Product Description

GI Coil, or Galvanized Iron Coil, refers to steel coils that have been coated with a layer of zinc through the process of galvanization. This coating provides the steel with enhanced corrosion resistance and durability, making it suitable for a wide range of applications.
 

Characteristics

Corrosion Resistance: The zinc coating acts as a sacrificial anode, corroding preferentially and protecting the underlying steel from oxidation.
 

Durability: The zinc layer provides long-lasting protection, with a lifespan that can range from several years to several decades, depending on the thickness of the zinc coating and the environmental conditions.
 

Aesthetic Appeal: The galvanized surface has a distinctive silver-gray appearance, which can be left as-is or further treated with paint or other coatings for additional protection and aesthetic enhancement.
