Big Spangle Galvanized Steel Sheet and Coils Zinc 120g Unoiled Chromated JIS G3302 SGCC

Big Bright Spangle Galvanized Steel Sheet in Coils 

Galvanised steel coils are thin steel sheets that are dipped into molten zinc in order to attach a layer of zinc to the surface. This is an effective method of corrosion protection that extends the life of the metal material.

Main characteristics of galvanised steel

Corrosion protection: 13 years for heavy industrial areas, 50 years for marine, 104 years for suburban areas and 30 years for urban areas.

Spangle Situation 

Regular Spangle

A regular bright pattern produced on hot-dip galvanised steel sheets by adding certain heavy elements to the molten zinc bath.
