Zinc Coated Steel Coil
Zinc Coated Steel Coil is extensively used in different fields and applications. You can see it in metal roofing panels, microwave ovens, decorative panels of cars, telecommunication cables and so on.
Composition of Galvanized Steel Coil:
The primary component of galvanized steel coil is, of course, steel. However, the defining characteristic lies in the zinc coating that encapsulates the steel substrate. This zinc layer serves as a sacrificial barrier, corroding in place of the steel when exposed to corrosive elements. Additionally, the thickness of the zinc coating can vary, influencing the level of corrosion protection provided.
Manufacturing of galvanized steel coils:
The manufacturing process of galvanized steel coil is a testament to the intricate fusion of science and industry. Each step, from surface preparation to the application of the zinc coating, contributes to the creation of a material renowned for its corrosion resistance, durability, and versatility. As galvanized steel coil continues to serve diverse industries such as construction, automotive, and manufacturing, its manufacturing process remains a cornerstone of modern materials engineering.

Galvanized steel coil and sheet packaging and transportation:
Benefits include:
Corrosion and rust resistance: The main advantage of zinc coated steel coil is its anti-corrosion and anti-rust properties. The iron element in steel is a highly reactive chemical, prone to rusting. but the addition of zinc plays a role of protective buffer between the steel and moisture or oxygen. So the zinc coating acts as a barrier to resist external attacks, and will sacrifice itself to protect the underlying steel.
Life expectancy: With galvanization, the life expectancy of GI coil is far in excess of 50 years in working environments, and it can last over 20 years with severe water exposure.
Cost: Firstly, galvanizing is a lower overall cost compared to other coatings. In addition, galvanized steel coil can be applied at any time when delivered. It does not require additional preparation for the surface, inspections, painting or coatings.
Durability and reliability: Galvanized steel often uses hot rolled or cold rolled steel coil as base metal. The strength of steel is high and the zinc coating is solid and enduring.
Complete protection: Every inch of a galvanized steel coil is protected, including recesses, sharp edges, and inaccessible areas, making it resistant to damage.
Ease of inspection: The product has simple structure and design, so it can be assessed readily by the naked eye and simple non-destructive thickness testing methods can be used.
