Ulwakhiwo lweSakhelo seTruss yeNsimbi ye-ASTM A992 esemgangathweni waseMelika kwiifektri nakwiindawo zokugcina impahla
Ulwakhiwo lweSakhelo seTruss yeNsimbi seSakhiwo seModular Isakhelo setruss yentsimbi luhlobo lwenkqubo yolwakhiwo apho amalungu entsimbi adityaniswe khona ngendlela yeeyunithi ezinxantathu ngokulandelelana okuthile ukwenza isakhelo esiqinileyo esinokusetyenziselwa ukuxhasa imithwalo esetyenzisiweyo. Imilo enxantathu ikhulisa amandla kunye nozinzo ngezinto ezincinci kwaye ifanelekile ixesha elide kunye negumbi elivulekileyo.
Iimpawu ezibalaseleyo
Umlinganiselo Ophezulu Wokuqina-ukuya-Kubunzima -- Ijiyometri yetruss enxantathu ivumela amandla okuthwala umthwalo aqinileyo ngentsimbi encinci.
I-Wide Clear Span - Igubungela indawo ebanzi engenazo iikholamu zangaphakathi.
Uyilo oluneenjongo ezininzi - Lulungele iindawo zokugcina impahla, iiworkshop, izityalo zokuvelisa kunye neeholo kunye neeholo zemidlalo.
Ukwenziwa kwangaphambili kunye nokuhlanganiswa ngokukhawuleza - Iinxalenye zentsimbi zinqunyulwa kwangaphambili kwaye zenziwe ngaphandle kwendawo kwaye zibotshelelwe ngokukhawuleza kwindawo.
Ubude bexesha elide – Xa kusetyenziswa ngokufanelekileyo ukhuseleko lokugqwala (ukugalela i-galvanizing, ukupeyinta, okanye ukugquma), isakhiwo sentsimbi siya kuhlala ixesha elide kangangeminyaka emininzi.

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.

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 intsimbi ye-ASTM A992?
A: I-ASTM A992 ziimpawu ezifanayo nezomeleleyo ze-50 ksi kunye ne-65 ksi ubuncinci bokutsalwa kwentsimbi ye-A572 grade 50, kodwa kunzima kancinci ukuvelisa kuba ziqulathe inqanaba eliphezulu le-silicon kwaye sibone ubunzima ekudibaneni kwayo. Ukudibaneka kwayo okubalaseleyo, ukuqina, kunye neempawu ezifanayo zoomatshini zenza ukuba ibe lukhetho olufanelekileyo kwizakhiwo zentsimbi zorhwebo nezoshishino.
