Kev ua lag luam xav tias yuav loj hlob ntawm qhov nruab nrab ntawm 4.4% thiab ncav cuag US $ 246.3 billion los ntawm 2028.
Reinforceing bars, tseem hu ua rebars, tuaj yeem piav qhia raws li steel tuav lossis hlau mesh siv hauv cov pob zeb thiab cov masonry thiab siv los ua cov tshuab nro.Vim nws tsis tshua muaj zog tensile, nws yuav pab kom stabilize thiab nro pob zeb.Kev tsim kho vaj tse thiab kev tsim kho ntawm kev lag luam siab heev hauv cov teb chaws tsim kho tau nce qhov kev thov rau cov thev naus laus zis tshiab.Hauv kev lag luam steel bar, qhov kev thov rau deformed steel tuav yog siab tshaj.
Piv nrog rau cov khoom siv hlau me me, wrought steel tuav tau paub txog ntau yam khoom zoo nkauj, nrog rau kev ua haujlwm siab thiab ductility, cov txiaj ntsig tseem ceeb ntawm lub zog, durability, zoo heev cuam tshuam thiab corrosion kuj.Tsis tas li ntawd, cov hom no yog kev lag luam thiab yog li nrhiav tau daim ntawv thov hauv kev lag luam, kev lag luam, choj tshuab thiab cov tsev nyob.Lawv cov koob meej kuj tseem loj hlob vim qhov yuav tsum tau ua rau lub zog siab steel installation nyob rau hauv ntau lub tsev tsim.
Kev ua lag luam feem ntau tau txais txiaj ntsig los ntawm kev nce qib hauv kev nqis peev hauv kev tsim kho thiab kev tsim kho vaj tse.Kev siv nyiaj hauv tsoomfwv txhawm rau txhawm rau txhawm rau txhim kho kev tsim kho vaj tse tau ua rau muaj kev loj hlob ntawm kev lag luam thiab txhawb kev lag luam zoo heev.Xyoo 2021, tsoomfwv Suav tau muab yuav luag $ 573 nphom hauv cov nyiaj tshwj xeeb rau kev tsim kho vaj tse.Tsawg kawg yog 50% ntawm tag nrho cov nyiaj tau los ntawm kev tshaj tawm cov ntawv cog lus tshwj xeeb yog qhia rau kev txhim kho kev thauj mus los thiab cov chaw ua si.
Raws li kev siv nyiaj ntau ntxiv rau cov phiaj xwm kho vaj tse, Tebchaws Asmeskas tseem yog cov neeg siv khoom loj thiab tseem yuav tswj hwm ib feem loj ntawm kev lag luam thoob ntiaj teb.Xyoo 2021, tsoomfwv tau tshaj tawm cov kev nqis peev hauv kev lag luam txhawm rau txhawb kev lag luam thiab rov tsim kho vaj tse pej xeem los ntawm kev siv nyiaj ntau yam xws li kev tsheb ciav hlau, txuas hniav, kev sib txuas lus, chaw nres nkoj thiab txoj kev.American Infrastructure Renovation Program tau ua qhov xav tsis thoob rau lub teb chaws txoj kev lag luam rebar.Tsoomfwv Meskas tau hais tias cov choj loj thiab txoj kev loj yuav tsum tau kho.
Nyob rau hauv lub xyoo tom ntej, kev ua lag luam yuav dhau los ntawm qhov tsis muaj cov neeg ua haujlwm txawj ntse thiab tsis tshua muaj kev paub txog cov txiaj ntsig ntawm rebar.Qhov tsis muaj cov ntaub ntawv tsim nyog thiab kev tsis txaus siab siv nyiaj txaus yuav ua rau muaj teeb meem rau lub lag luam thoob ntiaj teb nyob rau xyoo tom ntej.

Kev lag luam steel tau raug cuam tshuam los ntawm COVID-19 qhov tshwm sim.Raws li qhov xwm txheej ntawm tus kabmob kis thoob ntiaj teb, ntau lub tebchaws yuav tsum tau nkag mus rau hauv kev cais tawm kom muaj qhov nce ntawm qhov xwm txheej.Raws li qhov tshwm sim, kev xa khoom thiab kev thov cov saw hlau raug cuam tshuam, cuam tshuam rau kev lag luam thoob ntiaj teb.Vim tias muaj kev sib kis thoob qhov txhia chaw, cov phiaj xwm kev tsim kho vaj tse, cov chaw tsim khoom, kev lag luam thiab ntau lub lag luam yuav tsum raug ncua.
Kev hloov pauv ntawm tus nqi ntawm cov khoom siv raw thiab COVID-19 kev sib kis thoob ntiaj teb tab tom tuav qhov kev loj hlob ntawm kev lag luam thoob ntiaj teb.Ntawm qhov tod tes, txhua yam rov qab mus rau qhov qub, uas txhais tau hais tias kev ua lag luam yuav nce ntxiv rau yav tom ntej.Tsis tas li ntawd, qhov tshwm sim ntawm cov tshuaj tiv thaiv kab mob coronavirus tshiab thiab rov qhib ntau lub chaw rov ua dua tshiab thoob ntiaj teb yuav pom kev lag luam rebar rov qab mus rau tag nrho cov peev txheej.
Qhov sib txawv ntawm rebar muaj nyob rau hauv kev ua lag luam muaj xws li tsis tshua muaj zog rebar, deformed rebar thiab lwm yam rebar (epoxy coated rebar, European rebar thiab stainless hlau rebar).Qhov loj tshaj plaws ntawm kev lag luam thoob ntiaj teb belongs rau ntu deformed, thaum ntu nruab nrab yuav ua qhov thib ob hauv xyoo tom ntej.
Nyob rau hauv cov nqe lus ntawm cov neeg siv kev lag luam kawg, kev lag luam thoob ntiaj teb tuaj yeem pom raws li kev lag luam kev lag luam, kev tsim vaj tsev thiab kev lag luam.
Kev lag luam loj tshaj plaws yog kev tsim kho vaj tse, uas suav txog li 45% ntawm tag nrho cov kev sib koom, thaum kev lag luam kev lag luam suav txog 35% ntawm kev lag luam thoob ntiaj teb.
Raws li kev lag luam loj hlob sai tshaj plaws, thaj av Asia-Pacific kuj yuav dhau los ua tus thawj coj muaj txiaj ntsig thoob ntiaj teb.Lub cheeb tsam muaj kev cuam tshuam zoo rau kev lag luam thoob ntiaj teb vim muaj kev tsim lub teb chaws xws li Nyiv, Kaus Lim Qab Teb, Is Nrias teb thiab Tuam Tshoj, uas yog ib qho ntawm cov chaw tseem ceeb ntawm kev tsim tsheb, vaj tse thiab kev lag luam.Yog li ntawd, qhov kev thov rau steel tuav hauv cov tebchaws no yog qhov tshwj xeeb.Tsis tas li ntawd, kev loj hlob sai ntawm kev lag luam thiab kev lag luam hauv nroog yuav txhawb kev lag luam kev xav tau nyob rau xyoo tom ntej.
North America nyob rau qib thib ob hauv lub ntiaj teb kev lag luam vim tias muaj kev lag luam thiab nroog loj xws li Asmeskas thiab Canada.Hauv cov tebchaws no, kev lag luam tsheb siv cov khoom siv tau tsim.
