S280GD Galvanized hlau
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.
S280GD galvanized steel yog muaj nyob rau hauv peb daim ntawv tseem ceeb ntawm GNEE STEEL: coils, nplooj ntawv, thiab strips. Txhua daim ntawv tsim khoom tsim los ua kom tau raws li cov kev xav tau ntawm kev lag luam, muab ntau qhov ntau thiab tsawg thiab thicknesses haum rau ntau yam kev siv.
Daim ntawv thov
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.
