Hauv kev tsim thiab kev tsim kho, kev siv cov hlau channel (feem ntau hu ua C-section steel) yog qhov ntau heev. Cov channel no yog ua los ntawm cov hlau thiab zoo li tus C, yog li lub npe. Lawv feem ntau siv hauv kev tsim kho kev lag luam thiab muaj ntau yam kev siv. Txhawm rau kom ntseeg tau tias qhov zoo thiab qhov tshwj xeeb ntawm C-section steel raug tswj xyuas, American Society for Testing and Materials (ASTM) tsim cov qauv rau cov khoom no.
ASTM tus qauv rauC-zoo li tus hlauyog hu ua ASTM A36. Cov qauv no suav nrog cov qauv zoo carbon steel cov duab siv rau hauv riveted, bolted los yog welded kev tsim kho ntawm cov choj thiab cov tsev thiab rau cov hom phiaj dav dav. Cov txheej txheem no qhia txog qhov yuav tsum tau muaj rau cov khoom sib xyaw, cov khoom siv kho tshuab thiab lwm yam tseem ceeb ntawm carbon steel C-sections.
Ib qho ntawm cov kev cai tseem ceeb ntawm ASTM A36 tus qauv rauC-channel hlauyog cov tshuaj muaj pes tsawg leeg ntawm cov hlau siv hauv nws cov khoom. Tus qauv xav tau cov hlau siv rau C-sections kom muaj cov qib ntawm cov pa roj carbon, manganese, phosphorus, sulfur thiab tooj liab. Cov kev cai no xyuas kom meej tias cov hlau siv hauv C-channel muaj cov khoom tsim nyog los muab lub zog thiab kav ntev uas yuav tsum tau siv rau kev siv cov qauv.
Ntxiv nrog rau cov tshuaj muaj pes tsawg leeg, ASTM A36 tus qauv kuj tseem qhia txog cov khoom siv ntawm cov hlau siv hauv C-section steel. Qhov no suav nrog cov kev xav tau rau lub zog tawm los, lub zog tensile thiab elongation ntawm cov hlau. Cov khoom no yog ib qho tseem ceeb los xyuas kom meej tias C-channel steel muaj qhov tsim nyog lub zog thiab ductility los tiv thaiv cov loads thiab kev ntxhov siab uas tau ntsib hauv kev tsim kho.
ASTM A36 tus qauv kuj tseem suav nrog qhov ntev ntev thiab qhov ncaj thiab curvature yuav tsum tau rau C-section steel. Cov kev qhia tshwj xeeb no ua kom ntseeg tau tias C-sections uas ua rau tus qauv no ua tau raws li qhov loj thiab cov qauv uas yuav tsum tau muaj rau lawv cov kev npaj siv hauv kev tsim kho.
Zuag qhia tag nrho, ASTM A36 tus qauv rau C-shaped steel muab cov txheej txheem dav dav rau kev ua tau zoo thiab kev ua haujlwm ntawm cov hlau no. Los ntawm kev ua raws li tus qauv no, cov tuam txhab lag luam tuaj yeem ua kom ntseeg tau tias C-sections lawv tsim tau raws li cov lus qhia tshwj xeeb uas xav tau rau kev tsim kho.
Hauv cov ntsiab lus, ASTM tus qauv rauC-channel hlauASTM A36, lub npe hu ua ASTM A36, qhia txog cov kev cai rau cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab qhov ntev ntev ntawm cov hlau no. Los ntawm kev ua tau raws li cov cai no, cov tuam txhab tsim khoom tuaj yeem tsim cov C-sections uas ua tau raws li cov qauv tsim nyog rau ntau yam kev tsim kho. Txawm hais tias nws yog cov txuas hniav, kev siv tshuab lossis cov tsev, ua raws li ASTM C-section steel qauv ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov hlau siv.
