ASTM A36 Steel & Hlau Structures: Tsim, Fabrication rau Tsev, Warehouses & Infrastructure
High-Rise thiab Commercial Buildings: Kev tsim vaj tsev skyscraper thiab kev lag luam tsim tau zoo heev los ntawm qhov muaj zog, tsis tau hnav, xwm txheej ntawm hlau. Qhov no kuj yog vim li cas lawv thiaj li tsim tau sai heev thiab yog vim li cas lawv designs thiaj li hloov tau yooj yim.
Industrial thiab Warehouse Complexes: Cov qauv hlau muab cov tsev khaws khoom, cov chaw ua haujlwm, cov chaw tsim khoom thiab cov khw muag khoom pwm nrog lawv lub zog ruaj khov.
Txuas hniav thiab Thauj Infrastructure: Lub peev xwm thauj khoom siab ntawm cov hlau ua rau nws yog ib qho tseem ceeb uas siv rau hauv engineering txuas hniav, overpasses, flyovers thiab terminals rau kev nyab xeeb thiab kav ntev.
Kev siv hluav taws xob thiab kev siv hluav taws xob: Hlau txhawb nqa fais fab nroj tsuag, cua ua liaj ua teb, roj thiab roj thiab lwm yam kev siv hluav taws xob, nrog rau cov khoom siv hluav taws xob, muab kev tiv thaiv kev ruaj ntseg thiab kev qaug zog.
Kev Ua Si, Lom Zem thiab Exhibition Halls, Arenas thiab chaw ntau pob, yog txhua yam ua tau los ntawm qhov tsis muaj cov kab sab hauv uas them tau los ntawm steel cov khoom siv uas tuaj yeem ncav cuag qhov ntev.
Agricultural thiab Storage Buildings: steel thav duab barns, silos, tsev cog khoom, thiab cov tsev cia khoom yog ruaj khov raws li lawv tiv taus xeb thiab huab cua.
Marine, Chaw nres nkoj thiab Waterfront Infrastructure: Steel ncej yog zoo tagnrho rau kev tsim kho ntawm hiav txwv, tshwj xeeb tshaj yog nyob rau hauv cov chaw nres nkoj, docks, piers thiab harbor complexes qhov twg lub zog, corrosion kuj thiab hnyav loading muaj peev xwm yog tsis-negotiable.

Ntim:
Cov khoom siv hlau tau ntim zoo rau kev tiv thaiv saum npoo thiab lawv khaws cov qauv tsim ntawm cov khoom thaum tuav thiab kev thauj mus los. Cov khoom feem ntau yog qhwv hauv cov ntaub ntawv pov thawj dej xws li yas zaj duab xis lossis daim ntawv tiv thaiv xeb, thiab cov khoom siv me me nyob hauv lub thawv ntoo. Thaum sau tag nrho koj tuaj yeem so kom paub tseeb tias koj qhov kev tshem tawm muaj kev nyab xeeb thiab tias koj lub installation ntawm qhov chaw yog kev tshaj lij thiab tsis muaj kev puas tsuaj. Kev ntim khoom zoo tuaj yeem tiv thaiv kev puas tsuaj, kuj tuaj yeem ua rau cov khoom lag luam yooj yim thiab kev teeb tsa rau lub tsev ua haujlwm.
Kev thauj mus los:
Qhov loj thiab lo lus uas peb txiav txim siab seb cov qauv hlau puas sib npaug los yog qhov sib npaug ntawm qhov hnyav ntawm 4 m ntu lossis crisscrass 2 m intervals steel ntim lossis thauj khoom loj. Cov hlua ntawm cov hlau yog ntxiv nyob ib ncig ntawm cov khoom loj lossis hnyav rau kev txhawb nqa thiab cov ntoo so yog muab tso rau ntawm plaub sab ntawm lub ntim kom kaw lub nra. Tag nrho cov txheej txheem logistics tau ua raws li cov txheej txheem thauj khoom thoob ntiaj teb tau hais kom lawv xa tuaj raws sijhawm thiab ruaj ntseg txawm tias hla hiav txwv lossis mus deb. Qhov kev saib xyuas no ua rau cov hlau xa mus rau qhov chaw ntawm qhov zoo tshaj plaws rau kev siv tam sim.
1. Ceg txawv teb chaws & Txhawb nqa ua lus Mev
Nrog cov chaw ua haujlwm txawv teb chaws thiab cov neeg ua haujlwm hais lus Mev, peb pab txhawb koj kev sib txuas lus nrog cov neeg siv khoom hauv cov tebchaws Latin America thiab Europe. Peb pab neeg kuj txhawb koj hauv kev lis kev cai, cov ntaub ntawv thiab cov txheej txheem ntshuam kom coj tau koj cov kev pabcuam zoo.
2. Muaj Tshuag rau kev xa khoom sai
Peb kuj tseem khaws cov khoom siv hlau ntau ntau hauv cov khoom lag luam xws li H-beams, I-beams thiab lwm yam khoom siv. Qhov no tau lees tias cov khoom xa tuaj nrawm txawm tias cov haujlwm ceev tshaj plaws nrog lub sijhawm ua haujlwm tsawg kawg nkaus.
3. Cov kws tshaj lij Ntim
Tag nrho cov khoom tau ntim ruaj ntseg nrog kev paub txog seaworthy pob - steel ncej bundling, waterproof wrapping thiab ntug kev tiv thaiv. Qhov no ua rau kev tuav huv, ruaj khov hauv kev thauj mus los ntev thiab tsis muaj kev puas tsuaj tuaj txog ntawm qhov chaw nres nkoj hiav txwv.
4. Kev xa khoom sai & xa khoom sai
Peb cov kev pabcuam suav nrog FOB, CIF, DDP & thiab lwm yam thiab peb koom tes nrog cov neeg xa khoom tuaj yeem ntseeg tau. Los ntawm hiav txwv, kev tsheb nqaj hlau lossis txoj kev, peb lav qhov khoom xa tuaj raws sij hawm thiab muab kev pabcuam rau koj taug qab txhua txoj kev.
Hais txog cov teeb meem zoo ntawm cov khoom
Q: Cov qauv ua raws li cov qauv siv hauv koj cov qauv steel yog dab tsi?
A: Peb cov qauv steel ua raws li American Standards xws li ASTM A36, ASTM A572 thiab lwm yam. piv txwv li: ASTM A36 yog ib tug dav lub hom phiaj carbon structural, A588 yog ib tug siab - huab cua - resistanc structural haum rau siv nyob rau hauv cov huab cua hnyav.
Q: Koj tswj qhov zoo ntawm cov hlau li cas?
A: Cov ntaub ntawv hlau yog los ntawm cov neeg paub zoo hauv tsev lossis thoob ntiaj teb steel mills uas muaj kev tswj xyuas nruj. Thaum lawv tuaj txog, cov khoom lag luam raug kuaj nruj me ntsis, suav nrog kev tshuaj xyuas cov tshuaj muaj pes tsawg leeg, cov khoom siv tshuaj ntsuam xyuas thiab cov kev sim tsis muaj kev puas tsuaj, xws li kev kuaj ultrasonic (UT) thiab kev kuaj cov hlau nplaum sib nqus (MPT), los xyuas seb qhov zoo li cas raws li cov qauv muaj feem xyuam.
