Isixazululo sokuvimbela ukugqwala senqwaba yensimbi eshisayo ye-ASTM A588
Inqubo Yokukhiqiza Inqwaba Yensimbi Egoqekile Eshisayo ye-ASTM A588
I-ASTM A588 Hot Rolled Steel Sheet Pile Locking kanye nokusebenza okungangeni manzi
AseMelika:HDG kuya ku-ASTM A123 (ingubo encane ye-zinc ≥85 µm); ukugqoka okungu-3PE kuyakhethwa; konke ukuqeda kuqinisekiswe yi-RoHS.
INingizimu-mpumalanga ye-Asia: I-hot dip galvanization iwugqinsi (ngaphezu kuka-100μm) futhi kufakwa izendlalelo ezimbili ze-epoxy coating coating tar, ingahlolwa nge-salt spray amahora angu-5000 ngaphandle kokugqwala, okungcono kakhulu ukusetshenziswa ezindaweni zasolwandle ezishisayo.
Umklamo: I-Yin-yang interlock, ukuvuleka kwe-≤1×10⁻⁷ cm/s
AseMelika: Ihambisana nezindinganiso ze-ASTM D5887 zokuvimbela ukuvuza kwamanzi ngaphansi kokushaywa kwezigubhu
INingizimu-mpumalanga ye-Asia: Ivikela amanzi angaphansi komhlaba ezinkathini zemvula zasezindaweni ezishisayo
ISICELO
1. Ubunjiniyela Bezolwandle Nezechweba
Kusetshenziswa ezindongeni zasolwandle, emachwebeni, emachwebeni kanye nasezakhiweni zamachweba lapho kudingeka khona ukumelana nokugqwala okuhlala isikhathi eside.
2. Izisekelo zeBridge & Infrastructure
Isetshenziswa ezindaweni zokuvikela amabhuloho, ukuvikelwa kwemigodi, kanye nokuqina kwesisekelo ukudala ukugcinwa komhlaba okuqinile kanye nokuthwala umthwalo.
3. Ukulawulwa Kwezikhukhula Nokulondolozwa Kwamanzi
Isetshenziswe kakhulu ezindaweni zokuvimba amanzi, ezindaweni zokulwa nezikhukhula, nakwezinye izinhlobo zephrojekthi yokuqinisa imisele ngenxa yamandla ayo amahle kakhulu kanye nokusebenza kwayo okuguquguqukayo.
4. Ukusekelwa Kokumba Ngaphansi Komhlaba Nokumboza
Ingaphakanyiswa yonke ngenhlabathi ukuze kuqiniswe inhlabathi futhi kuvikelwe umsebenzi wezindlu ezingaphansi komhlaba, izindawo zokupaka ezingaphansi komhlaba, iziteshi zesitimela kanye nezindawo zokugcina impahla zesikhashana.
Ukupakishwa Kwezinqwaba Zeshidi Lensimbi
Ukuhlanganisa: Izinqwaba zamashidi ohlobo lwe-U/Z zihlanganiswe ndawonye futhi ziboshwe ngezintambo zensimbi noma zepulasitiki.
Ukuvikelwa Kokuphela: Iziphetho zivikelwe ngezivalo zepulasitiki noma amabhlogo okhuni ukuvikela ekulimaleni ngesikhathi sokuphatha.
Ukulwa nokugqwala: Amaphakheji agcwele iphepha elingangeni manzi elimbozwe uwoyela wokuvimbela ukugqwala noma ifilimu yepulasitiki ehlanganiswe ukuze kufakwe amafasitela.
Ukuthunyelwa Kwezinqwaba Zeshidi Zensimbi
Imodi Yokuthutha: Ngolwandle, ngesitimela noma ngeloli ngokuya ngendawo oya kuyo.
Imigomo Yokulethwa: I-FOB, i-CIF noma i-DDP iyatholakala ngokwewaranti yamakhasimende.
Iyalayisha: Izinqwaba zifakwa kahle esitsheni noma endaweni eyisicaba ukuze zinganyakaziswa futhi zonakaliswe ngesikhathi sokuthuthwa.
Kungani Ukhethe Insimbi Yasebukhosini YaseShayina Yezinqwaba Zeshidi Lensimbi
Insimbi Ephakeme– I-ASTM A588 enamandla aphezulu enokumelana okuhle kakhulu nokugqwala.
Osayizi Abahlukahlukene– Uhlobo lwe-U no-Z, ubukhulu nobude obuningi.

Q4: Ungaletha isikhathi esingakanani?
A: Ngokuvamile izinsuku ezingama-20-35 ngokusekelwe enanini kanye nechweba lokuya kulo.
Q5: Uqinisekisa kanjani ukuthi i-rust ayigqwali?
A: Amaphakheji ezinqwaba asongwa ngephepha elingangeni manzi kanye namafutha avikelwe ukugqwala noma asongwe ngefilimu yepulasitiki.
Umbuzo 6: Ngingayithola kahle imibhalo yokuthumela kwamanye amazwe yokuthengisa?
A: Yebo, kunganikezwa idokhumenti ephelele yokuthumela ngaphandle ehlanganisa uhlu lokupakisha, i-invoyisi yezentengiselwano kanye ne-coa.
