Prime Hot Dipped Dx51d Z275 Zinc Coated Galvanized Steel Coil
What kind of steel is galvanized steel?
Galvanized steel is regular steel sheets that have been coated in zinc to make them corrosion resistant. Regular steel is made of iron which will rust when exposed to moisture, either in the form of rain or ambient humidity. Over time rust will corrode a steel part to the point of failure.
