Fahimci Alama na Zinci a Galvanized Coil

Galvanized coil shine shine na steel wanda aka kuma shi da zinc layer ta hanyar hot-dip ko electro-galvanizing don kare base metal daga corrosion. Thickness na wannan zinc coating, wanda aka maimaita ta hanyar micrometers ko grams per square meter na zinc mass, shine wani abu ne da yawa a cikin specification variables wanda ke soke galvanized coil price. Industry-standard zinc coating grades don hot-dip galvanized coil suna kara daga Z01 zuwa Z05, wanda kowanne yana nufi da zinc deposit mai yawa. Z01 yana ba da lightest coating a cikin 27 grams per square meter per side, wanda ke tsarin indoor applications inda corrosion exposure shine babu. Z05 yana ba da heaviest standard coating a cikin 180 zuwa 275 grams per square meter per side, wanda ke tsarin outdoor structural da marine environments wanda suka nuna maximum corrosion life. Fahimtar wannan coating grades shine wajib saboda kowanne increase a cikin zinc mass yana nufi da direct increase a cikin raw material consumption kuma don haka yana nufi da higher galvanized coil unit cost.
