Kub-dip galvanized steel
Kub-dip galvanized steel S280GD raws li EN 10346 tus qauv yog siab-cov qauv hlau zoo uas tau tsim tshwj xeeb rau kev siv hauv kev tsim vaj tsev thiab kev tsim vaj tsev. Nrog rau cov khoom siv tooj 1.0244, S280GD muaj qhov tsawg kawg nkaus yield zog Rp0.2 ntawm 280 N / mm² thiab yog li koom nrog cov chav kawm siab zog ntawm galvanized structural steels. Kub-dip galvanizing raws li EN 10346 lav ib txheej zinc txheej ntawm cov hlau nto, uas zoo tiv thaiv cov khoom siv tiv thaiv corrosion. Ua tsaug rau ntau yam txheej txheej txheej txheej (+ Z, + ZF, + ZA, + ZM, + AZ thiab + AS), cov khoom siv tau raug hloov mus rau qhov sib txawv climatic thiab mechanical stresses.
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-dip galvanization.

S280GD Steel Khoom
High Corrosion Resistance:
Cov txheej txheem kub -dip galvanizing tsim cov zinc txheej ruaj khov uas tiv thaiv xeb, ua kom cov hlau tuaj yeem tiv taus cov av noo thiab ntub dej ntev.
Enhanced Structural Stability:
S280GD tuav nws cov kev ua haujlwm zoo raws li ob qho tib si zoo li qub thiab dynamic loads, ua rau nws txhim khu kev qha rau kev thauj khoom -cov kabmob thiab cov qauv dynamic xws li txuas hniav thiab cranes.
Formability zoo heev:
Cov qib steel no tuaj yeem ua tau yooj yim zoo li hauv cov khoom siv xws li cov vov tsev, phab ntsa cladding, thiab cov vaj huam sib luag uas tsis muaj qhov tawg lossis poob qhov zoo.
Muaj zog txheej Adhesion:
Lub zinc txheej yog nruj nreem khi rau cov hlau nto, ua kom ntev - tiv thaiv corrosion txawm tias tom qab txiav, khoov, los yog tsim.
Huab cua Resistance:
S280GD tiv taus ib puag ncig hnav hauv huab cua hnyav, suav nrog kev cuam tshuam ntev los nag, daus, thiab kub hloov pauv, ua kom muaj kev ua tau zoo ib yam dhau sijhawm.
High tshav kub Reflectivity thiab rwb thaiv tsev muaj peev xwm:
Nws qhov saum npoo tuaj yeem cuam tshuam txog qhov tseem ceeb ntawm cov hluav taws xob hluav taws xob, pab tswj kom ruaj khov sab hauv kub hauv cov qauv thiab ua rau nws muaj txiaj ntsig zoo rau lub zog -cov vov tsev zoo lossis rwb thaiv tsev.

- 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.
