Kub dip galvanized S320GD
Kub dip galvanized S320GD steel yog siab - lub zog steel. "320" qhia qhov tsawg kawg nkaus tawm lub zog ntawm 320 MPa. S320GD steel yog dav lees paub rau nws zoo heev formability, lub zog, thiab superior corrosion tiv thaiv. Nws tuaj yeem tsim los ntawm kub dov thiab txias dov, nrog rau kev kho kub dip galvanizing. Nws yog dav siv hauv kev lag luam xws li tsheb tsim thiab kev lag luam hauv tsev.
GNEE STEEL muab S320GD nyob rau hauv daim ntawv ntawm coils thiab strips, kom ntseeg tau siab - cov khoom zoo rau ntau yam haujlwm.

Spangle
Lub "spangle" yog ib hom ntawm qhov chaw morphology pom ntawm kub -dip galvanized (ntshiab zinc-coated) steel coils. Thaum cov hlau sawb hla dhau lub lauj kaub zinc, nws qhov chaw yuav coated nrog kua zinc. Raws li zinc txheej ib txwm solidifies, zinc nplej nucleate thiab loj hlob, ua dab tsi hu ua "spangle."
Lub npe "spangle" los ntawm qhov tseeb tias cov zinc ua tiav cov khoom siv ua kom pom cov paj ntoo zoo li cov qauv, uas yog qhov tseeb thiab piav qhia.

FAQ:
S320GD puas tuaj yeem siv rau hauv cov tsev prefabricated?
Yog lawm. Nws yog dav siv nyob rau hauv prefabricated thiab modular siv tshuab vim nws lub zog thiab corrosion kuj.
Dab tsi yog qhov txawv ntawm kub dip galvanized thiab electro-galvanized steel?
Kub dip galvanized steel muaj ib tug tuab, ntau check zinc txheej thiab zoo corrosion kuj zoo li electro-galvanized steel.
Puas yog S320GD galvanized steel haum rau qhov chaw ntub dej?
Yog lawm. Tshwj xeeb tshaj yog nrog Z275 txheej, nws ua tau zoo nyob rau hauv cov av noo thiab nruab nrab corrosive tej yam kev mob.
Dab tsi ntim yog siv rau S320GD galvanized steel coils?
Standard export ntim muaj xws li waterproof wrapping, steel strapping, thiab tiv thaiv ntug thaiv.
S320GD galvanized steel puas tuaj yeem kho tau?
Yog lawm. Thickness, dav, txheej hnyav, nto tiav, thiab coil hnyav tuaj yeem kho raws li qhov xav tau.
