I-H-Beam ye-Carbon Steel ye-Q355/Q355B eyenziwe ngokwezifiso yokwakha i-Bulk Wholesale Wholesale Competitive Price Cutting Ukugoba Iyatholakala
I-Hot Rolled H Beamingxenye evundlile iqukethe iwebhu (isigaba esimaphakathi esiqondile) kanye nama-flange (izingxenye ezivundlile kuzo zombili izinhlangothi). Ama-flange anezindawo zangaphakathi nezangaphandle ezifanayo, futhi ukushintshela kuwebhu kufana ne-arc. Lo mklamo unikeza izinzuzo ezilandelayo:
Amandla aqinile okugobeka: I-modulus yesigaba esiphezulu ikhulisa kakhulu amandla okuthwala umthwalo wemisebe ye-I yendabuko kanye neziteshi ngesisindo esifanayo.
Ukuqina okuphezulu kwesakhiwo: Ububanzi beflange efanayo bunikeza ukuqina okuhle kakhulu ohlangothini, okwenza ifaneleke ukusekela imithwalo yezinhlangothi ezimbili.
Ukusebenza kahle kwezinto ezibonakalayo okuphezulu: Inkinga yokuxineka okuhlobene nezingxenye zensimbi zendabuko iyancipha, okusindisa u-10% kuya ku-30% wensimbi.

Izici
Insimbi Yomqamulo We-Hiyiphrofayili engabizi enomumo wesigaba esiphambene ofana nohlamvu olukhulu lwesiLatini u-h, owaziwa nangokuthi imisebe yensimbi yendawo yonke, imisebe ye-I ebanzi noma imisebe ye-I ehambisanayo. Ingxenye yensimbi enomumo we-H ivame ukufaka izingxenye ezimbili: iwebhu ne-flange, ebizwa nangokuthi ukhalo nomphetho. Ubukhulu bewebhu bensimbi enomumo we-H bungaphansi kobemisebe ye-I evamile enokuphakama kwewebhu okufanayo, kanti ububanzi be-flange bukhulu kunobemisebe ye-I evamile enokuphakama kwewebhu okufanayo, ngakho-ke ibizwa nangokuthi imisebe ye-I ebanzi.
Isicelo
Imisebe ye-H, ngenxa yokusebenza kahle kwazo okuphezulu kanye nokusebenza kahle kwezindleko, sezibe yinto eyinhloko yezakhiwo zensimbi zesimanje futhi zisetshenziswa kabanzi ku:
Ukwakhiwa: Izitshalo zezimboni, ozimele bezakhiwo eziphakeme, kanye nezindawo ezinkulu (njengezikhumulo zezindiza nezinkundla zemidlalo);
Ubunjiniyela bebhuloho: Imishayo emikhulu kanye nezinsika zamabhuloho esitimela kanye nemigwaqo emikhulu, ikakhulukazi izakhiwo zensimbi ezinkulu;
Ukukhiqiza Imishini: Ozimele bemishini esindayo, imishayo ye-crane track, ama-keel emikhumbi, njll.;
Izimboni Zamandla Namakhemikhali: Amapulatifomu ensimbi, imibhoshongo, izinsika, nezinye izikhungo zezimboni.
1. Angakanani amanani akho?
Amanani ethu angashintsha kuye ngokuthi ukunikezwa kwempahla kuyatholakala yini kanye nezinye izici zemakethe. Sizokuthumelela uhlu lwamanani olubuyekeziwe ngemuva kokuxhumana nenkampani yakho.
nathi ukuze uthole ulwazi olwengeziwe.
2. Ingabe unenani elincane kakhulu le-oda?
Yebo, sidinga ukuthi wonke ama-oda aphesheya abe nenani elincane eliqhubekayo le-oda. Uma ufuna ukuthengisa kabusha kodwa ngamanani amancane kakhulu, sincoma ukuthi uhlole iwebhusayithi yethu.
3. Ungakwazi yini ukunikeza amadokhumenti afanele?
Yebo, singanikeza imibhalo eminingi kufaka phakathi Izitifiketi Zokuhlaziya/Ukuhambisana; Umshwalense; Umsuka, kanye neminye imibhalo yokuthumela ngaphandle lapho kudingeka khona.
4. Singakanani isikhathi esimaphakathi sokuhola?
Kumasampula, isikhathi sokuhola cishe siyizinsuku eziyi-7. Ekukhiqizweni ngobuningi, isikhathi sokuhola siyizinsuku ezi-5-20 ngemuva kokuthola inkokhelo yediphozithi. Izikhathi zokuhola ziqala ukusebenza uma
(1) sesiyitholile idiphozithi yakho, futhi (2) sinemvume yakho yokugcina yemikhiqizo yakho. Uma izikhathi zethu zokukhokha zingasebenzi ngesikhathi sakho sokugcina, sicela ubuyekeze izidingo zakho ngokuthengisa kwakho. Kuzo zonke izimo sizozama ukuhlangabezana nezidingo zakho. Ezimweni eziningi siyakwazi ukwenza kanjalo.
5. Yiziphi izinhlobo zezindlela zokukhokha ozamukelayo?
U-30% kusengaphambili nge-T/T, u-70% uzoba ngaphambi kokuthunyelwa okuyisisekelo ku-FOB; u-30% kusengaphambili nge-T/T, u-70% uma kuqhathaniswa nekhophi ye-BL eyisisekelo ku-CIF.
