S280GD Steel yog dab tsi?
S280GD yog cov hlau tsis yog- alloy structural steel, ua los ntawm 98-99% hlau thiab 0.1-0.2% carbon, ntsib EN 10346 nrog qhov tsawg kawg nkaus yield zog ntawm 280 MPa. Nws yog ib lub tiaj- dov steel, feem ntau kub-dip galvanized rau corrosion kuj. Hauv S280GD, "S" qhia txog cov qauv hlau, "280" lub zog tawm los, thiab "GD" galvanization. Nws los nrog kev ua tiav zoo li + Z (zinc) thiab + ZF (zinc-hlau), haum rau kev tsim kho, tsheb, thiab lub teeb engineering. Zoo ib yam li FeE280G, nws muaj EU steel tooj ntawm 1.0244.

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.
