Kub dip galvanized hlau
S280GD yog ib qho muaj zog, qis- alloy structural steel uas tau siv dav hauv kev tsim kho thiab tsim khoom. Nrog rau qhov tsawg kawg nkaus tawm lub zog ntawm 280 MPa, nws yog qhov nyuaj txaus rau kev xav tau cov haujlwm ua haujlwm. Qhov kub-dip zinc txheej muab kev tiv thaiv zoo tshaj plaws tiv thaiv corrosion, lav kev ua haujlwm ntev. Ua tsaug rau qhov kev sib xyaw ua ke ntawm lub zog thiab kev tiv thaiv, S280GD yog qhov zoo tshaj plaws rau cov txheej txheem thav duab, vov tsev, thiab lwm yam hnyav - daim ntawv thov.
Lub npe S280GD yog muab los ntawm European tus qauv EN 10346 thiab sawv cev rau:
- S: Cov khoom siv qib steel.
- 280: Yam tsawg kawg nkaus tawm lub zog ntawm 280 MPa.
- GD: Haum rau kev kub kub txuas ntxiv -dip galvanization.
GNEE STEEL muaj S280GD galvanized steel nyob rau hauv ntau hom, nrog rau cov coils, nplooj ntawv, thiab strips. Txhua yam khoom txhawb nqa ntau yam ntawm cov hlau txheej xws li Z275, Z100, thiab AZ150, ua tau raws li cov qauv zoo.
