S250GD Z275 Galvanized Steel Chev / Sheet Tuam Tshoj tsum

 

Z275 galvanized steel yog kub-dip galvanized steel khoom raws li European Standard EN 10346. Pom tau thoob ntiaj teb raws li qib siab - kev tiv thaiv- qib galvanized khoom, nws muaj lub neej ntev kev pab cuam, ua rau nws nyiam corrosion-cov ntaub ntawv kub ntawm ob qho tib si. cov kab ntau lawm, peb tuaj yeem tsim cov khoom siv galvanized nrog zinc txheej hnyav xws li Z30 txog Z275 g / m². Txuas nrog ntau hom kev ua tshuab, peb tsim cov ntawv tiaj tus galvanized, corrugated ntawv, coil strips, thiab lwm yam ntaub ntawv.

 

S250GD galvanized hlau los ntawmGNEE STEELyog qhov kev xaiv zoo tshaj plaws rau kev tsim kho thiab kev tsim khoom. Nws muaj zog zinc txheej ua kom muaj kev tiv thaiv corrosion thiab kav ntev.

Spangle yog tsim thaum kub -dip galvanizing txheej txheem. Qhov loj, ci ntsa iab, thiab nto ntawm spangles tsuas yog nyob ntawm seb muaj pes tsawg leeg ntawm zinc txheej thiab cov txheej txheem txias. Raws li qhov loj me, nws suav nrog me me spangles, tsis tu ncua spangles, loj spangles, thiab dawb spangles. Lawv saib txawv, tab sis cov spangles yuav luag tsis cuam tshuam qhov zoo ntawm galvanized hlau. Koj tuaj yeem xaiv raws li koj nyiam thiab lub hom phiaj.

Cov khoom siv hlau coated muaj zinc (Z), Galfan zinc-aluminium (ZA), lossis Galvannealed zinc- hlau alloy (ZF) txheej. Kev tiv thaiv cathodic corrosion ntawm cov hlau coatings yog nyob rau hauv ncaj qha kev faib ua feem rau nws thickness, piv txwv li, ib tug tuab txheej yuav muab zoo corrosion tiv thaiv rau lub hauv paus hlau dua ib tug nyias txheej. Txawm li cas los xij, cov txheej nyias nyias raug pom zoo rau cov ntawv thov uas muaj qhov xav tau siab formability.

Zinc

The Zinc (Z) coating has a composition consisting almost entirely of zinc (>99%) thiab yog cov hmoov lead dawb, ua rau cov zinc zoo crystallized spangle uas ua tau raws li qhov xav tau siab rau kev pom kev pom. Nws yog tsim los ntawm kub -dip galvanizing txheej txheem. Ua tsaug rau qhov zoo formability ntawm txhuas- coatings dawb, kev tiv thaiv corrosion, piv txwv li, nyob rau hauv cov cheeb tsam uas tau khoov yog zoo. Lub me me spangle txheej yog tsim los ntawm tsab ntawv M.

Galfan

Galfan (ZA) yog zinc-aluminium alloy txheej nrog eutectic muaj pes tsawg leeg kwv yees li ntawm 95% Zn thiab 5% Al. Cov txheej no muaj kev tiv thaiv zoo dua thiab ua kom zoo dua li cov txheej txheem zinc. Galfan txheej tuaj yeem lees paub los ntawm nws cov xim hlau ci thiab cov cellular me me -patterned nto. Nws yog tsim los ntawm kub -dip txheej txheej txheem.

Galvannealed

Galvannealed (ZF) yog zinc- hlau alloy txheej uas muaj cov ntsiab lus hlau ntawm li 10%. Cov txheej no yog tsim los ntawm tshav kub- kev kho mob tom qab kub tas li- txheej txheej txheej txheej. ZF coated steels yog qhov zoo heev rau kev siv vuam tsis kam thiab yog tsim los siv rau hauv cov khoom zoo siab - pleev xim rau. Galvannealed txheej tuaj yeem lees paub los ntawm nws feem ntau greyish, matte nto.
