Galvanized steel phaj nyob rau hauv coil 28 gauge galvanized corrugated steel vov tsev ntawv
piav qhia
Galvanized steel ntawv hais txog cov hlau substrate uas yog galvanized ntawm ob sab ntawm cov ntawv txias-dov hlau, uas tuaj yeem ua ncaj qha rau hauv cov xim pleev xim lossis lwm cov thawv hlau, thiab tseem tuaj yeem siv rau cov khoom siv zoo nkauj.Cov ntawv galvanized yog plated nrog cov xim xim los ua cov xim zinc ntawv.Cov phab ntsa kho kom zoo nkauj feem ntau siv cov ntawv hlau galvanized saum toj 183g / m2, thaum lub ru tsev kho kom zoo nkauj feem ntau siv galvanized hlau ntawv siab tshaj 244g / m2.Tsis tas li ntawd, muaj ib daim ntawv nyias nyias uas tsis muaj lwm yam hlau-coated daim ntaub, qhov loj yog zoo ib yam li cov tin-plated steel ntawv, thiab nws cov yam ntxwv tseem ceeb yog cov yam ntxwv ntawm cov hlau substrate ntawm tin-plated steel ntawv.Hauv kev tsim cov hlau luam ntawv, hom ntawv no yog tsim rau ntau lub cev, lub hau, lub raj mis thermos, thiab cov khoom siv kos npe npog nrog cov xim ntawm ob sab, thiab feem ntau yog siv los ua cov substrate rau coated hlau.
Kev faib tawm
Corrugated steel phaj feem ntau muab faib ua ntau txoj hauv kev raws li qhov chaw thov, qhov siab corrugation, ncej puab thiab cov khoom siv.
Cov txheej txheem kev faib ua feem ntau yog raws li hauv qab no:
(1) Raws li daim ntawv thov, nws muab faib ua vaj huam sib luag ru tsev, phab ntsa vaj huam sib luag, pem teb lawj thiab qab nthab vaj huam sib luag.Hauv kev siv, cov xim hlau phaj kuj tseem siv los ua phab ntsa kho kom zoo nkauj, thiab cov nyhuv kho kom zoo nkauj architectural yog qhov tshiab thiab tshwj xeeb.
(2) Raws li kev faib tawm qhov siab nthwv dej, nws tau muab faib ua cov phaj siab nthwv dej (yoj qhov siab ≥ 70mm), nruab nrab yoj phaj thiab qis yoj phaj (yoj qhov siab<30mm)
(3) Kev faib tawm los ntawm cov khoom siv substrate - muab faib ua kub-dip galvanized substrate, kub-dip galvanized aluminium substrate, thiab kub-dip galvanized aluminium substrate.
(4) Raws li lub rooj tsavxwm seam qauv, nws tau muab faib ua lub puab tsaig sib koom ua ke, undercut thiab tuav cov qauv.Ntawm lawv, qhov nruab nrab thiab siab yoj boards nrog undercut thiab curling yuav tsum tau siv raws li lub ru tsev panels nrog siab waterproof yuav tsum tau: lapped nruab nrab thiab siab nthwv dej galvanized los xij yog siv rau hauv pem teb npog;lapped low wave boards yog siv los ua phab ntsa panels.

Kev faib tawm Galvanized steel phaj yog txhawm rau tiv thaiv qhov saum npoo ntawm cov phaj hlau los ntawm kev corroded thiab ncua nws lub neej kev pab cuam, thiab qhov saum npoo ntawm cov hlau phaj yog plated nrog ib txheej hlau zinc.Raws li kev tsim khoom thiab kev ua haujlwm, nws tuaj yeem muab faib ua pawg hauv qab no: 1. Kub-dip galvanized steel ntawv.Ib daim ntawv hlau yog dipped rau hauv da dej ntawm molten zinc thiab ib daim ntawm zinc yog adhered rau nws nto.Hauv pres...
