Cov khoom siv hlau feem ntau yuav tsum tau galvanizing, xws liGALVANIZED G40 MIN txheej txheejlos yogGALVANIZED (yuav tsum ua raws li G60 lossis G90 txheej txheej yuav tsum tau ua). Dab tsi yog G40, G60 thiab G90 xa mus rau, thiab dab tsi yog lawv cov galvanized txheej thicknesses? Peb yuav piav qhia lawv raws li hauv qab no:
G40, G60 thiab G90 yog galvanized txheej qib tau teev tseg hauv American ASTM A653 tus qauv. Siv G40 ua piv txwv: G40 txhais tau hais tias tag nrho cov galvanized txheej hnyav ntawm ob sab nce mus txog 0.40 oz / ft², thiab txheej hnyav ntawm ib sab yog 0.12 oz / ft². 1 oz / ft² yog sib npaug rau 1.7 mils, thiab 1 mil sib npaug 25.4μm.

G40:
Zinc txheej hnyav:0.40 oz/ft²(ob leeg ua ke)
Ib -sab sib npaug:0.12 oz/ft²
xam thickness: 0.12 oz / ft2 × 1.7 mils × 25.4 μm =5.18 μm 0.12oz / ft2 × 1.7mils × 25.4μm =5.1816μm
G60:
Zinc txheej hnyav:0.60 oz/ft²(ob tog)
Ib -sab:0.20 oz/ft²
Thickness: 0.20 × 1.7 × 25.4=8.64 μm 0.20 × 1.7 × 25.4=8.636μm
G90:
Zinc txheej hnyav:0.90 oz/ft²(ob tog)
Ib -sab:0.32 oz/ft²
Thickness: 0.32 × 1.7 × 25.4=13.82 μm 0.32 × 1.7 × 25.4=13.8176μm
