12.7mm prestressed steel hlau yog cov khoom siv high-carbon steel hlau tshwj xeeb uas tsim los ua kom tau raws li qhov yuav tsum tau ua ntawm cov pob zeb prestressed.Nws yog tsim los ntawm high carbon steel kub dov hlau pas nrig uas yog cua sov kho thiab txias ua hauj lwm kom tau raws li qhov yuav tsum tau cov khoom.Cov ntsiab lus carbon ntawm cov hlau hlau no yog 0.65% mus rau 0.85%, thiab cov ntsiab lus sulfur thiab phosphorus tsawg, tsawg dua 0.035%.
Lub zog tensile ntawm steel hlau feem ntau yog siab dua 1470MPa, thiab qib zog tau maj mam hloov los ntawm feem ntau 1470MPa thiab 1570MPa rau feem ntau 1670 ~ 1860MPa.Nyob rau hauv cov nqe lus ntawm txoj kab uas hla, steel hlau tau tsim los ntawm ntau tshaj 3 hli mus rau tam sim no ntau yam ntawm 5 mus rau 7 hli.
Los ntawm kev faib cov ntsiab lus ntawm kev pom, 12.7mm prestressed steel hlau belongs rau high-zoo prestressed qhob steel hlau.Nws yog tsim tshwj xeeb los ua kom tau raws li qhov yuav tsum tau ua ntawm prestressed qhob qhov cuab lub zog, muab cov txheej txheem muaj zog thiab ruaj khov rau kev tsim cov haujlwm siv nws.
Saib ntawm cov lus qhia tshwj xeeb, 12.7mm prestressed steel hlau muaj cov ntsiab lus carbon ntawm 0.65% mus rau 0.85%, kom ntseeg tau tias qhov kev ua tau zoo xav tau rau cov khoom siv muaj zog thiab ruaj khov.Nws tseem muaj cov ntsiab lus ntawm sulfur thiab phosphorus qis, ntxiv dag zog rau nws cov kev ua tau zoo.Lub zog tensile ntawm cov hlau yog ntau dua 1470MPa, thiab txoj kab uas hla yog nyob rau hauv thaj tsam ntawm 5 mus rau 7 hli.
12.7mm prestressed steel hlau yog dav siv nyob rau hauv ntau yam kev tsim kho tej yaam num vim nws lub zog tensile siab thiab kev ua tau zoo heev.Nws yog tsuas yog siv nyob rau hauv prestressed pob zeb lug muab kev txhawb zog thiab stability.Txawm hais tias siv rau hauv cov txuas hniav, cov tsev lossis lwm yam kev tsim kho vaj tse, cov hlau hlau no ua kom lub zog muaj zog thiab ua haujlwm ntev ntawm cov qauv uas nws txhawb nqa.Nws versatility thiab kev ntseeg tau ua rau nws yog ib feem tseem ceeb ntawm niaj hnub architecture.
Hauv cov ntsiab lus, 12.7mm prestressed steel hlau yog cov khoom lag luam zoo uas ua tau raws li qhov yuav tsum tau ua ntawm cov pob zeb prestressed.Nws lub zog zoo tshaj, tsis tshua muaj leej faj thiab phosphorus cov ntsiab lus, thiab ntau yam kev qhia tshwj xeeb ua rau nws zoo tagnrho rau ntau yam kev tsim kho.Nrog nws cov keeb kwm ntev thiab kev lees paub thoob ntiaj teb, cov hlau hlau no tau dhau los ua ib feem tseem ceeb ntawm kev tsim kho kev lag luam, ua kom muaj kev ruaj khov thiab ruaj khov ntawm cov qauv thoob ntiaj teb.
Daim ntawv thov
Raws li Tuam Tshoj hlau cov ntaub ntawv kev lag luam ua lag luam, lub teb chaws steel kev lag luam thiab logistics "Pua pua zoo kev lag luam", Tuam Tshoj steel kev lag luam lag luam, "Top 100 private tuam txhab nyob rau hauv Shanghai". ) siv lub "Integrity, Practicality, Innovation, Win-Win" raws li nws txoj kev lag luam ib txwm ua, ib txwm ua siab ntev tso cov neeg siv khoom xav tau thawj qhov chaw.
