Isakhiwo Sensimbi se-ASTM A913 | Insimbi ye-H-Beam enamandla aphezulu yezakhiwo zezimboni nezentengiselwano
Isakhiwo Sohlaka Lwesivikelo Sensimbi Sokwakha Okunesimo Esifanayo Uhlaka lwesivikelo sensimbi luhlobo lwesistimu yesakhiwo lapho amalungu ensimbi axhunywa khona ndawonye ngesimo samayunithi angunxantathu ngokulandelana okuthile ukuze kwenziwe uhlaka oluqinile olungasetshenziswa ukusekela imithwalo esetshenzisiwe. Ukuma kwesivikelo kukhuphula amandla nokuzinza ngezinto ezincane futhi kufanelekile isikhathi eside kanye negumbi elivulekile.
Izici Ezivelele
Isilinganiso Esiphezulu Samandla-kuya-Esisindweni -- I-geometry ye-truss engunxantathu ivumela amandla okuthwala umthwalo aqinile ngensimbi encane.
Isikhala Esicacile Esibanzi - Simboza indawo ebanzi engenazo izinsika zangaphakathi.
Umklamo wezinhloso eziningi - Kuhle ezindaweni zokugcina impahla, ama-workshop, izimboni zokukhiqiza kanye nama-auditorium namahholo ezemidlalo.
Ukwakhiwa Kwangaphambili Nokuhlanganiswa Okusheshayo - Izingxenye zensimbi ziyasikwa kusengaphambili futhi zakheke ngaphandle kwendawo bese zihlanganiswa ngokushesha endaweni.
Ubude Besikhathi - Uma kusetshenziswa ngokwanele ukuvikela ukugqwala (ukugalela nge-galvanizing, ukupenda, noma ukumboza), isakhiwo sensimbi sizoba nesikhathi sokusebenza amashumi eminyaka amaningi.
Izingxenye

1. Ukusekelwa Kwegatsha Laphesheya kanye Nolimi LwesiSpanishi
Sinehhovisi lakwamanye amazwe elinabasebenzi abakhuluma iSpanishi futhi singakhuluma izilimi ezimbili namakhasimende ethu avela eLatin America naseYurophu.
Ithimba lethu lenza kube lula ukusulwa kwempahla yamasiko, imibhalo, kanye nezidingo zokuthumela kwamanye amazwe ukuze kube lula ukulethwa ngesikhathi futhi kusheshiswe ukucutshungulwa kokungenisa impahla.
2. Isitoko Esilungele Ukulethwa Okusheshayo
Sigcina amasheya anele ezinto zokusetshenziswa zesakhiwo sensimbi esigoqiwe esishisayo njenge-H beam, i-I beam kanye nezingxenye zesakhiwo sensimbi.
Lokhu kusho izikhathi zokuhola ezisheshayo ukuze amakhasimende akwazi ukuthola umkhiqizo angawuthemba, ngokushesha, kuleyo misebenzi ephuthumayo.
3. Ukupakisha kobungcweti
Yonke imikhiqizo igcwele ukupakishwa okujwayelekile okufanele ulwandle (ukugoqa uhlaka lwensimbi, ukugoqa okungangeni manzi, ukuvikelwa kwemiphetho).
Lokhu kuzoqinisekisa futhi kuqinisekise ukulayisha okuphephile, akukho ukunyakaza ngesikhathi sokuthuthwa ibanga elide futhi akukho monakalo lapho ufika echwebeni oya kulo.
4. Ukuthunyelwa Nokulethwa Okusebenzayo
Sisebenzisana nabathumeli bezwe abathembekile futhi singanikeza imigomo yokulethwa eguquguqukayo: i-FOB, i-CIF, i-DDP.
ngolwandle, ngesitimela, ngomgwaqo, sithembisa ukuthunyelwa ngesikhathi esifanele kanye nensizakalo yokulandelela izinto esebenzayo.
Ukwelashwa embukisweni wobuso: Isembozo esicebile nge-zinc, I-Galvanised (ubukhulu besendlalelo esishisayo esifakwe i-galvanised≥85μm bungafinyelela eminyakeni eyi-15-20), i-oyili emnyama, njll.
Okunamafutha Amnyama
I-Galvanised
Isimbozo Esicebile Nge-Epoxy Zinc
Iphakheji:
Imikhiqizo ivikelwe kahle ekupakishweni ukuze igcine ubuso bayo kanye nesakhiwo sayo siphelele ngesikhathi sokuphathwa. Izingxenye zivame ukupakishwa ngezinto ezingangeni manzi njengefilimu yepulasitiki noma iphepha elingagqwali kanti izesekeli ezincane zipakishwa ngebhokisi lokhuni. Ngaphezu kwalokho, zonke izintambo/izingxenye ziphawulwe ngokucacile ukuqinisekisa ukuthululwa okuphephile nokufakwa kobungcweti endaweni.
Ezokuthutha:
Izakhiwo zensimbi zingathunyelwa ngesitsha noma ngesithwali esikhulu ngokuya ngobukhulu nendawo oya kuyo. Izinto ezinkulu noma ezisindayo nazo ziboshelwa ngokuqinile ngamabhande ensimbi anemichilo yokhuni ezinhlangothini zombili ukuze kuvikelwe kabili ngesikhathi sokuthuthwa. Zonke izinqubo zokuthutha zenziwa ngokuya ngezindinganiso zokuhamba zomhlaba wonke, ngisho nebanga elide naphesheya kwezilwandle, ukuqinisekisa ukuthi imikhiqizo ilethwa ngesikhathi nangokuphepha.
