi kokumba zivame ukutuswa ukuvimbela ukuhlukaniswa kwezinkuni, ikakhulukazi ngezinkuni eziqinile. Ukusebenzisa isibhamu esiyisikulufa esinosayizi omncane ofanele kuzoqinisekisa ukufakwa okuhlanzekile nokusebenza kahle. Hlala ulandela izincomo zomkhiqizi zokufakwa.
Ithebula lokuqhathanisa: Insimbi Engagqwali vs. I-Hot-Dipped Galvanized
