ASTM A36 Cov Qauv Hlau & Hlau: Tsim, Tsim Khoom Rau Cov Tsev, Cov Tsev Khaws Khoom & Cov Khoom Siv Hauv Paus
Cov Tsev Siab thiab Cov Tsev Lag LuamKev tsim kho vaj tse siab thiab tsev lag luam tau ua rau muaj kev vam meej ntau los ntawm qhov muaj zog, tab sis tsis hnyav, ntawm cov hlau. Qhov no kuj yog vim li cas lawv thiaj li tuaj yeem tsim tau sai thiab vim li cas lawv cov qauv tsim thiaj li hloov pauv tau yooj yim.
Cov Chaw Lag Luam thiab Chaw Khaws Khoom: Cov qauv hlau muab cov chaw khaws khoom, cov chaw ua haujlwm, cov chaw tsim khoom thiab cov khw pwm nrog lawv cov qauv ruaj khov.
Cov Choj thiab Kev Thauj Mus Los: Lub peev xwm thauj khoom siab ntawm cov hlau ua rau nws yog ib qho tseem ceeb uas siv rau hauv kev tsim kho choj, overpasses, flyovers thiab terminals rau kev nyab xeeb thiab kev ruaj khov.
Kev Teeb tsa Hluav Taws Xob thiab Cov Khoom SivCov hlau txhawb nqa cov chaw tsim hluav taws xob, cov chaw ua liaj ua teb cua, cov chaw roj thiab roj av thiab lwm yam kev siv hluav taws xob, nrog rau cov chaw pabcuam, muab kev tiv thaiv ntev tiv thaiv cov huab cua thiab kev qaug zog.
Cov Chaw Ua Si, Kev Lom Zem thiab Kev Nthuav Qhia, Arenas thiab chaw ntau pob, txhua yam ua tau los ntawm qhov tsis muaj cov kem sab hauv uas muaj cov hlau uas tuaj yeem nthuav dav mus deb heev.
Cov Tsev Ua Liaj Ua Teb thiab Chaw Khaws KhoomCov tsev cog khoom ua los ntawm cov hlau, silos, greenhouses, thiab cov tsev cia khoom muaj zog ib yam li lawv tiv taus xeb thiab huab cua.
Kev Tsim Kho Hauv Hiav Txwv, Chaw Nres Nkoj thiab Ntug DejCov qauv hlau zoo tagnrho rau kev tsim kho hauv hiav txwv, tshwj xeeb tshaj yog nyob rau hauv chaw nres nkoj, chaw nres nkoj, piers thiab chaw nres nkoj qhov twg lub zog, kev tiv thaiv corrosion thiab lub peev xwm thauj khoom hnyav tsis sib tham tau.

Ntim:
Cov khoom siv hlau tau ntim zoo rau kev tiv thaiv qhov chaw thiab lawv khaws cov duab ntawm cov khoom thaum lub sijhawm tuav thiab thauj mus los. Feem ntau cov khoom raug qhwv hauv cov ntaub ntawv tsis muaj dej xws li zaj duab xis yas lossis daim ntawv tiv thaiv xeb, thiab cov khoom siv me me yog nyob rau hauv lub thawv ntoo. Thaum sau tag nrho koj tuaj yeem paub tseeb tias koj qhov kev thauj khoom muaj kev nyab xeeb thiab koj qhov kev teeb tsa ntawm qhov chaw yog kev tshaj lij thiab tsis puas tsuaj. Kev ntim khoom zoo tuaj yeem tiv thaiv kev puas tsuaj, kuj tuaj yeem ua rau yooj yim rau kev sau thiab teeb tsa rau cov haujlwm tsim kho.
Kev Thauj Mus Los:
Qhov loj thiab qhov chaw xa khoom yuav txiav txim siab seb cov qauv hlau puas sib nrug sib luag lossis sib tshooj ntawm qhov sib nrug 4 m lossis sib tshooj ntawm cov thawv hlau lossis kev xa khoom ntau. Cov hlua hlau raug ntxiv rau ib puag ncig cov khoom loj lossis hnyav rau kev txhawb nqa thiab cov ntoo so tau muab tso rau ntawm plaub sab ntawm lub ntim khoom kom kaw cov khoom. Txhua txoj kev xa khoom raug ua raws li cov txheej txheem xa khoom thoob ntiaj teb kom xa lawv raws sijhawm thiab muaj kev nyab xeeb txawm tias hla hiav txwv lossis deb heev. Txoj kev ceev faj no ua rau cov hlau raug xa mus rau qhov chaw zoo tshaj plaws rau kev siv tam sim ntawd.
1. Cov Ceg Txawv Tebchaws & Kev Txhawb Nqa Hauv Lus Mev
Peb muaj cov chaw ua haujlwm nyob txawv teb chaws thiab cov neeg ua haujlwm hais lus Mev, peb pab koj sib txuas lus nrog cov neeg siv khoom hauv cov tebchaws Latin America thiab Tebchaws Europe. Peb pab neeg kuj pab koj hauv kev lis kev cai, cov ntaub ntawv thiab cov txheej txheem xa khoom tuaj kom coj kev pabcuam zoo rau koj.
2. Muaj Tshuag rau Kev Xa Khoom Sai
Peb kuj tseem khaws cov khoom siv hlau ua vaj tse ntau heev xws li H-beams, I-beams thiab lwm yam khoom siv ua vaj tse. Qhov no lav tias cov khoom yuav raug xa tuaj sai txawm tias yog cov haujlwm ceev tshaj plaws nrog lub sijhawm ua khoom tsawg kawg nkaus.
3. Kev tshaj lij Ntim Khoom
Tag nrho cov khoom tau ntim khoom kom ruaj ntseg nrog cov pob khoom seaworthy - steel ncej bundling, waterproof wrapping thiab ntug tiv thaiv. Qhov no ua rau kev tuav huv si, kev ruaj khov hauv kev xa khoom mus deb thiab tsis puas tsuaj ntawm chaw nres nkoj mus ncig.

Peb cov kev pabcuam suav nrog FOB, CIF, DDP & lwm yam thiab peb koom tes nrog cov neeg xa khoom hauv tebchaws uas ntseeg tau. Los ntawm hiav txwv, tsheb ciav hlau lossis txoj kev, peb lav qhov kev xa khoom raws sijhawm thiab muab kev taug qab logistics rau koj txhua txoj kev.
Txog cov teeb meem zoo ntawm cov khoom siv
Q: Kev ua raws li cov qauv Cov qauv twg siv tau rau hauv koj cov qauv hlau?
A: Peb cov qauv hlau ua raws li Cov Qauv Asmeskas xws li ASTM A36, ASTM A572 thiab lwm yam piv txwv li: ASTM A36 yog cov qauv carbon dav dav, A588 yog cov qauv siab - huab cua - tiv taus uas tsim nyog siv rau hauv huab cua hnyav.
Q: Koj tswj tau qhov zoo ntawm cov hlau li cas?
A: Cov khoom siv hlau yog los ntawm cov chaw tsim hlau hauv tsev lossis thoob ntiaj teb uas muaj kev tswj hwm zoo. Thaum lawv tuaj txog, cov khoom raug kuaj xyuas kom zoo, suav nrog kev tshuaj xyuas cov tshuaj lom neeg, kev kuaj cov khoom siv kho tshuab thiab kev kuaj tsis puas tsuaj, xws li kev kuaj ultrasonic (UT) thiab kev kuaj cov khoom sib nqus (MPT), los xyuas seb qhov zoo puas ua tau raws li cov qauv cuam tshuam.
