Kev tsim kho thiab kev tsim kho vaj tse txuas ntxiv vam khom rau cov hlau galvanized vim nws cov kav ntev, lub zog, thiab cov nqi ua haujlwm. Ntawm cov txheej txheem txheej txheem teev tseg hauv EN 10346,S250GD + Z galvanized steel ntawvstands raws li ib tug tswv yim thiab dav siv tshuaj. GNEE STEEL muab S250GD + Z galvanized steel nplooj ntawv rau cov haujlwm uas xav tau kev ua haujlwm zoo thiab kev tiv thaiv corrosion.
S250GD + Z yog cais raws li cov txheej txheem zoo steel nrog qhov tsawg kawg nkaus tawm lub zog ntawm 250 MPa. Qhov no ua rau nws tsim nyog rau kev thauj khoom-cov ntaub ntawv bearing thaum tuav cov tsim tsim nyog thiab kev tsim muaj peev xwm.Txawm li cas los xij, tsis zoo li kos duab- zoo galvanized steel, S250GD + Z tseem ceeb rau lub zog thiab ruaj khov. Nws ua tau zoo nyob rau hauv ob qho tib si loads zoo li qub thiab ntev - cov kev pab cuam lub sij hawm.
| Mechanical Property | Tus nqi |
|---|---|
| Yield zog | Ntau dua lossis sib npaug li 250 MPa |
| Tensile zog | 330-410 MPa |
| Elongation | Ntau dua lossis sib npaug li 19% |
| Txuj | TS EN 10346 |
Cov yam ntxwv no ua rau S250GD + Z galvanized steel ntawv haum rau khoov, vuam, thiab sib dhos yam tsis muaj kev cuam tshuam cov npoo kev nyab xeeb.
S250GD + Z galvanized steel los xij yog feem ntau muab nrog zinc txheej hnyav dua kom ntseeg tau ntev -lub sij hawm tiv thaiv corrosion nyob rau hauv ib puag ncig sab nraum zoov.
| Zinc Txheej | Hom kev siv |
|---|---|
| Z180 | Kev tsim kho dav dav |
| Z275 | High humidity los yog sab nraum zoov raug |
Qhov kub dip galvanized txheej tau txuas ntxiv lub neej kev pab cuam thiab txo cov kev xav tau ntawm kev saib xyuas, tshwj xeeb tshaj yog nyob rau hauv vov tsev, laj kab, thiab kev siv cov txheej txheem.
S250GD + Z galvanized steel los xij yog siv dav hauv cov qauv steel, purlins, phab ntsa panels, cable tais, cov tsev ua liaj ua teb, thiab lub teeb steel framing systems. Kev loj hlob ntawm lub hnub ci mounting cov qauv thiab cov tsev prefabricated tau ntxiv kev thov rau qib no.
GNEE STEELUa kom cov khoom siv zoo ib yam, raug zinc txheej tswj, thiab kev ua haujlwm zoo rau txhua pawg ntawm S250GD + Z nplooj ntawv. Nrog kev paub txog kev xa tawm, peb txhawb cov neeg siv khoom nrog cov sijhawm ua haujlwm txhim khu kev qha thiab kev pabcuam.
Tshaj li S250GD+Z, GNEE STEEL muaj ntau dua - qib zog xws li S280GD + Z thiab S350GD + Z, nrog rau DX54D + Z rau kev tsim cov ntawv thov thiab cov khoom PPGI. Cov khoom lag luam tiav no tso cai rau cov neeg siv khoom los tsim ntau yam kev daws teeb meem steel los ntawm ib tus neeg muag khoom ntseeg siab.
