Isakhiwo seSakhelo sePortal yeNsimbi ye-ASTM A572 yeBanga lama-42/50/55/60 seWarehouse kunye neWorkshop
A ukwakhiwa kwesakhelo sentsimbi yesangoluhlobo lwesakhiwo esisetyenziswa kakhulu kwizakhiwo zoshishino, zorhwebo, kunye nezakhiwo zasefama ngenxa yesantya saso, ukulula kunye nokuguquguquka kwaso. Yenziwe ikakhulu ziikholamu ezimbini (amalungu ami nkqo) kunye nomqadi wophahla othe tye okanye othambekileyo (umqadi) odityaniswe ngokuqinileyo kwiindawo ezidibeneyo kwinqanaba, okwenza isakhelo "sesango" esinokumelana namandla asecaleni ngaphandle kwee-bunkers zenkxaso ephakathi yamadoda.
Iindawo zeZakhiwo
Iikholamu — Izinto ezithe nkqo ezithwala umthwalo wophahla.
Iirafters - Iimitha ezithe tyaba okanye ezithe tye ezenza iphimbo lophahla.
Iipleyiti zesiseko kunye neziseko - Qhagamshela iikholamu kwisiseko.
IiPurlins kunye neeGirts: – Izinto zesibini ezixhasa uphahla kunye nezigqubuthelo zodonga.
Ukubambelela (ukhetho) – Yongeza uzinzo olongezelelekileyo ecaleni ukuze uhlale ixesha elide.
Iingenelo: ixesha elide, isantya sokwakhiwa, inkululeko yoyilo, ixabiso eliphantsi.

Sigcina izinto ezaneleyo zokwakha isinyithi esitshisiweyo esisemgangathweni ezifana ne-H beam, i-I beam kunye nezixhobo zesakhiwo sesinyithi.
Oku kuthetha amaxesha okukhawuleza okufumana isibonelelo ukuze abathengi bafumane imveliso abanokuyithemba, ngokukhawuleza, kuloo misebenzi ingxamisekileyo.
3. Ukupakisha kobungcali
Zonke iimveliso zigcwele upakisho oluqhelekileyo olulungele ulwandle (ukubopha isakhelo sentsimbi, ukusonga okungangeni manzi, ukhuseleko lwemiphetho).
Oku kuya kuqinisekisa kwaye kuqinisekise ukulayisha okukhuselekileyo, akukho ntshukumo ngexesha lokuthuthwa komgama omde kwaye akukho monakalo xa ufika kwizibuko eliya kulo.
4. Ukuthunyelwa kunye nokuHanjiswa okuSebenzayo
Sisebenzisana nabathumeli belizwe abathembekileyo kwaye sinokubonelela ngemiqathango yokuhanjiswa eguquguqukayo: FOB, CIF, DDP.
ngolwandle, ngololiwe, ngendlela, sikuthembisa ukuthunyelwa ngexesha elifanelekileyo kunye nenkonzo yokulandelela izinto esebenzayo.
Unyango oluboniswayo kumphezulu: I-Epoxy zinc-rich coating, I-Galvanized (ubungakanani be-hot dip galvanized layer thickness≥85μm bunokufikelela kwiminyaka eli-15-20), i-black oil, njl.njl.
I-Black Oil
I-Galvanised
Ukwaleka okutyebileyo kwe-Epoxy Zinc
Iphakheji:
Ezi mveliso zikhuselekile kakuhle xa zipakishwa ukuze zigcine umphezulu wazo kunye nesakhiwo sazo sicocekile ngexesha lokuphathwa. Ezi nxalenye zihlala zipakishwa ngezinto ezingangeni manzi ezifana neplastiki okanye iphepha elingangeni mhlwa kwaye izixhobo ezincinci zipakishwa ngebhokisi yomthi. Ukongeza, zonke iintambo/iinxalenye ziphawulwe ngokucacileyo ukuqinisekisa ukukhutshwa kwezinto ngokukhuselekileyo kunye nokufakelwa kobuchwephesha kwindawo leyo.
Uthutho:
Izakhiwo zentsimbi zingathunyelwa ngesikhongozeli okanye ngomthwalo omkhulu ngokwesayizi nendawo eziya kuyo. Izinto ezinkulu okanye ezinzima nazo zibotshelelwa ngokuqinileyo ngeentambo zentsimbi ezineentambo zomthi kumacala omabini ukuze zikhuseleke kabini ngexesha lokuthuthwa. Zonke iinkqubo zothutho zenziwa ngokwemigangatho yothutho yamazwe ngamazwe, nokuba ngumgama omde naphesheya kwezilwandle, ukuqinisekisa ukuba iimveliso zihanjiswa ngexesha elifanelekileyo nangokhuseleko.
Q1: Yintoni ipleyiti yentsimbi ye-ASTM A572?
I-A:ASTM Intsimbi ye-A572 yipleyiti yentsimbi yesakhiwo enamandla aphezulu, esezantsi (HSLA) esetyenziswa kakhulu kulwakhiwo. Amanqanaba angama-42, 50, 55, kunye nama-60 abonisa amandla ahlukeneyo amancinci okuvelisa (42K, 50K, 55K, kunye ne-60K ngokwahlukeneyo), enokukhethwa ngokweemfuno zemithwalo eyahlukeneyo.
Umbuzo 2: Yintoni eyenza ukwakhiwa kwesakhelo sesango kufaneke ukusebenzisa i-ASTM A572?
A: IFortaSteel inamandla aphezulu, iyakwazi ukuwelda kakuhle kwaye iyamelana nokugqwala njenge-ASTM A572 efanayo. Ukusetyenziswa kwizakhelo zesango kuzisa inzuzo yeendawo ezinde ezicacileyo kwaye ukusetyenziswa okuncitshisiweyo kwentsimbi kunye nesakhelo sesango kuya kuba ngundoqo ekuqinisekiseni uzinzo lwesakhiwo kwiindawo zokugcina impahla nakwiindawo zokusebenzela.
Q3: Zeziphi izicelo eziqhelekileyo?
A: Ezi freyimu zesango zifumana usetyenziso olubanzi ngolu hlobo:
Iindawo zokugcina impahla kunye neendawo zokugcina izinto zoshishino
Iiworkshops zokwenza nokuvelisa
Izakhiwo zasefama
Ii-hangars zeenqwelo moya kunye namaziko okuthuthwa kwezinto
Q4: Ndingaya kude kangakanani kwaye ndifikelele kwinqanaba elingakanani?
A: Ngokuxhomekeke kwiimfuno zeprojekthi kunye noyilo lwesakhiwo, iifreyimu zesango le-aluminium ezinentsimbi ye-A572 zinokuba nobubanzi obufikelela kwi-10–60 yeemitha (33–197 ft) kunye nokuphakama kobude obufikelela kwi-4–15 yeemitha (13–50 ft).
Umbuzo 5: Ngaba singazenzela ngokwezifiso iifreyimu ngokweemfuno ezizodwa?
A: Ewe. Ubukhulu bekholamu kunye ne-rafter, iindawo zophahla, i-bracing, i-clodding yodonga kunye nophahla inokwenziwa ngokwezifiso ukuze ihambelane nomthwalo, ukususwa kunye neenkcukacha ezibonakalayo zeprojekthi nganye.
Umbuzo 6: Yeyiphi indlela yokukhusela umhlwa?
A: Ngokwesiqhelo nge-hot dip galvanize, i-epoxy coating okanye inkqubo yepeyinti ukuqinisekisa ukusetyenziswa kwexesha elide ngaphakathi nangaphandle.
Umbuzo 7: Ifakelwa njani?
A: Izinto zefreyimu yesango ziyalungiswa kwaye zithunyelwa kwindawo. Ukuhlanganiswa kukudibanisa iintsika kunye neerafu kunye, uze wongeze ii-purlins, ii-girts kunye ne-cladding. Ukwenziwa kwangaphambili kuvumela ukuhlanganiswa ngokukhawuleza kwindawo.
Umbuzo 8: Ziziphi iingenelo zokusebenzisa iifreyimu zesango ze-ASTM A572?
A: Umlinganiselo ophezulu wamandla ukuya kobunzima
