TS EN 10219 Cov yeeb nkab steel yog ib hom hollow steel seem uas muaj cov kab sib dhos. Nws yog feem ntau siv hauv kev tsim kho, vim nws muaj zog, ruaj khov, thiab tiv taus deformation. Rectangular steel kav yog tshwj xeeb tshaj yog siv nyob rau hauv cov qauv uas yuav tsum tau ib tug muaj zog thiab nruj thav duab, xws li txuas hniav, vaj tse, thiab chaw ntau pob.
Qhov ntev ntawm cov yeeb nkab steel tuaj yeem sib txawv, nyob ntawm seb nws xav siv. Lawv feem ntau ntsuas los ntawm lawv qhov ntev, nrog rau qhov dav, qhov siab, thiab phab ntsa thickness. Cov phab ntsa tuab tuaj yeem nyob ntawm ob peb millimeters mus rau ob peb ntiv tes, nyob ntawm qhov loj thiab lub zog ntawm cov yeeb nkab yuav tsum tau ua.
Rectangular steel kav feem ntau yog tsim los ntawm carbon steel, uas paub txog nws lub zog thiab kav ntev. Txawm li cas los xij, lwm yam khoom siv, xws li cov hlau tsis muaj steel lossis hlau alloy, kuj tuaj yeem siv tau nyob ntawm qhov xav tau siv. Cov kav dej no tuaj yeem yuav ntau qhov ntev thiab qhov ntau thiab tsawg, ua rau lawv haum rau ntau yam kev siv.
Txheej tiv thaiv corrosion
S355J2H kub dov hollow seem steel raj yuav coated anti-corrosive txheej ua ntej xa khoom. Feem ntau, peb cov kua roj vanish rau sab hauv thiab sab nraud ntawm cov khoom siv hlau thaum khaws cia thiab tiv thaiv cov khoom thauj los ntawm kev puas tsuaj thaum thauj. Tsis tas li ntawd, cov kav dej no kuj tuaj yeem ua kub dipped galvanizing.
Kos npe ntawm S355J2H kub dov hollow seem steel raj
Kev kos duab yog pleev xim los yog tawv stenciled ntawm cov yeeb nkab kawg raws li tus qauv thiab cov neeg siv khoom thov. Cov kav hlau hollow me me tuaj yeem muab khi ua ke. Tib cov ntaub ntawv thiab cov ntaub ntawv ntxiv yog qhia rau ntawm cov ntawv cim npe.
Daim ntawv thov ntawm S355J2H kub dov hollow seem steel raj
EN 10210-1 S355J2H cov kav dej muaj txiaj ntsig zoo hauv kev tsim kho ntawm cov chaw xws li cov chaw ua si loj, cov yees rau kev sib kis, kev lag luam ntawm cov tshuaj thiab cov khoom siv hluav taws xob, cov kab tsheb ciav hlau, cov tsev cog khoom ua liaj ua teb, txuas hniav, txoj kev loj railings, steel qauv.
