S280GD galvanized hlau
S280GD galvanized steel yog muaj nyob rau hauv peb daim ntawv tseem ceeb ntawm GNEE STEEL: coils, nplooj ntawv, thiab strips. Txhua daim ntawv tsim khoom tsim los ua kom tau raws li cov kev xav tau ntawm kev lag luam, muab ntau qhov ntau thiab tsawg thiab thicknesses haum rau ntau yam kev siv.
S280GD impresses nrog sib npaug sib xyaw ua ke ntawm siab zog thiab zoo formability. Qhov tsawg kawg nkaus yield zog Rp0.2 ntawm 280 N / mm² thiab tus yam ntxwv tensile lub zog ntawm yam tsawg kawg nkaus 360 N / mm² kom ntseeg tau tias muaj peev xwm loads - bearing muaj peev xwm txawm nyob rau hauv dynamic load tej yam kev mob. Nyob rau tib lub sijhawm, qhov kub -dip galvanized nto ua rau lub neej ntev kev pab cuam nyob rau hauv ib puag ncig corrosive.

Cov khoom
S280GD impresses nrog sib npaug sib xyaw ua ke ntawm siab zog thiab zoo formability. Qhov tsawg kawg nkaus yield zog Rp0.2 ntawm 280 N / mm² thiab tus yam ntxwv tensile lub zog ntawm yam tsawg kawg nkaus 360 N / mm² kom ntseeg tau tias muaj peev xwm loads - bearing muaj peev xwm txawm nyob rau hauv dynamic load tej yam kev mob. Nyob rau tib lub sijhawm, qhov kub -dip galvanized nto ua rau lub neej ntev kev pab cuam nyob rau hauv ib puag ncig corrosive.
Qhov sib txawv npog variants muaj qhov zoo tshwj xeeb:
+ Z (ntshiab galvanized):
Txuj kev tiv thaiv corrosion rau dav dav.
+ZF (zinc{1}}hlau):
Txhim kho txheej adhesion thiab ua rau muaj zog tiv thaiv kev ntxhov siab.
+ZA (zinc-aluminium):
Optimized kuj nyob rau hauv atmospheric ib puag ncig.
+ZM (zinc{1}}magnesium):
Ntxiv kev tiv thaiv nyob rau hauv maritime thiab saline zones los ntawm passivating cwj pwm.
+ AZ (aluminium-zinc):
Kev sib xyaw ua ke ntawm kev tiv thaiv tshav kub thiab kev tiv thaiv corrosion, zoo tagnrho rau qhov kub thiab txias.
+AS (aluminium-silicon):
Tshwj xeeb tshaj yog rau cov ntawv thov nrog huab cua kub influences thiab siab corrosion loads.
S280GD kuj yog tus cwj pwm los ntawm nws cov weldability zoo, homogeneous microstructure thiab txhim khu kev qha qhov ruaj khov, uas ua kom paub meej ntxiv hauv cov txheej txheem profile, khoov thiab vuam txheej txheem.
