Lub tsev steel yog lub teeb yuag, siab zog, zoo seismic kev ua tau zoo, txuag hluav taws xob, tuaj yeem rov ua lub tsev qauv.Tsim cov khoom tshwj xeeb steel, suav nrog cov khoom siv zoo welded steel, lub zog siab zoo phaj, thermoformed yeeb nkab, steel thiab lwm yam siab solderability;nthuav dav-tsim hlau thiab kub-kuav los tiag H-nqaj ntau yam thiab specifications, nrog rau ib tug loj seem ntawm txias-tsim cov kav dej loj cross-section H-beam thiab lub teeb H-beam, thiab lwm yam;tsim nyog nce qib ntawm kev siv cov weathering steel, refractory steel, Z rau steel thiab cored electrodes thiab hais txog.Qhov txiaj ntsig loj tshaj plaws yog lub peev xwm Steel qauv vaj tse xav kom tib neeg ua haujlwm, xav tau kev xav, thiab kev xav tau nyiaj txiag zoo ua ke.Cov qauv hlau nrog nws tus kheej ua tau zoo tshaj plaws nyob rau xyoo tas los no, kev txhim kho daim ntawv thov sai, daim ntawv thov ntau yuav luag txhua qhov chaw, suav nrog kev tsim vaj tsev, txuas hniav, dams, offshore platforms thiab lwm yam qauv thiab ntauwd mast.

Cov qauv hlau tam sim no siv rau hauv qhov project tuaj yeem ua cov duab sib dhos, cov qauv thiab cov txheej txheem ntau lawm rau kev faib tawm.Xovxwm-section, steel qauv yuav muab faib ua raj qauv (CHS), square (rectangular) zoo li tus tube qauv (RHS) thiab lwm yam zoo li pawg.Vim hais tias ntawm superiority nyob rau hauv cov nqe lus ntawm tsos thiab mechanical kev ua tau zoo, daim ntawv thov ntawm cov yeeb nkab qauv thiab square tube qauv ntawm feem ntau lug siv.Raws li cov qauv hauv daim ntawv ntawm cov ntsiab lus, cov qauv steel tuaj yeem muab faib ua daim phiaj (net plhaub), trusses, thav duab thiab steel yeeb nkab ua vaj tse qauv ntawm plaub.Cov qauv hlau yog hais txog kev siv los ua ib daim ntawv ntawm lub raj thiab lub raj square ntawm cov khoom, cov kav dej thiab cov raj txuas nrog kev sib tshuam welds.Raws li cov txheej txheem ntau lawm rau cov ntsiab lus, cov qauv hlau tuaj yeem muab faib ua cov qauv kub-kuav los tiag steel qauv, txias-dov steel raj qauv, welded steel yeeb nkab qauv peb.Kub-dov steel yeeb nkab phab ntsa thickness yog tuab, siab ntau lawm nqi, txias-dov steel yeeb nkab phab ntsa thickness yog kuj nyias.
