S280GD Galvanized hlau
S280GD galvanized steel yog cov txheej txheem kub-dip galvanized steel nrog qhov tsawg kawg nkaus lub zog ntawm 280MPa. Ua raws li EN 10346, ASTM A653, thiab JIS G3302 tus qauv, peb cov khoom muaj xws li coils, vov tsev vaj huam sib luag, cov khoom siv casings, cov kav dej, thiab kev cai profiles.
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 kev siv hnyav -.

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.
