BS EN 10210 S355J0H, steel tooj 1.0547, belongs rau cov kub-tsim hollow structural steel seem thiab tuaj yeem ua seamless lossis welded steel yeeb nkab, feem ntau yog siv rau hauv cov qauv uas xav tau lub zog siab thiab zoo toughness, xws li lub tsev loj thiab txuas hniav.
Cov khoom siv S355J0H muaj cov khoom siv kho tshuab uas qhov tsawg kawg nkaus tawm lub zog yog 355MPa thaum phab ntsa tuab tsis tshaj 16 hli thiab ua tau raws li qhov tsawg kawg nkaus cuam tshuam lub zog ntawm 27J ntawm 0 ℃.
BS EN 10210 muaj ntau yam sib txawv ntawm cov duab sib dhos, xws li lub voj voog, square, duab plaub, lossis elliptical, Botop Steel tshwj xeeb hauv cov raj hlau ncig hauv ntau qhov ntau thiab tsawg, muab koj cov khoom zoo thiab cov khoom siv raws li tus qauv steel nrog lub Hoobkas ncaj muag thiab tus nqi sib tw.
Nco tseg: Txhua qhov kev xav tau hauv daim ntawv no kuj tseem siv tau rau EN 10210.
Phab ntsa thickness ≤120mm.
Circular (HFCHS): Sab nraud txoj kab uas hla mus txog 2500 mm;
Square (HFRHS): Sab nraud qhov ntev txog 800 mm x 800 mm;
Rectangular (HFRHS): Sab nraud qhov ntev txog li 750 mm x 500 mm;
Elliptical (HFEHS): Sab nraud qhov ntev txog li 500 mm x 250 mm.

Cov khoom siv hauv BS EN 10210 yog raws li lawv qhov tsawg kawg nkaus tawm lub zog ntawm 16 hli phab ntsa tuab thiab cov khoom cuam tshuam ntawm qhov kub thiab txias.Lub zog tawm los, lub zog tensile, thiab elongation ntawm BS EN 10210 S355J0H txo qis thaum phab ntsa thickness nce.
BS EN 10210 tso cai rau kev tsim khoom siv ntau yam txheej txheem tsim khoom, feem ntau suav nrog seamless, LSAW, SSAW, thiab ERW vuam txheej txheem.
Hauv qab no yog ntau qhov ntau thiab tsawg rau cov txheej txheem ntau lawm.
Los ntawm qhov kev sib piv saum toj no, nws tuaj yeem pom tias cov yeeb nkab tsis muaj seamless steel yeeb nkab muaj qhov muaj txiaj ntsig zoo hauv kev tsim cov yeeb nkab tuab-walled steel yeeb nkab, tshwj xeeb tshaj yog me me-inch tuab-walled steel yeeb nkab, tab sis nws qhov loj me yuav raug txwv.Yog tias koj xav tsim cov kav hlau steel nrog lub cheeb ntawm ntau tshaj 660mm, nws yuav nyuaj dua.
Cov yeeb nkab dub
Qhov no yog hais txog cov yeeb nkab steel yam tsis muaj kev kho deg.
Temporary Protective Txheej
Txhawm rau tiv thaiv kev xeb ntawm cov kav dej steel thaum lub sijhawm khaws cia, kev thauj mus los, lossis kev teeb tsa, ib txoj hauv kev zoo tshaj plaws yog txheej txheej ntawm cov yeeb nkab nrog cov xim pleev xim lossis cov kua roj vanish.
Anti-corrosion Txheej
Muaj ntau ntau hom kev tiv thaiv corrosion, nrog rau cov xim, FBE,3 LPE, thiab galvanized.Txhua hom txheej txheej muaj cov yam ntxwv tshwj xeeb thiab siv tau rau ib puag ncig.Corrosion thiab xeb tuaj yeem tiv thaiv tau zoo los ntawm kev siv cov txheej txheem tiv thaiv corrosion rau cov hlau.
TS EN 10210 Kub dip galvanized txheej ntawm cov yeeb nkab steel yuav tsum ua raws li cov cai ntawm EN ISO 1461.
