G90 Galvanized Coil refers to steel coil that has been coated with zinc using the galvanization process, with a coating designation of G90. The “G90” designation indicates the amount of zinc coating applied to the steel, specifically 0.90 ounces of zinc per square foot (or 0.27 ounces per side) of the steel sheet. This measurement reflects the total coating weight on both sides of the steel.
Key Features of G90 Galvanized Coil
- Corrosion Resistance: The primary benefit of G90 galvanization is excellent corrosion protection. The zinc coating acts as a barrier, preventing corrosive substances from reaching the underlying steel.
- Durability: G90 provides a robust layer of zinc, enhancing the steel’s lifespan, even in harsh environments.
- Sacrificial Protection: Even if the coating is scratched, the zinc will corrode first, protecting the steel underneath (galvanic protection).
- Weldability & Paintability: G90 galvanized steel can be welded using appropriate techniques. It can also be painted, but proper surface preparation is crucial for good adhesion.
Applications
G90 galvanized coil is widely used in various industries due to its balance of cost-effectiveness and corrosion resistance. Common applications include:
- Construction: Roofing, siding, framing, and structural components.
- Automotive: Body panels, undercarriage parts.
- HVAC: Ductwork, housings.
- Appliances: Appliance casings, components.
- General Manufacturing: Various fabricated parts and components requiring corrosion resistance.
Considerations When Choosing G90 Galvanized Coil
- Environment: Consider the specific environmental conditions the steel will be exposed to. While G90 offers good protection, extremely corrosive environments may require heavier coatings.
- Cost: G90 provides a balance between cost and performance. Explore alternatives like G60 or heavier coatings like G115 based on your budget and requirements.
- Formability: Galvanized steel can be formed and fabricated, but the zinc coating can affect the process. Consider the complexity of the forming operation when selecting the coating.
