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 daim ntaub ntawv
S280GD yog siv nyob rau hauv ib tug ntau yam ntawm kev tsim kho daim ntawv thov qhov twg siab load- bearing muaj peev xwm thiab ntev - tiv thaiv corrosion yuav tsum tau.
Tej thaj chaw ntawm daim ntawv thov yog
- Ru tsev thiab façade systems: trapezoidal thiab sawv seam profiles rau cov tsev nyob, kev lag luam thiab kev lag luam.
- Cov dej ntws tawm: Gutters, downpipes thiab rainwater collectors.
- Lub teeb yuag steel siv:kev tsim kho hauv tsev, tsev aprons, carports thiab ru tsev.
- Facade cladding:Profiled nplooj ntawv thiab sandwich panels rau phab ntsa thiab qab nthab.
- Hnub ci mounting systems: Ncej thiab substructures nrog lub neej ntev kev pab cuam thiab tsis tshua muaj txij nkawm.
Ua tsaug rau cov kev xaiv hloov pauv tau yooj yim, kev saib xyuas ncua sij hawm tuaj yeem txuas ntxiv thiab tag nrho cov nqi khiav lag luam txo, ua rau S280GD ib qho kev daws teeb meem zoo rau kev tsim kho niaj hnub.

S280GD Hlau 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.
