S350GD + Z275 HDG Steel yog dab tsi?

S350GD + Z275 HDG hlauyog lub siab -lub zog kub-dip galvanized (HDG) cov qauv steel qib ua raws li European EN 10346 tus qauv (cov ntaub ntawv tus lej 1.0529), tshwj xeeb yog tsim los rau cov ntawv thov uas xav tau tshwj xeeb corrosion kuj thiab thauj khoom-cov kabmob muaj peev xwm- ua rau nws cov khoom siv hluav taws xob PV, nyiam dua. Lub "S350GD" qhia txog nws cov qauv kev taw qhia thiab qhov tsawg kawg nkaus 350 MPa yield zog, "+Z275" qhia qhov kub kub-dip zinc txheej ntawm 275 g / m² (tag nrho ob sab), thiab "HDG" lees paub qhov kub -dip galvanizing txheej txheem. Nws qhov tshwj xeeb ua ke ntawm lub zog siab, zoo dua corrosion kuj, thiab zoo heev formability hais txog cov ntsiab lus mob ntawm lub hnub ci bracket ua haujlwm -ntev -lub sij hawm sab nraum zoov, hnyav ib puag ncig yaig, thiab cov khoom siv thauj khoom- bearing xav tau -ua rau kev lag luam benchmark rau PV 支枞.

Hnub ci bracketsyog cov tseem ceeb load-cov kabmob ntawm cov khoom siv hluav taws xob photovoltaic, lub luag haujlwm rau kev txhawb nqa hnub ci vaj huam sib luag, tiv taus cua, daus, thiab seismic loads, thiab ua kom ruaj khov rau 25-30 xyoo (lub neej kev pabcuam ntawm PV modules). S350GD + Z275 HDG Steel sawv tawm ntawm cov qauv hlau vim nws cov khoom tsim, zoo kawg nkaus txuam cov kev ua haujlwm ntawm hnub ci brackets. Tsis zoo li cov hlau galvanized zoo tib yam los yog qis- lub zog steel qauv, nws sib npaug lub zog, corrosion kuj, thiab kev ua tau zoo, zam cov teeb meem xws li bracket deformation, txheej txheej tev, thiab xeb ntxov ntxov uas plague qis - cov ntaub ntawv qib.

S350GD + Z275 HDG Steel yog ib qho tshwj xeeb kub-dip galvanized structural steel, nrog rau txhua feem ntawm nws cov npe xa cov ntaub ntawv tseem ceeb ntawm nws cov kev ua tau zoo thiab kev ua haujlwm:

S: Stands rau "Structural Steel", qhia txog nws qhov kev siv tseem ceeb hauv kev thauj khoom -cov kabmob cov khoom siv (xws li hnub ci brackets, lub tsev thav duab, thiab cov khoom siv tshuab).

350: Sawv cev rau qhov tsawg kawg nkaus lub zog ntawm 350 MPa (rau thickness Tsawg dua los yog sib npaug li 3.0mm), txhais tau tias cov hlau tuaj yeem tiv taus qhov tsawg kawg nkaus ntawm 350 megapascals ntawm kev ntxhov siab ua ntej deformation mus tas li - tseem ceeb rau kev txhawb nqa hnub ci vaj huam sib luag thiab tiv thaiv ib puag ncig.

GD: Qhia txog "Galvanized Structural Grade", lees paub tias nws haum rau kub-dip galvanizing thiab kev siv cov qauv, nrog rau microstructure optimized rau lub zog thiab formability.

+Z275: Qhia txog zinc txheej specification: "+Z" txhais tau tias kub-dip ntshiab zinc txheej, thiab "275" yog hais txog tag nrho zinc txheej hnyav ntawm 275 g / m² (kwv yees 137.5 g / m² ib sab){5}} ze li ob npaug ntawm cov txheej txheem Z140 txheej, muab kev tiv thaiv corrosion zoo dua.

HDG: Luv luv rau "Kub-Dip Galvanizing", txheej txheem ntawm immersing cov hlau nyob rau hauv molten zinc los ua ib tug ntom, adherent zinc txheej uas ua raws li ib tug barrier tiv thaiv corrosion- ib qho tseem ceeb feature rau sab nraum zoov hnub ci bracket daim ntaub ntawv.

Ua raws li EN 10346 tus qauv, S350GD + Z275 HDG Steel yog tsim los ntawm kev tswj dov thiab kub -dip galvanizing, kom ntseeg tau tias cov khoom siv sib xws thiab txheej txheej adhesion. Nws cov khoom siv tus lej (1.0529) yog tus cim thoob ntiaj teb rau kev yuav khoom thoob ntiaj teb thiab kev kuaj xyuas zoo, ua rau nws yooj yim rau qhov chaw rau cov haujlwm hnub ci thoob ntiaj teb.

Cov khoom ntawm S350GD + Z275 HDG Steel yog qhov zoo tshaj plaws kom ua tau raws li cov kev cai tshwj xeeb ntawm lub hnub ci brackets, uas ua haujlwm nyob rau hauv qhov chaw sab nraum zoov (tshwj xeeb rau hnub ci, nag, daus, ntsev tsuag, thiab kub hloov pauv) tau ntau xyoo. Hauv qab no yog cov khoom tseem ceeb uas ua rau nws zoo tagnrho rau kev siv PV:

2.1 Mechanical Properties (EN 10346, Ntev)

Hnub ci brackets yuav tsum muaj lub zog muaj zog los txhawb qhov hnyav ntawm lub hnub ci vaj huam sib luag (feem ntau 15-25 kg / m²) thiab tiv thaiv cua loads (txog 1.5 kN / m² rau ru tsev PV) thiab daus loads (txog 2.5 kN / m² rau hauv av- mounted PV). S350GD + Z275 HDG Steel's mechanical zog ua tau raws li cov kev xav tau no:

2.2 Corrosion Resistance (Z275 Txheej Advantage)

Kev tiv thaiv corrosion yog cov cuab yeej tseem ceeb tshaj plaws rau hnub ci brackets, vim lawv raug rau sab nraum zoov ib puag ncig rau 25-30 xyoo. Z275 kub-dip zinc txheej ntawm S350GD + Z275 HDG Steel muab ob txoj kev tiv thaiv corrosion, hais txog qhov mob tseem ceeb ntawm qhov tsis ua haujlwm ntxov ntxov:

Kev Tiv Thaiv Barrier: Cov txheej zinc ntom ntom (275 g / m²) ua rau lub cev tsis muaj zog, thaiv cov pa oxygen, noo noo, thiab cov khoom corrosive (xws li tshuaj tsuag ntsev hauv cov ntug dej hiav txwv, cov kua qaub nag hauv thaj chaw muaj kev lag luam) los ntawm kev ncav cuag cov hlau substrate.

Kev tiv thaiv Cathodic: Txawm hais tias cov txheej txheej raug khawb thaum lub sijhawm teeb tsa lossis siv, zinc (ntau dua reactive dua hlau) ua raws li anode, corroding ua ntej los tiv thaiv cov hlau hauv qab- tiv thaiv xeb hauv thaj chaw puas thiab txuas lub neej kev pab cuam.

Kuaj-Verified Durability: S350GD + Z275 HDG Steel raug kuaj nruj nruj: nws tiv taus xeb liab rau ntau dua lossis sib npaug rau 1,200 teev hauv qhov ntsuas nruab nrab ntsev ntsev (5% NaCl tov, 35 degree) thiab dhau 200 lub voj voog kev xeb (sib npaug rau 10 xyoo ntawm kev siv ntug dej hiav txwv). Kev ntsuam xyuas hauv thaj chaw ntug dej hiav txwv qhia tias cov txheej poob qis dua lossis sib npaug li 30 g / m² tom qab 2 xyoos raug, tsis muaj xeb liab.

Service Life Alignment: Z275 txheej ua kom muaj kev tiv thaiv corrosion- tiv taus lub neej kev pab cuam ntawm 15-25 xyoo, sib piv rau 25-30- xyoo kev pab cuam lub neej ntawm hnub ci modules-tso tawm qhov xav tau kev hloov pauv thiab txo cov nqi kho.

2.3 Fabrication Properties

Hnub ci brackets feem ntau yog tsim rau hauv C-zoo li tus, Z-zoo li tus, los yog U-zoo li tus profiles ntawm txias dabtsi yog khoov, stamping, thiab vuam-yuav tsum tau cov hlau kom muaj zoo formability thiab weldability:
