Kev lag luam tsim kho thoob ntiaj teb tab tom pib ntawm kev loj hlob sai thiab kev thov nce ntxiv rauASTM H-Beamsawv ntawm pem hauv ntej hauv qhov kev hloov pauv tshiab no. Nrog rau qhov xav tau ntau ntxiv rau cov khoom siv muaj zog hauv kev lag luam, kev lag luam thiab kev siv hauv paus, cov neeg muab khoom thoob ntiaj teb ntawm cov khoom zoo li no tab tom tshwm sim - suav nrogRoyal SteelGroup, ib lub tuam txhab xa khoom thoob ntiaj teb uas ua raws li ASTM cov khoom siv hlau.
Kev tshawb fawb txog kev ua lag luam tau tshaj tawm tias qhov kev thov ntawmASTM A992 H BeamthiabASTM A36 H Beamkwv yees tias yuav nce ntxiv tas li nrog 6.5% kev loj hlob txhua xyoo thaum lub sijhawm xyoo 2021-2030, uas yog vim muaj kev nqis peev ntau ntxiv rau cov chaw tsim hluav taws xob, cov chaw xa khoom, thiab cov tsev siab. Cov qauv tsim tshwj xeeb no, ua ntej txiav, I beams nrog lub zog zoo dua, qhov loj me meej, thiab BWG 20 sib xws nrog cov cai thiab cov qauv kev tsim kho thoob ntiaj teb tam sim no yog qhov kev xaiv zoo tshaj plaws rau Engineers thiab Builders ib yam nkaus rau tus nqi thiab kev ua tau zoo.
Cov teb chaws Es Xias Qab Teb - Malaysia, thiab Philippines tshwj xeeb - tab tom muaj kev loj hlob ob npaug hauv kev tsim kho kev lag luam thiab chaw khaws ntaub ntawv, thiab kev xav tau rauH-beamsCov uas tau ntawv pov thawj ASTM muaj zog heev. Latin America Guatemala thiab Panama tab tom tsim lawv cov chaw tsim kho vaj tse thiab chaw nres nkoj, Brazil tab tom nthuav nws cov lag luam hauv kev lag luam hlau thoob ntiaj teb.
Cov kws tshaj lij hauv kev lag luam hais tias qhov kev nyiam nrog ASTM H-beams yog tias lawv tau ua tiav thiab ua raws li tus qauv thoob plaws lub rooj tsavxwm uas ua rau kev nrhiav khoom yooj yim dua thoob ntiaj teb nrog rau kev muab kev ruaj khov ntawm cov qauv. Nrog kev nyuaj siab los ntawm tsoomfwv kom mus rau qhov muaj kev nyab xeeb dua, ntsuab dua thiab ruaj khov dua thaum tsim kho, zoocov hlau ua vaj tse— tshwj xeeb tshaj yog cov H-beams uas tau ntawv pov thawj ASTM — tau teem caij kom txuas ntxiv ua ib qho kev hloov pauv loj thoob ntiaj teb.
Yog li ntawd, cov chaw tsim khoom thiab cov neeg xa khoom tawm uas ua raws li ASTM cov qauv tau muab tso rau pem hauv ntej ntawm cov saw hlau thoob ntiaj teb, ua tau raws li qhov xav tau ntawm lub zog, qhov tseeb, thiab kev ua tau zoo uas txhais tau tias tiam tom ntej ntawm kev tsim kho thoob ntiaj teb.
