Kub-dip galvanized steel qauv
Xav tau S350GD Galvanized Steel nplooj ntawv ceev rau koj qhov kev tsim kho? GNEE STEEL khaws ntau tshaj 30,000 tons ntawm S350GD Tshuag hauv peb lub tsev khaws khoom, nrog cov zinc txheej ntau ntawm 60g / ㎡ txog 275g / ㎡. Peb lav cov khoom xa tuaj tsis pub dhau 5 hnub thiab siv seaworthy ntim los tiv thaiv koj cov khoom thauj thaum caij tsheb thauj mus los.
S350gd yog qib hauv European tus qauv "EN 10346-2009 Nruam Kub-Dip Galvanized Steel Sheet Khoom", uas yog cov ntawv hlau galvanized. S350G yog cov qauv hlau uas xav tau lub zog tensile ntau dua 350MPa, D txhais tau hais tias cov ntawv galvanized, yog li s350gd yog cov qauv galvanized ntawv nrog cov khoom muaj zog ntau dua 350MPa.
S350G yog muaj nyob rau hauv cov nram qab no kub dip coatings: S350GD + Z (galvanized), S350GD + ZF (galvanized- hlau), S350GD + ZA (galvanized- txhuas), S350GD + AZ (aluminium{{11}5}zinc), S3 silicon).
Galvanized steel ntawv
cov ntawv thov kev lag luam
Ua tsaug rau nws lub zog siab thiab txhim khu kev tiv thaiv corrosion, S350GD yog siv rau hauv ntau daim ntawv thov kev tsim kho:
Load-cov kabmob steel qauv:Ncej, kab thiab kab teeb nyob rau hauv Hall, choj thiab Hall apron siv.
Ru tsev thiab façade systems:trapezoidal thiab sawv seam profiles rau cov tsev lag luam thiab kev lag luam nrog huab cua tsis kam.
Cov kua dej system:gutters, downpipes thiab rainwater chims uas nyob ruaj txawm nyob rau hauv qab ntsev los yog hauv nroog ib puag ncig.
Hnub ci mounting systems:Substructures rau photovoltaic thiab hnub ci thermal daim ntaub ntawv uas tsis tshua muaj txij nkawm thiab siab load- yuav tsum muaj peev xwm bearing.
Sandwich thiab composite panels:Phab ntsa thiab qab nthab cov ntsiab lus rau kev lag luam hauv tsev thiab chaw logistics uas yuav tsum tau muaj kev nruj nruj thiab ua haujlwm ntev.
Qhov ntau ntawm cov txheej txheem sib txawv tso cai rau kev saib xyuas lub voj voog kom txuas ntxiv thiab cov nqi ntawm lub neej yuav raug txo.
Tshuaj muaj pes tsawg leeg
| Element (Symbol thiab lub npe) | Qhov feem pua (%) |
|---|---|
| Fe (Hlau) | Tshuav |
| C (Carbon) | 0.06 - 0.12 |
| Zn (zeeg) | 0.5 - 1.5 |
| Manganese (Mn) | 0.3 - 0.8 |
| P (phosphorus) | Tsawg dua lossis sib npaug li 0.04 |
| S (Sulfur) | Tsawg dua los yog sib npaug li 0.03 |
Thawj cov ntsiab lus alloying hauv S350GD steel ua lub luag haujlwm tseem ceeb:
- Zinc (Zn):Muab corrosion kuj los ntawm galvanization.
- Cov pa roj carbon (C):Txhim kho lub zog tab sis yuav tsum tau khaws cia qis kom tswj tau qhov ductility.
- Manganese (Mn):Txhim kho hardenability thiab lub zog.

Cov khoom siv hluav taws xob ntawm S350GD steel ua rau nws tsim nyog rau kev siv cov txheej txheem uas lub zog thiab kev ua haujlwm tseem ceeb. Nws lub zog tawm los ntawm 350 MPa ua kom nws tuaj yeem tiv taus qhov hnyav, thaum nws qhov feem pua elongation qhia tau zoo formability.
Nrog rau kev kho dua tshiab ntawm kev xav tau thoob ntiaj teb kev tsim kho, kev lag luam daim ntawv thov scenarios ntawm S350GD galvanized steel txuas ntxiv nthuav dav. Peb tsis tsuas yog muab siab - cov ntaub ntawv zoo uas ua tau raws li cov qauv thoob ntiaj teb, tab sis kuj muab tag nrho - kev daws teeb meem los ntawm kev xaiv cov khoom mus rau kev ua haujlwm.Tiv tauj peb tam sim no thiab cia S350GD galvanized steel yog ib tus khub ruaj khov rau koj txoj haujlwm ua tiav.
