Kev siv ntawm S235JR
S235JR yog tsim rau vuam, bolted kev sib txuas thiab riveting. Nws yog yooj yim weldable thiab khoov thiab haum rau cov qauv tsis tseem ceeb. Nws cov yam ntxwv machinability zoo ib yam li cov hlau me me.
Nws feem ntau yog siv rau hauv kev tsim vaj tsev thiab txuas hniav, cov qauv tsheb, thiab cov cuab yeej thiab cov tshuab txiav. Cov phaj tshwj xeeb yog tsim rau kev tsim cov nkoj.
Kuv BEAMS siv rau dab tsi?
Muaj ntau yam kev siv rau cov kab teeb steel hauv cov qauv steel fabrication. Feem ntau, kuv beams yog siv los ua ib qho tseem ceeb ntawm kev txhawb nqa trusses los yog nyob rau hauv lub moj khaum ntawm lub tsev. Cov kab hluav taws xob steel, feem ntau, yog siv rau hauv daim ntawv thov los muab kev txhawb nqa, vim steel lub zog, durability thiab tsis kam rau xeb (ua tsaug rau cov hlau tiav).
Siv I beams txhais tau hais tias tsawg dua lwm cov qauv kev txhawb nqa uas yuav tsum tau ua, uas yuav pab txuag tau tus nqi thiab sijhawm, thaum tseem ua kom muaj kev ruaj ntseg zoo dua. Universal beams tuaj yeem tswj tau ntau yam kev thauj khoom thaum siv kab rov tav, thiab tib yam tuaj yeem hais tau rau txhua kab thoob plaws raws li kev txhawb nqa ntsug.
HUAB TAIS siv rau dab tsi?
H Beams feem ntau yog siv rau hauv kev tsim vaj tsev ib yam nkaus tab sis kuj muaj cov tsheb loj loj thiab txuas hniav, thiab lwm yam.
Vim lawv cov duab sib txawv me ntsis, lub hauv paus tuab thiab cov flanges dav dua, H beams tuaj yeem nqa cov khoom loj dua li kuv kab. Txawm hais tias ob qho tib si yog cov khoom siv thauj khoom muaj txiaj ntsig zoo, vim tias H beams tuaj yeem ncav cuag ntev npaum li cas, lawv muaj kev ntseeg siab dua rau cov haujlwm loj dua. Txawm li cas los xij, kuv kab teeb yog sib dua thiab tseem muaj pov thawj zoo hauv ntau daim ntawv thov.
