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.
